Transportation Security Officer (TSO) Certification Exam — Questions and Answers
Question 1: How should a TSO handle a passenger traveling with a CPAP machine?
- Allow it without any screening
- Require the passenger to check it as baggage
- Permit it as a carry-on and screen it separately from other bag contents (Correct answer)
- Prohibit it entirely due to its electronic components
Correct answer: Permit it as a carry-on and screen it separately from other bag contents
CPAP machines are allowed as carry-ons and are typically screened separately by placing them in a bin for X-ray imaging.
Question 2: A passenger's carry-on contains flare guns with flares. How should these be handled?
- Prohibited in both carry-on and checked baggage
- Permitted in carry-on if the flares are stored separately
- Permitted in checked baggage if properly declared and unloaded (Correct answer)
- Permitted in carry-on only if the passenger is a maritime safety officer
Correct answer: Permitted in checked baggage if properly declared and unloaded
Flare guns are treated as firearms and may be transported in checked baggage if unloaded, declared to the airline, and stored in a hard-sided locked container.
Question 3: How should a TSO handle a situation where a passenger's medical device triggers the metal detector?
- Ask the passenger to remove the device for X-ray screening
- Wave the passenger through without further screening
- Deny the passenger entry to the sterile area
- Follow alternate screening procedures and treat the passenger with dignity (Correct answer)
Correct answer: Follow alternate screening procedures and treat the passenger with dignity
Medical devices cannot be removed, so TSOs must apply alternate screening methods while maintaining passenger dignity.
Question 4: What does the acronym ETD stand for in airport security screening?
- Electronic Threat Detection
- Enhanced Transportation Detection
- Explosive Trace Detection (Correct answer)
- Electronic Trace Diagnostics
Correct answer: Explosive Trace Detection
ETD stands for Explosive Trace Detection, a screening method that identifies microscopic explosive residue collected on swabs from surfaces.
Question 5: A TSO notices a cylindrical object with wires attached in a passenger's carry-on. The passenger says it is a portable battery pack. What is the best course of action?
- Remove the item and discard it
- Clear the bag since battery packs are common
- Perform additional X-ray views and request physical inspection to verify the item (Correct answer)
- Allow the bag through and note the incident
Correct answer: Perform additional X-ray views and request physical inspection to verify the item
Wires attached to cylindrical objects are a potential IED indicator requiring additional imaging views and physical inspection before clearing.
Question 6: What is the purpose of the 'resolution pat-down' compared to a standard pat-down?
- It is targeted to a specific area identified by imaging or alarm (Correct answer)
- It is more invasive and covers the entire body
- It replaces AIT scanning for all passengers
- It is only used for PreCheck passengers
Correct answer: It is targeted to a specific area identified by imaging or alarm
A resolution pat-down is targeted to the specific area flagged by AIT or alarm technology to resolve the detected anomaly.
Question 7: A passenger presents a personal water bottle that is full of water. How should the TSO handle this?
- Require the passenger to empty it before proceeding through the checkpoint (Correct answer)
- Allow it since water is not a threat
- Confiscate it regardless of what the liquid is
- Allow it if the passenger drinks from it to prove it is water
Correct answer: Require the passenger to empty it before proceeding through the checkpoint
Passengers must empty reusable water bottles before the checkpoint; empty bottles can pass through and be refilled after security.
Question 8: What is the correct order of steps when a passenger's Advanced Imaging Technology (AIT) scan shows an alarm?
- Inform the passenger of the alarm location, conduct a targeted pat-down, and resolve the alarm (Correct answer)
- Immediately call law enforcement before touching the passenger
- Visually inspect the clothing and clear the passenger
- Send the passenger back through AIT, then pat-down, then resolve
Correct answer: Inform the passenger of the alarm location, conduct a targeted pat-down, and resolve the alarm
When AIT flags an alarm, the officer informs the passenger of the location and conducts a targeted pat-down to resolve it.
Question 9: What is the primary purpose of the Transportation Security Clearinghouse (TSC) in the TSO accreditation process?
- Administering the written certification exam
- Conducting background check data management and coordination (Correct answer)
- Issuing TSO identification badges
- Approving TSO uniforms and equipment
Correct answer: Conducting background check data management and coordination
The TSC coordinates the collection and verification of background investigation data for TSO candidates.
Question 10: Which situation would most likely require a TSO to complete a Significant Incident Report (SIR)?
- A passenger who forgot their boarding pass
- A discovery of a firearm in carry-on baggage (Correct answer)
- A passenger requesting a private screening
- A long queue at the checkpoint during peak hours
Correct answer: A discovery of a firearm in carry-on baggage
Discovery of a firearm in carry-on baggage is a significant security incident requiring formal documentation via a SIR.
Question 11: Which of the following best describes TSA's use of the 'tell, show, ask' model during pat-downs?
- Tell the passenger what you found, show them the item, ask if it is theirs
- Tell a supervisor, show them the passenger, ask for instructions
- Tell law enforcement, show ID, ask for authority to proceed
- Tell the passenger what you will do, show the technique on yourself if needed, ask for their cooperation (Correct answer)
Correct answer: Tell the passenger what you will do, show the technique on yourself if needed, ask for their cooperation
The 'tell, show, ask' model involves informing the passenger of the procedure, demonstrating the technique if helpful, and requesting their cooperation.
Question 12: What is the primary purpose of the Behavior Detection Officer (BDO) program at TSA checkpoints?
- To identify passengers exhibiting behaviors that may indicate a threat (Correct answer)
- To conduct random bag checks
- To manage passenger flow and reduce wait times
- To verify boarding passes against flight manifests
Correct answer: To identify passengers exhibiting behaviors that may indicate a threat
BDOs are trained to identify stress, fear, and deceptive behaviors that may indicate a security threat through observation techniques.
Question 13: A supervisor asks a TSO to pass a bag through screening without full inspection due to long lines. The TSO should:
- Comply to maintain checkpoint throughput
- Screen only the outside of the bag quickly
- Refuse and follow standard screening procedures (Correct answer)
- Request a written order before complying
Correct answer: Refuse and follow standard screening procedures
TSOs must follow all standard screening procedures regardless of queue length or supervisor pressure that violates protocol.
Question 14: What should a TSO do if they notice a bag left unattended near the checkpoint with no visible owner?
- Move it to lost and found immediately
- Open it to search for identification
- Ignore it if it appears small and harmless
- Treat it as a potential threat, keep people away, and notify law enforcement per protocol (Correct answer)
Correct answer: Treat it as a potential threat, keep people away, and notify law enforcement per protocol
Unattended baggage is treated as a potential security threat; TSOs must follow protocol by securing the area and notifying law enforcement.
Question 15: A passenger presents a state-issued ID that appears to be expired by two weeks. What should the TSO do?
- Refer the passenger to document verification procedures per current TSA policy (Correct answer)
- Automatically deny boarding
- Confiscate the ID as fraudulent
- Accept the ID without question
Correct answer: Refer the passenger to document verification procedures per current TSA policy
TSA policy provides guidance on accepting recently expired IDs and may allow passengers to proceed through identity verification procedures.
Question 16: Which of the following best describes a 'dual-use' item in aviation security?
- An item that can be used in both domestic and international flights
- An item that is harmless in normal use but can potentially be used as a weapon (Correct answer)
- An item that must be screened twice
- An item approved for both carry-on and checked baggage
Correct answer: An item that is harmless in normal use but can potentially be used as a weapon
Dual-use items are everyday objects—such as walking canes, umbrellas, or sporting equipment—that serve legitimate purposes but could be weaponized.
Question 17: A passenger is traveling with medically necessary liquids in a container larger than 3.4 ounces. Which of the following is the correct procedure for the TSO to follow?
- Confiscate the item as it exceeds the 3-1-1 rule limit.
- Inform the passenger that the item requires additional screening and separate it from other belongings. (Correct answer)
- Instruct the passenger to discard a portion of the liquid until it is less than 3.4 ounces.
- Allow the item but require the passenger to check it in their baggage.
Correct answer: Inform the passenger that the item requires additional screening and separate it from other belongings.
TSA procedures allow for medically necessary liquids in amounts greater than 3.4 ounces, but they must be declared to an officer and undergo additional screening, which may include X-ray, bottled liquid scanning, or other methods.
Question 18: During a pat-down, a passenger informs the TSO that they have a sensitive medical device on their abdomen. How should the TSO proceed?
- Stop the pat-down immediately and clear the passenger.
- Insist on patting down the area to ensure no prohibited items are concealed.
- Conduct a visual inspection of the area and pat-down the surrounding areas. (Correct answer)
- Inform the passenger the device must be removed for screening.
Correct answer: Conduct a visual inspection of the area and pat-down the surrounding areas.
TSOs are trained to be respectful of passengers' medical conditions. When informed about a medical device or a painful area, the officer should adjust the procedure, which typically involves a visual inspection and a careful pat-down around the affected area, rather than directly on it.
Question 19: Under what condition may a TSO conduct a pat-down on a minor?
- Whenever a supervisor requests it
- Only when the minor alarms the screening equipment and alternative resolution is not possible, with a parent or guardian present (Correct answer)
- Never under any circumstance
- Only for international flights
Correct answer: Only when the minor alarms the screening equipment and alternative resolution is not possible, with a parent or guardian present
Pat-downs of minors follow strict TSA protocols, are only conducted when necessary, and should be performed with a parent or guardian present.
Question 20: Which action is an example of maintaining situational awareness at a checkpoint?
- Monitoring the entire checkpoint environment including passenger behavior and surroundings (Correct answer)
- Tracking only flagged passengers after they have been identified
- Focusing exclusively on the X-ray monitor to avoid distractions
- Chatting with coworkers to stay alert during slow periods
Correct answer: Monitoring the entire checkpoint environment including passenger behavior and surroundings
Situational awareness requires continuously monitoring the broader environment, not just one station or already-identified individuals.
Question 21: On a dual-energy X-ray system, items with HIGH atomic numbers (Z-number) typically appear in which color?
- Blue or green (Correct answer)
- Orange or amber
- Red
- Transparent
Correct answer: Blue or green
High-Z materials such as metals are assigned blue or green colors on dual-energy X-ray systems to help officers quickly identify them.
Question 22: What does a 'cluttered' X-ray image typically indicate about the bag being screened?
- The bag contains mostly liquids
- Many overlapping items make it harder to identify individual objects and may require unpacking (Correct answer)
- The X-ray machine is malfunctioning
- The bag contains only organic materials
Correct answer: Many overlapping items make it harder to identify individual objects and may require unpacking
A cluttered image with many overlapping items reduces a TSO's ability to clearly identify objects and may require the passenger to reorganize or unpack the bag.
Question 23: When communicating with a passenger who has identified themselves as deaf or hard of hearing, which action is most critical for the TSO to perform?
- Speak very loudly and directly into the passenger's ear.
- Quickly perform a pat-down to avoid the difficulty of communication.
- Face the passenger directly, maintain eye contact, and use visual cues or written notes. (Correct answer)
- Rely exclusively on their traveling companion for all communication.
Correct answer: Face the passenger directly, maintain eye contact, and use visual cues or written notes.
To facilitate communication with a person who is deaf or hard of hearing, it is essential to face them so they can see your lips and facial expressions. Maintaining eye contact shows you are engaged. Supplementing verbal communication with clear gestures, pointing, or writing things down ensures the message is understood. TSA provides resources like notification cards for passengers to discreetly inform officers of a disability.
Question 24: Which behavior by a TSO BEST demonstrates professional conduct toward all passengers?
- Skipping pleasantries to process passengers faster
- Applying stricter scrutiny to passengers who match a specific profile
- Focusing only on passengers who appear nervous or suspicious
- Greeting every passenger consistently and applying procedures uniformly (Correct answer)
Correct answer: Greeting every passenger consistently and applying procedures uniformly
Consistent, uniform treatment of all passengers upholds civil rights and TSA non-discrimination standards.
Question 25: What is the role of a 'Coach' in the TSA's on-the-job training program?
- To administer written examinations
- To conduct covert testing of new officers
- To provide real-time guidance and feedback to trainees during live operations (Correct answer)
- To approve officer schedules
Correct answer: To provide real-time guidance and feedback to trainees during live operations
TSA Coaches are experienced, trained mentors who guide new officers through live checkpoint operations and provide immediate performance feedback.
Question 26: TSA's English language proficiency requirement for TSO candidates exists primarily because:
- TSOs must communicate clearly with passengers, colleagues, and law enforcement in English (Correct answer)
- TSA SOPs are only available in English and cannot be translated
- Most security threats involve non-English-speaking passengers
- Federal law prohibits bilingual screening personnel
Correct answer: TSOs must communicate clearly with passengers, colleagues, and law enforcement in English
Clear English communication is operationally essential for TSOs to direct passengers, coordinate with teams, and relay security information.
Question 27: A passenger approaches you speaking loudly and using aggressive body language. What is the BEST first response?
- Match their volume and assert authority immediately
- Walk away until they calm down on their own
- Call for backup before engaging with the passenger
- Remain calm, speak in a low steady tone, and acknowledge their concern (Correct answer)
Correct answer: Remain calm, speak in a low steady tone, and acknowledge their concern
De-escalation starts with a calm voice and acknowledgment, which tends to reduce a passenger's agitation rather than inflame it.
Question 28: Under TSA policy, which category of item requires an airline's approval before it can be transported in checked baggage?
- Dry ice up to 5.5 pounds used to pack perishables
- Firearms with fewer than 11 rounds of ammunition
- All items in the above categories
- Lithium-ion batteries between 100 Wh and 160 Wh (Correct answer)
Correct answer: Lithium-ion batteries between 100 Wh and 160 Wh
Lithium-ion batteries between 100 Wh and 160 Wh require specific airline approval before transport, while firearms and small quantities of dry ice follow separate TSA/FAA rules.
Question 29: Which of these knife types is ALWAYS prohibited in carry-on baggage regardless of blade length?
- Folding knife with a locking blade under 2.36 inches
- Box cutter / razor blade (Correct answer)
- Swiss Army knife
- Pocket knife with a 2-inch blade
Correct answer: Box cutter / razor blade
Box cutters and loose razor blades are prohibited in carry-on regardless of size; folding knives under 2.36 inches with non-locking blades were previously allowed but all sharp items are now generally restricted.
Question 30: A passenger's bag shows a large orange-amber blob obscuring a section of the image. What technique can the officer use to better evaluate what is underneath?
- Rotate the bag 180 degrees and re-scan
- Flag the bag for a physical search without further X-ray review
- Manually move the organic item and re-scan the bag
- Use the organic-stripping or color-inversion feature to suppress the organic layer and reveal underlying items (Correct answer)
Correct answer: Use the organic-stripping or color-inversion feature to suppress the organic layer and reveal underlying items
Organic stripping electronically removes the orange organic overlay to expose potentially hidden metallic or inorganic threat items.
Question 31: Which of the following is NOT a category of prohibited items that TSOs screen for?
- Explosives
- Incendiaries
- Prescription medications in original containers (Correct answer)
- Prohibited firearms
Correct answer: Prescription medications in original containers
Prescription medications in original labeled containers are generally permitted through security checkpoints.
Question 32: TSA's 'Continuous Online Readiness Training' (CORT) requirement means that certified TSOs must:
- Attend a week-long refresher course every six months
- Complete new hire training every year regardless of experience
- Regularly complete online modules to maintain and update their skills (Correct answer)
- Pass a physical fitness test quarterly
Correct answer: Regularly complete online modules to maintain and update their skills
CORT is an ongoing online training requirement that keeps TSOs current on evolving threats, procedures, and policies.
Question 33: How often are TSOs required to test screening equipment such as X-ray machines and ETD devices?
- Annually during TSA audits only
- At intervals specified by TSA standard operating procedures, typically at the start of each shift (Correct answer)
- Only when a malfunction is reported
- Once a week regardless of use
Correct answer: At intervals specified by TSA standard operating procedures, typically at the start of each shift
TSA SOPs require equipment testing at regular intervals, typically at the start of each shift, to ensure operational accuracy and reliability.
Question 34: A passenger arrives at the checkpoint with a snow globe larger than 3.4 ounces. What should the TSO advise?
- Test it with ETD swabs and allow it if negative
- Inform the passenger it must be checked or surrendered, as it exceeds the liquid limit (Correct answer)
- Allow it through in a quart-sized bag
- Freeze it to pass as a solid
Correct answer: Inform the passenger it must be checked or surrendered, as it exceeds the liquid limit
Snow globes containing liquid exceeding 3.4 ounces are not permitted in carry-on baggage and must be checked or surrendered.
Question 35: A TSO observes an X-ray image with an object that appears as a solid orange rectangle with no distinguishable internal structure. What is the most appropriate response?
- Clear the bag since organic materials are usually harmless
- Mark it as food and allow it through without further action
- Escalate directly to law enforcement without further screening steps
- Flag the bag for additional screening because solid undifferentiated masses can conceal threats (Correct answer)
Correct answer: Flag the bag for additional screening because solid undifferentiated masses can conceal threats
Solid undifferentiated masses with no visible internal structure are a concealment red flag and warrant additional screening to identify the contents.
Question 36: A bag shows a large, dense white rectangular block that fills much of the image and has no visible internal detail. This is most consistent with:
- An ice pack or gel cooler
- A lead-lined bag intended to block X-rays, which itself is cause for additional screening (Correct answer)
- A heavy textbook
- A laptop computer with a depleted battery
Correct answer: A lead-lined bag intended to block X-rays, which itself is cause for additional screening
Lead-lined bags are designed to block X-rays and produce a featureless bright white rectangle; TSA policy requires additional screening when contents cannot be evaluated.
Question 37: What is the required TSO action when explosive trace detection (ETD) from a pat-down glove swab returns an alarm?
- Immediately arrest the passenger
- Conduct additional screening and notify a supervisor per alarm resolution protocols (Correct answer)
- Re-swab the same area and average the results
- Dismiss the result if the passenger appears non-threatening
Correct answer: Conduct additional screening and notify a supervisor per alarm resolution protocols
An ETD alarm requires additional screening steps and supervisor notification in accordance with alarm resolution protocols.
Question 38: What must a TSO do before touching a passenger's head or hair during a pat-down?
- Don gloves specifically rated for hair contact
- Obtain written consent from the passenger
- Ask the passenger if they have any head injuries or sensitivities and explain the procedure (Correct answer)
- Have a supervisor physically present
Correct answer: Ask the passenger if they have any head injuries or sensitivities and explain the procedure
Officers must ask about sensitivities and explain what they will do before touching the head or hair area.
Question 39: A passenger alarms the Advanced Imaging Technology (AIT) scanner. According to TSA procedures, which of the following is the most appropriate next step for the TSO?
- Direct the passenger to a private screening area for a bag search.
- Ask the passenger to go through the AIT scanner a second time.
- Conduct a pat-down procedure to resolve the alarm. (Correct answer)
- Immediately conduct a pat-down of the passenger's entire body.
Correct answer: Conduct a pat-down procedure to resolve the alarm.
When a passenger alarms the AIT or a walk-through metal detector, the standard procedure is to perform a pat-down to identify and resolve the source of the alarm. While other steps might be taken in different situations, the direct response to an AIT alarm is a pat-down.
Question 40: Which of the following citizenship or residency statuses would disqualify a candidate from TSO accreditation?
- Lawful permanent resident (green card holder)
- Naturalized U.S. citizen
- Non-immigrant visa holder with work authorization (Correct answer)
- U.S. citizen born abroad to American parents
Correct answer: Non-immigrant visa holder with work authorization
TSO positions require U.S. citizenship or lawful permanent resident status; non-immigrant visa holders are ineligible.
Question 41: What does AIT stand for in TSA checkpoint operations?
- Advanced Imaging Technology (Correct answer)
- Airport Identification Terminal
- Automated Imaging Technology
- Authorized Inspection Tool
Correct answer: Advanced Imaging Technology
AIT stands for Advanced Imaging Technology, which includes millimeter wave scanners used at TSA checkpoints.
Question 42: Within TSA's layered security approach, ETD screening is best classified as:
- The mandatory primary screening method applied to all passengers
- A behavioral detection and observation tool
- A supplemental or resolution screening method used in specific situations (Correct answer)
- An administrative document verification technique
Correct answer: A supplemental or resolution screening method used in specific situations
ETD functions as a supplemental or resolution screening method, used to enhance security or resolve alarms rather than as the standard first-pass screening for all passengers.
Question 43: When swabbing a carry-on bag for ETD analysis, which areas should a TSO focus on?
- The manufacturer's identification label inside the bag
- Interior and exterior surfaces, especially handles and frequently touched areas (Correct answer)
- Only the exterior zippers and seams
- Only the interior bottom lining of the bag
Correct answer: Interior and exterior surfaces, especially handles and frequently touched areas
ETD swabbing of bags should cover both interior and exterior surfaces, focusing on handles and frequently touched areas where residue is most likely to accumulate.
Question 44: Which of the following is required for all candidates applying for the TSO role?
- Previous law enforcement experience
- College degree
- Military background
- Ability to work irregular hours, including weekends and holidays (Correct answer)
Correct answer: Ability to work irregular hours, including weekends and holidays
The role of a Transportation Security Officer demands flexibility due to the 24/7 nature of airport operations and security needs. Candidates must be willing and able to work irregular hours, including early mornings, late nights, weekends, and holidays. This requirement is essential to ensure adequate staffing and continuous security coverage at all times.
Question 45: During screening with the Advanced Imaging Technology (AIT), an anomaly is detected on a passenger. The passenger refuses a pat-down. What is the most likely outcome?
- The TSO will conduct a pat-down against the passenger's will.
- The passenger will be denied access to the sterile area and will not be able to board their flight. (Correct answer)
- The passenger will be allowed to proceed to their flight after a verbal warning.
- The passenger will be offered an alternative screening method, such as a walk-through metal detector.
Correct answer: The passenger will be denied access to the sterile area and will not be able to board their flight.
While passengers can opt out of AIT screening in favor of a pat-down, refusing a required pat-down to resolve an alarm or anomaly will result in being denied access to the secure area of the airport and thus, the flight.
Question 46: Which of the following best describes a 'dry run' in the context of aviation security threats?
- A test run by terrorists to probe security vulnerabilities without committing an actual attack (Correct answer)
- A practice fire drill conducted by airport staff
- A TSA training exercise at a checkpoint
- An aircraft maintenance simulation
Correct answer: A test run by terrorists to probe security vulnerabilities without committing an actual attack
A dry run is when a would-be attacker rehearses an attack plan, testing security responses and identifying weaknesses without executing the attack.
Question 47: The concept of 'layered security' in an airport environment means that:
- Multiple, overlapping security measures are in place, so that if one layer is bypassed, another is likely to detect the threat. (Correct answer)
- The TSO's role at the checkpoint is the single most important and final layer of defense against threats.
- Passengers are screened multiple times using the exact same procedure to ensure nothing is missed.
- Each security function, like the TDC and X-ray, operates independently to prevent a single point of failure.
Correct answer: Multiple, overlapping security measures are in place, so that if one layer is bypassed, another is likely to detect the threat.
Layered security is a core principle where security is not dependent on a single measure. It combines various elements—such as intelligence, passenger vetting, law enforcement presence, access controls, and checkpoint screening—to create a multi-faceted defense. A failure at one point can be caught by another, increasing overall security effectiveness.
Question 48: Which of the following describes a 'liquid explosive' threat that prompted the TSA 3-1-1 liquids rule?
- Standard aerosol hairspray
- Energy drinks with high caffeine content
- Explosive compounds that can be mixed from liquids carried separately onto aircraft (Correct answer)
- Bottled water purchased outside the security zone
Correct answer: Explosive compounds that can be mixed from liquids carried separately onto aircraft
The 3-1-1 rule was implemented after the 2006 liquid bomb plot, where terrorists planned to mix liquid components to create explosives aboard aircraft.
Question 49: How long must a TSO applicant have been a U.S. citizen or national prior to applying?
- At least 5 years prior to application
- At least 3 years prior to application
- At least 1 year prior to application
- No waiting period — citizenship at time of application is sufficient (Correct answer)
Correct answer: No waiting period — citizenship at time of application is sufficient
TSA requires applicants to be a U.S. citizen or national at the time of application; there is no minimum duration of citizenship required.
Question 50: During a pat-down, a TSO must check which area using the front of the hand?
- Breast area
- Inner thigh
- Outer arms and legs (Correct answer)
- Groin area
Correct answer: Outer arms and legs
The front of the hand is used for non-sensitive areas such as outer arms and legs, while the back of the hand is used for sensitive areas.
Question 51: Which of the following disqualifies an applicant from TSO employment under felony conviction rules?
- A felony conviction within the past 5 years only
- Any felony conviction regardless of when it occurred (Correct answer)
- A misdemeanor conviction more than 10 years ago
- A felony conviction that resulted in a fine rather than prison
Correct answer: Any felony conviction regardless of when it occurred
TSA policy disqualifies any applicant with a felony conviction regardless of how long ago it occurred or the sentence imposed.
Question 52: What does the term 'artfully concealed' mean in the context of TSO threat recognition?
- Prohibited items hidden within everyday objects to avoid detection (Correct answer)
- Liquids packed in clear ziplock bags
- Sharp objects wrapped in clothing
- Items stored in TSA-approved containers
Correct answer: Prohibited items hidden within everyday objects to avoid detection
Artfully concealed refers to prohibited items deliberately hidden inside ordinary objects such as books, electronics, or food containers to evade X-ray detection.
Question 53: If a passenger refuses to complete a pat-down after initially agreeing, the TSO should:
- Allow the passenger to proceed without further screening
- Forcibly complete the screening for security reasons
- Inform the passenger they will not be permitted to fly and notify a supervisor (Correct answer)
- Offer the passenger an alternative form of ID verification
Correct answer: Inform the passenger they will not be permitted to fly and notify a supervisor
A passenger who refuses to complete a required pat-down cannot be permitted to enter the sterile area and the officer must notify a supervisor.
Question 54: What is the primary purpose of TSA's Behavioral Detection Officer (BDO) program?
- To assist passengers with lost luggage claims
- To randomly select passengers for enhanced screening via SSSS
- To identify individuals exhibiting suspicious behaviors that may indicate a security threat (Correct answer)
- To enforce immigration laws at airport checkpoints
Correct answer: To identify individuals exhibiting suspicious behaviors that may indicate a security threat
BDOs are trained to observe and identify clusters of behaviors and appearance indicators that may signal deceptive intent or a security threat.
Question 55: A TSO at the Travel Document Checker (TDC) podium observes that the name on a passenger's government-issued ID is a common variation of the name on their boarding pass (e.g., 'Mike' on the ID and 'Michael' on the boarding pass). According to standard procedure, what is the TSO's correct initial action?
- Advise the passenger to return to the airline check-in counter to have their boarding pass reissued to match the ID. (Correct answer)
- Allow the passenger to proceed as the name variation is common.
- Refer the passenger to a Supervisory TSO for identity verification.
- Deny the passenger entry and instruct them to call airport police.
Correct answer: Advise the passenger to return to the airline check-in counter to have their boarding pass reissued to match the ID.
The SOP requires that the name on the travel document and the government-issued ID must match. The airline is responsible for issuing the boarding pass correctly. Therefore, the TSO's role is to identify the discrepancy and direct the passenger to the airline to resolve the issue, ensuring the passenger's identity is consistent across all documents.
Question 56: What is a 'private screening' and when should it be offered?
- A screening conducted out of public view at a passenger's request or when sensitive areas must be screened (Correct answer)
- A screening reserved for TSA PreCheck members only
- A screening done in a back office for all first-class passengers
- A remote video screening option
Correct answer: A screening conducted out of public view at a passenger's request or when sensitive areas must be screened
Private screening is offered when a passenger requests it or when a pat-down involves sensitive areas of the body, ensuring dignity and privacy.
Question 57: What is the purpose of the Known Crewmember (KCM) program at airport security checkpoints?
- To allow airline crew members to bypass all forms of security screening
- To allow vetted airline crew members to use a streamlined identity verification process (Correct answer)
- To give crew members priority lane access without identity checks
- To exempt crew from the 3-1-1 liquids rule only
Correct answer: To allow vetted airline crew members to use a streamlined identity verification process
KCM allows verified airline crew members to use dedicated lanes with identity verification, though they remain subject to random screening.
Question 58: A passenger claims ownership of a bag only after being told it will be abandoned and destroyed. This behavior is:
- Grounds to waive screening
- A potential indicator of someone who placed an item and is now reassessing (Correct answer)
- Normal behavior for nervous flyers
- A sign of forgetfulness typical of frequent travelers
Correct answer: A potential indicator of someone who placed an item and is now reassessing
Delayed claim of ownership, especially after threat of destruction, is a recognized behavioral indicator that warrants additional screening.
Question 59: What does the term 'CBRN' stand for in the context of security threats?
- Cargo Bay Reconnaissance Network
- Civilian Background Research Notes
- Checkpoint Baggage Review Notification
- Chemical, Biological, Radiological, and Nuclear (Correct answer)
Correct answer: Chemical, Biological, Radiological, and Nuclear
CBRN refers to Chemical, Biological, Radiological, and Nuclear threats — categories of weapons capable of mass casualties.
Question 60: What is the correct procedure when ETD (Explosive Trace Detection) equipment produces an alarm?
- Retest with the same swab to confirm
- Immediately evacuate the checkpoint
- Conduct additional screening and notify a supervisor (Correct answer)
- Allow the passenger through and note the incident in a log
Correct answer: Conduct additional screening and notify a supervisor
An ETD alarm requires additional screening steps and supervisor notification to determine if a threat exists.
Question 61: A TSO is patting down a passenger and feels an item that could be a prohibited item but could also be a medical device. What is the appropriate next step?
- Assume it is medical and clear the passenger
- Pat the area again and if unsure, clear the passenger
- Immediately call law enforcement without speaking to the passenger
- Ask the passenger what the item is and, if not resolved, conduct additional screening per protocols (Correct answer)
Correct answer: Ask the passenger what the item is and, if not resolved, conduct additional screening per protocols
Officers should ask the passenger about the item and, if the explanation does not resolve the concern, escalate to additional screening per standard protocols.
Question 62: During a pat-down, the TSO notices the passenger is visibly distressed and crying. What is the best action?
- Call for a behavioral detection officer before proceeding
- Proceed without acknowledgment to finish quickly
- Immediately stop and let the passenger go to avoid further distress
- Pause, acknowledge the passenger's feelings, offer private screening if not already offered, and continue professionally (Correct answer)
Correct answer: Pause, acknowledge the passenger's feelings, offer private screening if not already offered, and continue professionally

Question 85: While analyzing an X-ray image of a carry-on bag, a TSO observes an object that displays as a dense, dark blue color. The item is uniformly shaped and lacks any moving parts or wires. Based on standard color interpretation, which of the following is the most likely category for this item?
- A dense metal object, such as a firearm component (Correct answer)
- A block of cheese
- A collection of paper documents
- A plastic water bottle filled with liquid
Correct answer: A dense metal object, such as a firearm component
On a standard X-ray scanner display, different colors represent different material densities. Blue typically indicates dense, inorganic materials like metals. Organic materials, such as food (cheese) and paper, appear as orange. Less dense materials like plastics may appear green or orange. Therefore, a dense, dark blue object is most indicative of metal, which could be a firearm or another prohibited item.
Question 86: During X-ray screening, a TSO encounters a laptop computer inside a carry-on bag. The image of the laptop displays a mixture of green, blue, and some orange components. Why does the laptop appear with multiple colors?
- The laptop is made of a single, unknown material that reflects all colors.
- The X-ray machine is malfunctioning and showing incorrect colors.
- It contains a complex mix of materials, including plastics, metals, and a circuit board. (Correct answer)
- Laptops are exempt from standard color-coding rules.
Correct answer: It contains a complex mix of materials, including plastics, metals, and a circuit board.
Electronic devices like laptops are made from a variety of materials. The green color indicates a mix of organic and inorganic components (like the circuit board), blue indicates dense metals (in ports and internal structures), and orange can represent lighter plastics or other organic parts. This mixture of colors is characteristic of complex electronic items.
Question 87: A TSO notices a laptop-sized object that displays as a solid, uniformly dark rectangle with no internal components visible. This should raise suspicion because:

Question 99: A passenger places a laptop in their carry-on bag instead of a bin. What should the TSO instruct?
- Use ETD swabs on the bag instead
- Skip screening that bag to avoid delay
- Ask the passenger to remove the laptop and place it in a separate bin for X-ray screening (Correct answer)
- Allow it since it will still pass through the X-ray
Correct answer: Ask the passenger to remove the laptop and place it in a separate bin for X-ray screening
Laptops must be removed from bags and placed separately in a bin so X-ray operators can get a clear image of both the device and the bag.
Question 100: During a pat-down, a passenger becomes uncomfortable and asks the TSO to stop. The CORRECT response is:
- Immediately abandon the screening and allow them to proceed
- Continue the pat-down since it is required by law regardless of passenger objection
- Pause and explain that the screening must be completed but they may request a private area or same-gender screener (Correct answer)
- Summon law enforcement to compel the passenger to comply
Correct answer: Pause and explain that the screening must be completed but they may request a private area or same-gender screener
TSA policy requires completing necessary screening while offering accommodations such as privacy and same-gender screeners to address passenger discomfort.
