- The OAR reports scores on a 20-80 scale, and most examinees land between 40 and 60.
- There is no universal "passing score" - each officer community sets its own minimum.
- Candidates get up to three attempts on the current ASTB-E version, with a mandatory 30-day wait between tries.
- All three subtests - Math Skills, Reading Comprehension, and Mechanical Comprehension - are computer-adaptive.
Why There's No Single Published OAR Pass Rate
If you searched for "OAR pass rate" expecting one clean percentage, here's the honest answer: the Officer Aptitude Rating doesn't work that way. The OAR is the three-subtest academic core of the ASTB-E, administered by the Naval Aerospace Medical Institute's Operational Psychology department, and it functions as a selection assessment rather than a pass/fail licensing exam. There's no central body publishing an annual "X% passed" statistic the way you might see for a standardized certification.
Instead, what determines whether your score is "good enough" is the officer community, or designator, you're pursuing. Each community - surface warfare, intelligence, supply corps, and others - sets its own minimum composite standards, and those standards are reviewed and adjusted through current program authorizations. A score that clears the bar for one designator may fall short for a more competitive one. That's why the most useful way to think about your outcome isn't a mythical pass rate, but where your score falls on the reported scale relative to the standard your target community actually requires.
How OAR Scores Are Reported
The OAR reports results on a 20-80 scale, scored in one-point increments. Most examinees score somewhere between 40 and 60, which gives you a rough sense of where the bulk of the testing population lands. Scoring above that range puts you in a smaller, more competitive tier; scoring below it may limit which designators you qualify for, depending on current standards.
Because the scale spans 20 to 80 with most people clustering in the middle third, small improvements in your raw performance can move you meaningfully within that middle band - which is exactly where competitive separation happens for many designators. This is one reason a structured OAR Study Guide 2026: How to Pass on Your First Attempt approach matters more than it might for a simple pass/fail test: you're not just clearing a bar, you're trying to position your score as high as possible within a known range.
For a deeper breakdown of exactly what score you should be targeting based on current designator guidance, see our dedicated piece on the OAR Passing Score 2026: Exactly What You Need to Pass.
The Three Domains Behind Every Score
Your OAR score is built from three computer-adaptive subtests. Because performance on each section adjusts item-by-item to your responses, understanding what each domain actually tests is more valuable than memorizing generic test-taking tricks.
Domain 1: Math Skills Test (MST)
Covers arithmetic, algebra, and applied word problems. Calculators are prohibited, but relevant formulas and scratch paper are provided at the testing station.
- Speed with mental arithmetic and fraction/decimal conversion
- Algebraic manipulation without calculator support
- Translating word problems into solvable equations quickly
Domain 2: Reading Comprehension Test (RCT)
Presents passages followed by questions on main idea, inference, and detail retrieval - all in English, with no ability to revisit or change adaptive items once answered.
- Efficient first-pass reading for structure and argument
- Distinguishing directly stated facts from inferred conclusions
- Managing time since skipped or revisited items aren't allowed
Domain 3: Mechanical Comprehension Test (MCT)
Tests understanding of basic physics and mechanical systems - levers, gears, pulleys, fluid dynamics, and simple machines.
- Core mechanical advantage and force/torque relationships
- Reading diagrams of gears, pulleys, and inclined planes accurately
- Applying formulas provided at the station rather than recalling them from scratch
For a full walkthrough of each subtest's content and question style, see the OAR Exam Domains 2026: Complete Guide to All 3 Content Areas. If you're still weighing how demanding the exam is overall relative to your background, our How Hard Is the OAR Exam? Complete Difficulty Guide 2026 breaks that down subtest by subtest.
How Officer Communities Set Their Own Standards
Because the Navy lets individual officer communities set their own selection standards, two candidates with identical OAR scores can have very different outcomes depending on which designator they're pursuing. This is a structural feature of the program, not an inconsistency - it lets each community calibrate its academic bar to the demands of that specific officer track.
Practically, this means generic "average score" data is less useful to you than the specific current program authorization for your target designator. Recruiters and program administrators have access to the most current standards, and those figures can shift between testing cycles.
| Factor | What It Means for You |
|---|---|
| Score scale | 20-80, one-point increments; most examinees score 40-60 |
| Passing standard | Set individually by each officer community/designator |
| Test fee | None - scheduled through a recruiter or program administrator |
| Attempts allowed | Up to three on the current ASTB-E version |
| Retest wait | 30 full calendar days between attempts |
Key Takeaway
Don't chase a generic benchmark. Confirm the exact minimum standard for your designator through your recruiter before you decide whether a retake is worth pursuing.
Attempt Limits and the 30-Day Wait
The Navy caps candidates at three attempts on the current version of the ASTB-E, and requires a full 30 calendar days between each attempt. This is a meaningful constraint: it means you can't simply retest the following week to shake off a bad testing day, and it means your preparation before attempt one carries outsized weight.
Equally important, existing scores remain valid unless you choose to retest. There's no automatic expiration pushing you to retake the exam on a schedule - the decision to retest is entirely about whether your current score meets the standard you need. That said, retesting resets the clock on your three-attempt ceiling, so it's worth treating every attempt as if it might be your best shot.
If you're mapping out when to schedule your test relative to application deadlines or officer program cycles, check the OAR Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide before locking in a date with your recruiter.
Why the Adaptive Format Changes the Math
All three OAR subtests - Math Skills, Reading Comprehension, and Mechanical Comprehension - are computer-adaptive, delivered through the Navy's APEX system. That means the number of items and their difficulty adjust in real time based on your responses. Official completion time runs 1 to 2 hours total, but your exact experience will differ from another candidate's because the test is responding to you specifically.
The practical consequence: adaptive items cannot be skipped, revisited, or changed once answered. There's no strategy of "skip the hard ones and come back." Every question demands a committed answer before you move forward, which puts a premium on steady pacing over the whole session rather than saving time for a final review pass.
A Domain-Based Prep Timeline
Rather than a generic study calendar, sequence your prep around the structural realities of the OAR: no calculator, adaptive delivery, and no ability to revisit answered items. That changes which skills need automatic recall versus which just need familiarity.
Math Skills Foundations
- Drill mental arithmetic and fraction/decimal conversions without a calculator
- Practice translating word problems into equations under time pressure
Reading Comprehension Pacing
- Practice single-pass reading for main idea and structure
- Simulate no-revisit conditions so you commit to answers and move on
Mechanical Comprehension Concepts
- Review gears, pulleys, levers, and basic force/torque relationships
- Practice applying provided formulas quickly rather than memorizing derivations
Full Simulation
- Take timed, adaptive-style practice sessions across all three domains
- Review weak areas identified across MST, RCT, and MCT before test day
For structured practice sets that mirror the adaptive, no-revisit format across all three domains, our practice test platform is built specifically around the OAR's actual question style rather than generic aptitude questions. You can also pair timed drills from the practice test platform with the checklist in the OAR Cheat Sheet 2026: One-Page Review of Must-Know Facts for a fast pre-test review.
Who Actually Sits for the OAR
Not every officer candidate takes the full ASTB-E. Aviation applicants sit for the complete battery, while many non-aviation officer applicants take only the OAR - the Math Skills, Reading Comprehension, and Mechanical Comprehension core. This distinction matters when you're benchmarking your prep: if you're pursuing a non-aviation designator, your entire testing experience is these three subtests, with no additional aviation-specific sections to worry about.
If you're still early in figuring out eligibility, scheduling logistics, or how the OAR fits into your officer program application, our guides on OAR Requirements 2026: Eligibility, Prerequisites & How to Qualify and What Is OAR? cover the fundamentals before you get to scheduling.

Frequently Asked Questions
No single pass rate is published. Because officer communities set their own minimum score standards, "passing" depends entirely on the designator you're pursuing, not a fixed universal threshold.
Scores are reported on a 20-80 scale, with most examinees scoring 40-60. Your specific target should come from the current program authorization for the designator you want, via your recruiter or program administrator.
Candidates get up to three attempts on the current version of the ASTB-E, with a required 30 full calendar days between each attempt.
No. Existing scores remain valid unless you choose to retest. There is no automatic expiration date forcing a retake.
All candidates take the Math Skills, Reading Comprehension, and Mechanical Comprehension subtests, but because delivery is computer-adaptive, item count and difficulty vary by candidate performance in real time.
