CBT Test Assembly and Delivery 4 — Questions and Answers
Question 1: When a CBT program uses a 'continuous testing window,' which item management practice becomes especially critical?
- Administering all items only once
- Actively monitoring and rotating items to control exposure rates across the window (Correct answer)
- Locking the item bank at the start of the window
- Using a single fixed form for all examinees
Correct answer: Actively monitoring and rotating items to control exposure rates across the window
In continuous windows, items are repeatedly exposed, so systematic rotation and exposure control prevent item compromise over time.
Question 2: What is the function of an 'anchor item set' in equating CBT forms?
- Items that serve as a tutorial before the scored section
- A common set of items appearing on multiple forms used to statistically link scores to the same scale (Correct answer)
- Items flagged for immediate review after delivery
- The first and last items on every form
Correct answer: A common set of items appearing on multiple forms used to statistically link scores to the same scale
Anchor items appear on multiple forms and provide the statistical bridge needed to place scores from different forms onto a common reporting scale.
Question 3: A CBT system assigns each examinee a unique encrypted token at login. This token most directly supports:
- Adaptive item selection
- Binding the examinee's session to their identity and preventing session hijacking (Correct answer)
- Calculating raw scores in real time
- Controlling item randomization order
Correct answer: Binding the examinee's session to their identity and preventing session hijacking
Session tokens tie authentication credentials to the active testing session, ensuring no other party can inject into or take over the session.
Question 4: Which delivery model allows an examinee to take a CBT at home under live remote proctoring?
- Center-based fixed administration
- Online proctored (OP) or remote proctored delivery (Correct answer)
- Unproctored internet testing (UIT)
- Kiosk-mode delivery
Correct answer: Online proctored (OP) or remote proctored delivery
Online proctored delivery uses webcam monitoring, AI surveillance, and a live proctor to replicate center security conditions in a remote setting.
Question 5: In test center operations, 'throughput' refers to:
- The speed at which items are scored
- The number of examinees who can be tested per unit of time at a given facility (Correct answer)
- The rate at which items are loaded from the server
- The percentage of examinees who pass
Correct answer: The number of examinees who can be tested per unit of time at a given facility
Throughput measures testing center capacity — how many seats can be filled and completed per hour or day — affecting scheduling and appointment availability.
Question 6: What happens to an examinee's responses if they click 'Submit' before answering all items in a linear CBT?
- The system automatically answers remaining items correctly
- Unanswered items are typically scored as incorrect or omitted per the program's scoring policy (Correct answer)
- The exam restarts from the first unanswered item
- The proctor is prompted to extend testing time
Correct answer: Unanswered items are typically scored as incorrect or omitted per the program's scoring policy
Most CBT programs treat unanswered items at submission as omitted or wrong, as defined by the test's scoring rules.
Question 7: Which standard governs the physical accessibility requirements (e.g., wheelchair access, assistive technology) for CBT testing centers in the US?
- ISO 9001
- Americans with Disabilities Act (ADA) (Correct answer)
- FERPA
- NCLB
Correct answer: Americans with Disabilities Act (ADA)
The ADA mandates that testing facilities and delivery platforms provide reasonable accommodations and physical accessibility for examinees with disabilities.
