- OAR scores are reported on a 20-80 scale in one-point increments, not a percentage or pass/fail flag.
- Most examinees score between 40 and 60, but there is no single universal "passing" number.
- Each officer community sets its own minimum OAR standard, so the score you need depends on your designator.
- You get no more than three attempts on the current ASTB-E version, with a mandatory 30-day wait between tries.
How OAR Scoring Actually Works
The Officer Aptitude Rating (OAR) is the academic core of the ASTB-E battery, administered by the U.S. Navy through the Naval Aerospace Medical Institute's Operational Psychology department. Unlike a certification exam with a fixed cut score printed on a scorecard, the OAR reports results on a 20-80 scale, in one-point increments. There is no percentage, no letter grade, and no universal "passing line" published for every applicant.
That single fact trips up a lot of candidates who search for "OAR passing score" expecting a clean number. The reality is more nuanced: your raw performance on the Math Skills Test, Reading Comprehension Test, and Mechanical Comprehension Test converts into a scaled score, and that scaled score is then evaluated against whatever minimum the officer community you're applying to has set. If you're still getting oriented to the exam itself, the What Is OAR? overview and the OAR Meaning explainer are good starting points before you dig into scoring mechanics.
What Counts as a "Passing" Score
Because officer communities set their own selection standards, the honest answer to "what score do I need" is: it depends on the designator you're pursuing. The Navy does not publish one fixed minimum OAR score for every commission path. Instead, each community - surface warfare, intelligence, supply corps, and others that don't require the full ASTB-E - establishes its own program authorization with its own minimum.
This means two applicants can take the identical exam, score identically, and have completely different outcomes depending on which designator they're pursuing. Practically, that means your prep strategy should start with a simple question: what score does my target program actually require? Your recruiter or officer program administrator holds the current program authorization and can tell you the specific number tied to your designator.
Key Takeaway
Don't study toward a generic "good score." Ask your recruiter or program administrator for the current minimum tied to your specific designator, then build your prep plan around that actual number.

The Three Subtests That Determine Your Score
Your OAR score is a composite reflection of performance across three subtests. Each one draws on a distinct skill set, and weaknesses in any single area can pull your overall scaled score down.
Domain 1: Math Skills Test (MST)
Covers arithmetic reasoning, algebra, and problem-solving without a calculator. Since calculators are prohibited on the OAR, mental math fluency and estimation skills matter as much as knowing the formulas.
- Practice long-form arithmetic and fraction/decimal conversions by hand
- Work through algebraic word problems under time pressure
- Get comfortable with the reference formulas provided during the test
Domain 2: Reading Comprehension Test (RCT)
Measures your ability to extract main ideas, inferences, and details from passages presented entirely in English. Speed and precision both matter since adaptive items cannot be revisited once answered.
- Practice identifying the author's main point quickly
- Train yourself to answer from the passage, not prior knowledge
- Build stamina for sustained reading focus during the 1-2 hour session
Domain 3: Mechanical Comprehension Test (MCT)
Tests understanding of basic physics and mechanical principles - gears, pulleys, levers, force, and motion. This is often the least familiar domain for candidates without a technical background.
- Review fundamental mechanical concepts and how simple machines behave
- Practice interpreting diagrams quickly since visuals drive most items
- Memorize the handful of core mechanical relationships tested repeatedly

Why Your Target Designator Changes the Target Number
It's worth repeating because it's the single most misunderstood part of OAR scoring: this is not a one-size-fits-all exam with a fixed cutoff. Aviation applicants sit for the full ASTB-E, which includes the OAR plus additional aviation-specific sections, while many non-aviation officer applicants take only the OAR portion. That structural difference already tells you the exam experience - and the standard you're held to - varies by career path.
| Factor | Aviation Applicants | Many Non-Aviation Applicants |
|---|---|---|
| Test taken | Full ASTB-E (includes OAR) | OAR only |
| Scaled score range | 20-80 | 20-80 |
| Minimum required score | Set by aviation program authorization | Set by the specific officer community's authorization |
| Test fee | None | None |
How the Adaptive Format Affects Your Score
All three OAR subtests - Math Skills, Reading Comprehension, and Mechanical Comprehension - are computer-adaptive and delivered through the Navy's APEX testing system at military testing locations. That has direct implications for how your score is built and how you should approach the session:
- Item count and difficulty adjust to you. Because the number of questions and their difficulty depend on how you're performing, there's no fixed "passing number of correct answers" to chase - the scaled score already accounts for the difficulty of what you answered.
- You cannot skip, revisit, or change adaptive items. Once you commit to an answer, it's locked in. This makes careless early mistakes more costly than on a traditional fixed-form exam, so pacing yourself carefully from the very first question matters.
- The exam is English-only, and while calculators are prohibited, relevant formulas and scratch paper are provided at the testing location, so you don't need to memorize every formula - just know how to apply them quickly.
- Official completion time is 1 to 2 hours across all three subtests, so managing your pace within that window is part of protecting your scaled score.
Understanding this adaptive structure is one reason a general study approach doesn't work well for the OAR - you need domain-specific practice under realistic, no-skip conditions. The OAR Study Guide 2026: How to Pass on Your First Attempt walks through how to simulate that adaptive pressure during prep, and running full-length practice sessions on our practice test platform is one of the more direct ways to get used to answering under those locked-in conditions before test day.
Retake Rules and What Happens to Old Scores
Because the OAR is a selection assessment rather than a renewable credential, there's no expiration date to track - but there are firm limits on how many chances you get to hit your target score.
- Examinees receive no more than three attempts at the current version of the ASTB-E.
- You must wait a full 30 calendar days between attempts.
- Existing scores remain valid unless you choose to retest - so a strong score doesn't disappear just because time has passed.
Key Takeaway
If your first attempt lands below your designator's minimum, use the mandatory 30-day gap deliberately. Identify which of the three domains cost you the most points and concentrate your remaining prep time there rather than reviewing everything equally.
Because retakes are capped at three and spaced a month apart, treating your first attempt casually is risky. It's worth reviewing how the retake structure interacts with overall exam difficulty in OAR Pass Rate 2026: What the Data Shows before you schedule your first sitting through your recruiter.
A Domain-Focused Prep Timeline
Since there's no test fee and scheduling runs through your recruiter or program administrator rather than a public registration portal, your prep timeline should be built around the 30-day retake window and the three-domain structure, not around a generic study calendar. Here's one way to sequence it if you're starting from scratch:
Math Skills Test Foundations
- Rebuild calculator-free arithmetic and algebra fluency
- Time yourself on word problems to build speed without shortcuts
Reading Comprehension Test Drills
- Practice full passages under a strict per-question pace
- Focus on main-idea and inference questions, the most common trap types
Mechanical Comprehension Test Review
- Study core simple-machine and force concepts if you lack a technical background
- Drill diagram-based questions since visuals dominate this subtest
Full-Length, No-Skip Practice
- Run complete practice sessions that mimic the locked-answer adaptive format
- Review missed items by domain to spot which subtest still needs work
This structure works because it mirrors the actual exam composition rather than borrowing a generic weekly template.

Test-Day Logistics That Protect Your Score
A few procedural details matter more than most candidates realize, because a preventable mistake at check-in can cost you a scheduled attempt entirely:
- Bring photo identification plus Social Security number verification. Missing documentation at a military testing location can derail an attempt you scheduled through your recruiter.
- The exam is delivered in APEX at official military testing sites - you cannot take it remotely or through a third-party testing center.
- Calculators are prohibited, but relevant formulas and scratch paper are supplied, so don't bring your own reference materials.
- Adaptive items lock in immediately - there's no reviewing your work at the end, so pace deliberately from question one.
These logistics matter just as much as content knowledge, since even a well-prepared candidate can lose an attempt to an avoidable scheduling or documentation error. If you're still mapping out timing around your application, OAR Exam Dates 2026: Testing Windows, Deadlines & Scheduling covers how scheduling through a recruiter typically works, and OAR Cheat Sheet 2026: One-Page Review of Must-Know Facts is a quick reference for the exam-day rules covered here.
FAQ: OAR Passing Score
No. The OAR is scored on a 20-80 scale, but each officer community sets its own minimum standard for the designator it's recruiting for. Check with your recruiter or program administrator for the exact number tied to your target path.
Most examinees score between 40 and 60 on the 20-80 scale. That's a general clustering range, not a pass/fail benchmark - your actual requirement depends on your designator.
Examinees get no more than three attempts at the current ASTB-E version, with a mandatory 30 full calendar days between attempts. Existing scores stay valid unless you choose to retest.
The Math Skills Test, Reading Comprehension Test, and Mechanical Comprehension Test are each computer-adaptive and contribute to your overall academic profile. Since each is scored independently and reviewed by program authorizations, weakness in any one subtest can affect your eligibility for a given designator.
The OAR is a selection assessment rather than a renewable credential, and existing scores remain valid unless you choose to retest. There's no fixed expiration built into the scoring system itself.
