- ASTB-E has no published national pass rate - outcomes depend on service-specific stanine and OAR minimums.
- Five of six subtests (MST, RCT, MCT, ANIT, NATFI) are computer-adaptive with no skipping or backtracking.
- You get three lifetime attempts, spaced at least 30 full calendar days apart, and your newest score replaces all prior scores.
- OAR scores range 20-80; AQR, PFAR, and FOFAR composites use 1-9 stanines - minimums vary by service and program.
What "Pass Rate" Really Means for ASTB-E
When people search for an "ASTB-E pass rate," they're usually hoping for a single percentage that tells them how likely they are to succeed. That number doesn't really exist in a usable form for this exam, and here's why: the Aviation Selection Test Battery (ASTB-E) is administered by the Naval Aerospace Medical Institute (NAMI), part of Navy Medicine Operational Training Command, through the APEX testing system for Navy, Marine Corps, and Coast Guard officer aviation selection. Each service - and each program within that service - sets its own minimum composite requirements. A score that clears the bar for one designator may fall short for another.
That means "pass" is not universal. Instead of chasing a mythical percentage, it's more useful to understand exactly how your scores are calculated, which subtests carry the most weight for your target program, and where candidates typically lose points. That's the approach this article takes, and it's the same approach covered in more depth in our ASTB-E Passing Score guide, which breaks down exact composite thresholds by program.
How ASTB-E Scoring Determines Who Moves Forward
ASTB-E produces several separate scores rather than one pass/fail number. The Officer Aptitude Rating (OAR) is reported on a 20-to-80 scale, while the Academic Qualification Rating (AQR), Pilot Flight Aptitude Rating (PFAR), and Flight Officer Flight Aptitude Rating (FOFAR) are reported as stanines from 1 to 9. Each of these composites blends results from the underlying subtests in different proportions, which is why two candidates with similar raw performance can end up with meaningfully different composite outcomes depending on which subtests they excelled in.
Because minimums vary by service branch and by specific aviation program, a candidate applying for a Navy pilot slot and a candidate applying for a Coast Guard aviation program are effectively being measured against different bars using the same test. This is one of the most misunderstood aspects of the exam, and it's why generic "average score" claims floating around online are often misleading. For a full breakdown of how each composite is built from subtest performance, see our ASTB-E Exam Domains guide.
Key Takeaway
Don't study for a single "passing score." Identify the specific OAR and stanine minimums for your target service and program before you build a study plan.
The Six Domains That Drive Your Outcome
Every composite score traces back to performance across six distinct subtests. Understanding what each one actually measures - not just its name - is the fastest way to diagnose where your prep time should go.
Domain 1: Math Skills Test (MST)
Adaptive arithmetic, algebra, and applied word-problem reasoning completed without a calculator.
- Scratch paper and formulas are supplied - memorize how to use them under time pressure
Domain 2: Reading Comprehension Test (RCT)
Short passages followed by adaptive questions testing inference and detail recall.
- No backtracking means you must extract the answer on a single read-through
Domain 3: Mechanical Comprehension Test (MCT)
Physics-based reasoning about levers, gears, pulleys, and basic mechanical systems.
- Visual-spatial reasoning matters as much as formula recall
Domain 4: Aviation and Nautical Information Test (ANIT)
Fact-based knowledge of aerodynamics, aircraft systems, flight rules, and nautical terminology.
- This is the most "learnable" domain since it rewards direct memorization
Domain 5: Naval Aviation Trait Facet Inventory (NATFI)
An adaptive personality and behavioral-trait inventory with no right or wrong answers in the traditional sense.
- Consistency across similarly-worded items matters more than trying to "optimize" answers
Domain 6: Performance Based Measures Battery (PBM)
A hands-on assessment of spatial orientation, dichotic listening, stick-and-throttle tracking, and divided attention.
- This is the only subtest that isn't purely academic - coordination and multitasking under load are being measured directly
For a complete walkthrough of every subtest's format and content, our ASTB-E Exam Domains 2026 guide goes subtest by subtest in more detail than we can cover here.
Why Candidates Struggle - Format and Adaptive Testing Traps
The single biggest surprise for first-time test-takers isn't the content - it's the format. MST, RCT, MCT, ANIT, and NATFI are all computer-adaptive, which means the system adjusts question difficulty based on your responses in real time. Critically, none of these five subtests allow you to skip a question, go back to a previous one, or change an answer once submitted. That rules out common test-taking strategies like flagging hard questions for later or reviewing your work at the end.
This adaptive, no-backtrack structure changes how you should approach pacing. You can't "bank time" on easy questions to spend on hard ones later, because there is no "later." Every question must be answered with full attention the first time you see it. Candidates who are used to linear, paper-style tests often underestimate how disorienting this feels until they've practiced under the same conditions.
The Performance Based Measures Battery (PBM) introduces a completely different challenge: physical and cognitive coordination. Because it tests spatial orientation, dichotic listening, stick-and-throttle tracking, and divided attention simultaneously, it rewards candidates who can genuinely multitask rather than those who are simply academically strong. No amount of flashcard review prepares you for this domain - only repeated, deliberate practice with the specific task types does.
Testing is English-only and administered exclusively at authorized locations, and calculators are prohibited throughout - a detail that trips up candidates who assume the Math Skills Test (MST) allows electronic aids.

Retake Rules and Their Effect on Long-Term Success
ASTB-E allows three lifetime attempts. Between any two attempts, a candidate must wait at least 30 full calendar days. This spacing is intentional - it prevents rapid re-testing based on memorized question patterns and forces genuine additional preparation between sittings.
An important nuance: when you retest, your most recent score replaces all prior scores, not just the previous one. If your first attempt was strong across most domains but weak in one, and your second attempt is worse overall despite improving in that one weak area, the second score is still what counts going forward. This makes the decision to retest a genuinely strategic one - you should only retake the exam if you're confident your overall composite will improve, not just a single subtest.
Conversely, if you never retest, your existing scores remain valid indefinitely and can be used for future applications. This gives strong first-attempt performers real flexibility, since they aren't forced to "use it or lose it" within a narrow window. If you're weighing whether to retest or move forward with an existing score, our Is the ASTB-E Certification Worth It? ROI Analysis article covers how scores factor into longer-term aviation career decisions.
Key Takeaway
Only schedule a retest if your overall composite is likely to improve - a partial improvement in one domain won't help if your replacement score is weaker elsewhere.
Who Is Testing - Service-Specific Score Minimums
Because Navy, Marine Corps, and Coast Guard officer aviation programs each set their own thresholds, the same OAR or stanine result can qualify a candidate for one path and disqualify them from another. The table below summarizes the score types you'll encounter - for exact numeric minimums by program, consult official service guidance and our ASTB-E Requirements guide.
| Score Type | Scale | What It Reflects |
|---|---|---|
| OAR (Officer Aptitude Rating) | 20-80 | General academic aptitude composite |
| AQR (Academic Qualification Rating) | 1-9 stanine | Academic readiness for aviation training |
| PFAR (Pilot Flight Aptitude Rating) | 1-9 stanine | Pilot-track aptitude composite |
| FOFAR (Flight Officer Flight Aptitude Rating) | 1-9 stanine | Flight officer-track aptitude composite |
Because minimums differ by service and by program within each service, two candidates can post identical raw subtest results and still receive different eligibility outcomes. This is also why blanket "average pass rate" figures circulating outside official channels are usually not meaningful - they average across populations with entirely different qualifying bars.

Building a Domain-Focused Prep Timeline
Rather than studying everything at once, sequence your preparation around the format quirks of each domain. Because MST, RCT, MCT, and ANIT are adaptive with no backtracking, early weeks should focus on building raw content fluency before layering on timed, no-review practice conditions.
Math Skills Test (MST) and Reading Comprehension Test (RCT)
- Rebuild core arithmetic and algebra fluency without a calculator
- Practice extracting answers from passages on a single read-through
Mechanical Comprehension Test (MCT) and Aviation and Nautical Information Test (ANIT)
- Review lever, gear, and pulley mechanics with diagrams
- Memorize aerodynamics terms, aircraft systems, and nautical vocabulary
Naval Aviation Trait Facet Inventory (NATFI) and Performance Based Measures Battery (PBM)
- Practice consistent, honest responses to trait-style items
- Drill dichotic listening and stick-and-throttle style coordination tasks
Full-Length, No-Backtrack Simulation
- Take timed practice sessions that mimic the adaptive, no-review format
- Review composite score estimates against your target program's minimums
This kind of structured, domain-sequenced review is covered in far more depth in our ASTB-E Study Guide: How to Pass on Your First Attempt, which includes subtest-specific drills for each week. You can also run full simulated sessions on our practice test platform to get comfortable with the adaptive, no-backtrack format before your official test date.
Once your practice scores stabilize near your target composite, shift remaining time toward the domains where you're closest to the minimum rather than the domains you enjoy studying most. A quick reference of must-know facts across all six domains is available in our ASTB-E Cheat Sheet: One-Page Review of Must-Know Facts, and you can benchmark your readiness against realistic conditions using our full-length practice exams before locking in a test date.
Frequently Asked Questions
No single published pass rate applies to ASTB-E because passing thresholds vary by service branch and by specific aviation program. Success depends on meeting the OAR and stanine minimums for your target program rather than clearing one universal cutoff.
Candidates receive three lifetime attempts, with a mandatory wait of at least 30 full calendar days between attempts. Your most recent score replaces all previous scores when you retest.
No. There is no testing fee for ASTB-E, so the cost of retesting is measured in time and the mandatory 30-day waiting period rather than dollars.
None of the adaptive subtests - Math Skills Test (MST), Reading Comprehension Test (RCT), Mechanical Comprehension Test (MCT), Aviation and Nautical Information Test (ANIT), and Naval Aviation Trait Facet Inventory (NATFI) - allow skipping, backtracking, or answer changes once submitted.
Yes. Existing ASTB-E scores remain valid unless you choose to retest. If you retest, however, the new score set replaces the old one entirely, even if the old scores were stronger in some domains.
Because ASTB-E outcomes hinge on service-specific minimums rather than a single universal benchmark, the most productive way to think about "pass rate" is in terms of your own composite gaps against your target program's requirements. Identify those gaps early, practice under the exact adaptive, no-backtrack conditions you'll face on test day, and use your three lifetime attempts deliberately rather than reactively.
