- OAR is scored 20-80; AQR, PFAR, and FOFAR use 1-9 stanines, and minimums differ by service and program.
- There is no single universal "passing score" - your target composite depends on the pipeline you're applying to.
- Five subtests (MST, RCT, MCT, ANIT, NATFI) are computer-adaptive with no skipping, backtracking, or answer changes.
- You get three lifetime attempts with a mandatory 30 full calendar days between attempts.
How ASTB-E Scoring Actually Works
The Aviation Selection Test Battery (ASTB-E) doesn't hand you a single pass/fail number the way a licensing exam might. Instead, the Naval Aerospace Medical Institute (NAMI), part of Navy Medicine Operational Training Command, produces several composite scores from your performance across the six subtests. Those composites are then compared against separate minimum thresholds set by the Navy, Marine Corps, and Coast Guard for their specific aviation programs. In other words, "passing" the ASTB-E is really about clearing the composite floor required for the pipeline you're pursuing - not hitting one fixed number that applies to everyone.
This matters enormously for how you prepare. If you're chasing a Navy pilot slot versus a Coast Guard aviation program, the composite you need to protect most closely can differ. Before you build a study plan, confirm the exact minimums for your target program with your recruiter or officer programs coordinator, then work backward from there. For a broader orientation to what the exam covers and why it's structured this way, our What Is ASTB-E? overview is a good starting point.
The Four Composite Scores Explained
Your raw subtest performance is converted into four composite scores. Understanding what feeds each one helps you know exactly where to focus your energy.
OAR - Officer Aptitude Rating
The OAR draws from the Math Skills Test (MST) and Reading Comprehension Test (RCT). It's scored on a 20-to-80 scale and is the composite most often referenced when people talk about qualifying for officer commissioning programs broadly, separate from aviation-specific selection.
- Built from quantitative and verbal comprehension performance
- Can be taken as a standalone OAR-only session in roughly 1 to 2 hours
AQR - Academic Qualification Rating
The AQR incorporates additional subtest information beyond the OAR to gauge academic readiness for aviation training pipelines. It's reported on the 1-to-9 stanine scale used for the three non-OAR composites.
PFAR - Pilot Flight Aptitude Rating
PFAR blends mechanical, aviation/nautical knowledge, and other performance data to estimate readiness specifically for pilot training tracks. This is frequently the composite pilot-track candidates should scrutinize most closely.
FOFAR - Flight Officer Flight Aptitude Rating
FOFAR serves a parallel purpose for flight officer/naval flight officer tracks rather than pilot tracks, drawing on a different weighting of the same underlying subtest data.
Because AQR, PFAR, and FOFAR all sit on the 1-to-9 stanine scale, small differences in raw performance can shift a stanine more than you'd expect near the boundaries. That's one reason candidates benefit from working through the full mechanics of each subtest in our ASTB-E Exam Domains Guide rather than studying generically.
Why There's No Single "Passing Score"
It's worth repeating because it trips up so many candidates: the ASTB-E does not have one universal cut score. NAMI administers the battery and generates your composites, but each service - Navy, Marine Corps, Coast Guard - sets its own minimums for its own aviation programs, and those minimums can also vary by the specific pipeline (pilot versus flight officer, for example) within a service.
Key Takeaway
Treat "what score do I need" as a question with a program-specific answer. Get your target composite minimums in writing or from an authoritative source tied to your intended pipeline before you finalize a study plan.
This also means two candidates can take the exact same test and walk away with genuinely different "passing" outcomes depending on what they applied for. If you're still weighing whether pursuing this path is worthwhile given the effort involved, our Is the ASTB-E Certification Worth It? analysis and the ASTB-E Salary Guide can help frame the decision before you commit study hours to a specific composite target.
How Each Subtest Feeds Your Composites
Since your composites are built from subtest performance, improving a specific composite means understanding exactly what that subtest tests - and how it's delivered. All ASTB-E content is administered in English only, at authorized testing locations, through the Navy's APEX system.
Domain 1: Math Skills Test (MST)
Feeds directly into your OAR. Covers arithmetic, algebra, and geometry reasoning under a computer-adaptive format.
- No calculators permitted - mental math and estimation matter
- Formulas and scratch paper are supplied, so you don't need to memorize every formula
Domain 2: Reading Comprehension Test (RCT)
Also feeds the OAR. Tests your ability to extract main ideas, inferences, and details from passages under adaptive, non-backtracking conditions.
- Once you answer, you cannot return to change it
- Pacing discipline matters more here than on paper-based reading tests
Domain 3: Mechanical Comprehension Test (MCT)
Feeds into PFAR most heavily. Covers basic physics and mechanical systems - levers, gears, pulleys, fluid dynamics, and simple machines.
- Candidates without a mechanical/engineering background often need the most dedicated review here
Domain 4: Aviation and Nautical Information Test (ANIT)
Feeds PFAR and FOFAR. Covers aviation terminology, aerodynamics basics, flight rules concepts, and nautical/naval knowledge.
- This is largely a knowledge-recall domain - prior exposure to aviation or Navy/Marine/Coast Guard terminology helps
Domain 5: Naval Aviation Trait Facet Inventory (NATFI)
A personality/trait inventory rather than a knowledge test. It's computer-adaptive like the others but is measuring behavioral tendencies relevant to aviation service, not "right or wrong" academic answers.
- There's no cramming for this - respond honestly and consistently
Domain 6: Performance Based Measures Battery (PBM)
Measures spatial orientation, dichotic listening, stick-and-throttle tracking, and divided attention - skills closer to simulator performance than academic testing.
- Practice with basic hand-eye coordination and divided-attention tasks can help you get comfortable with the format
- Unlike the other five subtests, this is a hands-on performance measure rather than a question-and-answer format
For a deeper breakdown of question styles and pacing inside each of these six areas, see the full ASTB-E Exam Domains Guide. If you're trying to gauge overall difficulty before you commit to a timeline, How Hard Is the ASTB-E Exam? breaks down where most candidates struggle.
Test Format, Fees, and Retake Rules
A few structural facts directly affect how you should plan your attempt - and they're often misunderstood.
| Item | Detail |
|---|---|
| Administering body | Naval Aerospace Medical Institute (NAMI), Navy Medicine Operational Training Command |
| Testing fee | None |
| Full six-subtest battery duration | Approximately 2 hours to 3 hours 15 minutes |
| OAR-only session duration | Approximately 1 to 2 hours |
| Adaptive subtests | MST, RCT, MCT, ANIT, NATFI (no skipping, backtracking, or answer changes) |
| Lifetime attempts | Three |
| Minimum gap between attempts | 30 full calendar days |
| Score retention policy | Most recent scores replace all prior scores; existing scores stay valid unless you retest |
Because there's no testing fee, cost planning for ASTB-E prep looks different than for many other certification exams - your investment is almost entirely time and study materials, not registration expense. If you want the full picture on where money does or doesn't factor in, see ASTB-E Certification Cost.
Before you schedule anything, make sure you actually meet the baseline eligibility for testing in the first place - age, citizenship, and program-specific prerequisites are covered in ASTB-E Requirements, and current testing windows are outlined in ASTB-E Exam Dates.
A Domain-by-Domain Plan to Raise Your Composites
Since composites are built from specific subtest pairings, the most efficient prep sequences your study time around which composite you're protecting, not around generic "study more" advice.
OAR Foundation (MST + RCT)
- Rebuild core arithmetic, algebra, and geometry fluency without relying on a calculator
- Practice timed reading passages to build pacing under adaptive, no-backtrack conditions
PFAR/FOFAR Foundation (MCT + ANIT)
- Review basic mechanical principles: levers, gears, pulleys, and fluid systems
- Study aviation terminology and nautical/naval knowledge relevant to ANIT
NATFI Familiarization
- Understand the trait-inventory format so the style doesn't surprise you on test day
- Focus on honest, consistent self-assessment rather than trying to "optimize" answers
PBM Practice and Full Simulation
- Practice divided-attention and hand-eye coordination tasks similar to stick-and-throttle tracking
- Run a full-length timed simulation covering all six domains back to back
This kind of structured, domain-anchored schedule is far more useful than generic weekly templates because it maps directly to the composite scores that determine your outcome. For a complete walkthrough of building this into a full prep plan, see our ASTB-E Study Guide. And if you want a fast, condensed reference to keep nearby in the final days before your test, the ASTB-E Cheat Sheet summarizes the must-know facts across all six domains.
Once you've worked through content review, timed practice on realistic questions is what actually reveals whether your composite estimates are on track. You can run full-length practice sessions on our practice test platform to simulate the adaptive, no-backtrack pressure you'll face on test day, and repeat targeted drills on the same practice site for whichever domain is dragging your weakest composite down.
Key Takeaway
Don't study for "the ASTB-E" as one undifferentiated exam. Study for the specific composite (OAR, AQR, PFAR, or FOFAR) tied to your target program, and let that composite dictate which of the six domains gets the most hours.
FAQ
There isn't one universal passing score. NAMI generates OAR (20-80 scale) and AQR, PFAR, FOFAR (1-9 stanine scale) composites, and each service sets its own minimums by program. Confirm your specific target with your service's aviation program requirements.
OAR is built from the Math Skills Test and Reading Comprehension Test and reported on a 20-to-80 scale. AQR, PFAR, and FOFAR draw on a broader combination of subtests and are reported as 1-to-9 stanines, each geared toward a different program track.
Yes, you have three lifetime attempts with a required 30 full calendar days between attempts. Your most recent scores replace all prior scores entirely, so retest only after you've addressed the specific domain that limited your composite.
No. There is no testing fee for the Aviation Selection Test Battery. Your preparation investment is in study time and materials rather than registration costs.
No, calculators are prohibited on the MST. Necessary formulas and scratch paper are supplied at the testing location, so preparation should focus on mental math fluency and formula application rather than formula memorization.
