AFCT Armed Forces Classification Test Study Guide
The Armed Forces Classification Test (AFCT) is the in-service equivalent of the ASVAB. It is administered to active-duty servicemembers who want to improve their subtest scores in order to qualify for MOS (Military Occupational Specialty) reclassification, re-enlistment bonuses, or advanced training programs. The AFCT uses the exact same format and content as the corresponding ASVAB subtests.
Unlike the initial ASVAB taken at MEPS, the AFCT is administered at Military Entrance Testing (MET) sites or on-post education centers after a servicemember requests retesting through their unit. Score improvements on the AFCT replace the original ASVAB subtest scores for classification purposes.
AFCT Subtests and Content Areas
The AFCT covers the same subtest areas as the ASVAB. The four core subtests used in most MOS composite scores are:
- Arithmetic Reasoning (AR) — word problems requiring you to set up and solve math equations. Covers percentages, ratios, rates, and basic algebra applied to real-world scenarios.
- Word Knowledge (WK) — vocabulary questions asking for synonyms or the best meaning of a word in context. A strong vocabulary is built through consistent reading practice.
- Paragraph Comprehension (PC) — short reading passages followed by questions that test your ability to identify main ideas, infer meaning, and draw conclusions.
- Mathematics Knowledge (MK) — algebra, geometry, number properties, and mathematical concepts tested in a straightforward format without word-problem framing.
Additional Subtests for Specialized MOS
Depending on the target MOS, a servicemember may also need to improve scores in:
If you want more targeted practice, the afct practice test page covers the same material with additional questions and explanations.
- Mechanical Comprehension (MC) — principles of mechanics, physics, and how machines work (gears, pulleys, levers, hydraulics).
- Electronics Information (EI) — basic electricity, circuits, electronic components, and radio/communications concepts.
- Auto and Shop Information (AS) — automotive systems, shop tools, and basic repair procedures.
Identify which ASVAB composite score your target MOS requires and which subtests contribute to it Review Arithmetic Reasoning — focus on setting up equations from word problems, not just computation Study Word Knowledge by building vocabulary with synonym practice and flashcards Practice Paragraph Comprehension with timed reading passages to improve reading speed and retention Drill Mathematics Knowledge covering algebra (solving for x), geometry (area, perimeter, angles), and number properties If targeting a technical MOS, add Mechanical Comprehension — study pulleys, gears, levers, and fluid mechanics For electronics or signal MOS paths, review Electronics Information covering circuits, ohms, and components For automotive or maintenance MOS, study Auto and Shop Information on engine systems and hand tools Take full-length timed AFCT/ASVAB practice tests to simulate real test pacing and build endurance Coordinate with your unit education center to schedule the AFCT and confirm any waiting period requirements MEPS vs. MET Site Testing
Initial ASVAB testing for enlistment occurs at a Military Entrance Processing Station (MEPS), which is a fully controlled federal testing environment. The AFCT, however, is taken at a Military Entrance Testing (MET) site — typically located at National Guard armories, reserve centers, or on-post education facilities.
Both testing environments use the same computerized adaptive format for most subtests. Servicemembers are generally required to wait a minimum period (often 30 days) between retests, and the number of retakes may be limited. Always verify current retesting policies with your unit S1 or education office before scheduling.
Scoring on the AFCT is identical to the ASVAB — each subtest produces a scaled score that feeds into composite line scores used to determine MOS eligibility. A higher composite score opens access to more specialized and higher-paying MOS opportunities.

Sample Armed Forces Classification Test Practice Questions
Try these questions from our free Armed Forces Classification Test practice tests. The correct answer and an explanation follow each question.
What happens to the brightness of bulbs connected in series when one bulb burns out?
- A. Remaining bulbs get brighter
- B. All bulbs go out
- C. Remaining bulbs are unaffected
- D. Only adjacent bulbs go out
Answer: B. All bulbs go out
In a series circuit, all components share a single current path. If one bulb burns out, the circuit is broken and all bulbs go out.
In a schematic diagram, what does a circle with a sine wave (~) inside it represent?
- A. A DC voltage source
- B. A fuse
- C. A ground connection
- D. An AC voltage source
Answer: D. An AC voltage source
This is the standard symbol for an Alternating Current (AC) voltage source. The sine wave illustrates the nature of AC, where the voltage and current periodically reverse direction. This is distinct from a DC source, which is often shown with '+' and '-' symbols.
According to Kirchhoff's Current Law, what happens at a junction in an electrical circuit?
- A. Voltage is equal across all branches
- B. The sum of currents entering the junction equals the sum of currents leaving it
- C. Resistance increases at every junction
- D. Power is equally distributed among all branches
Answer: B. The sum of currents entering the junction equals the sum of currents leaving it
Kirchhoff's Current Law (KCL) states that the total current entering a junction must equal the total current leaving it. This is based on the conservation of electric charge.
Select the word that is most nearly opposite in meaning to "arrogant."
- A. Proud
- B. Humble
- C. Boastful
- D. Confident
Answer: B. Humble
"Arrogant" describes someone who has an exaggerated sense of their own importance or abilities, often displaying a superior and disdainful attitude. The opposite of this self-importance is "humble," which means having or showing a modest or low estimate of one's own importance. Humility contrasts directly with arrogance.

Is the AFCT the same as the ASVAB?
Yes, the AFCT uses the same content and format as the ASVAB subtests. The difference is that the AFCT is administered to active-duty servicemembers seeking to improve their scores for MOS reclassification or re-enlistment, rather than to civilians entering the military for the first time.
How do I qualify to take the AFCT?
You must be an active-duty servicemember. The process typically requires a request through your unit chain of command or education center. There may be a mandatory waiting period since your last ASVAB or AFCT attempt, often 30 days for the first retest and 6 months for subsequent retests, though policies vary by branch.
Which subtests should I focus on for MOS reclassification?
It depends on your target MOS. Most combat and administrative MOS paths rely on the Skilled Technical (ST) or General Technical (GT) composite, which includes Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, and Mathematics Knowledge. Technical and electronics MOS paths additionally require strong Mechanical Comprehension and Electronics Information scores.
Will my AFCT scores replace my original ASVAB scores?
Yes. If you score higher on an AFCT subtest than you did on the original ASVAB, the new score replaces the old one for classification purposes. However, if your AFCT score is lower, the higher original score is typically retained. Confirm the current policy with your branch's military personnel office.
