- Rules of the Road and Chart Plot require a 90 passing score; Deck General/Safety and Navigation General require 70.
- On Rules of the Road you can miss only 5 of 50 questions; on Chart Plot only 1 of 17 questions.
- ONC07 totals 160 questions across four separately graded modules, each with a 3.5-hour limit.
- Rules of the Road is closed book with zero references; other modules allow REC-supplied references only.
The OUPV Passing Score Numbers
If you're preparing for the National Operator of Uninspected Passenger Vessel Less Than 100 GRT (OUPV) exam, the single most important number isn't a percentage floating in the abstract - it's four distinct passing scores tied to four separately graded modules. Under the ONC07 exam code (OUPV Near Coastal), the United States Coast Guard's National Maritime Center sets the bar unevenly on purpose:
- Rules of the Road (Q100): 90% required
- Deck General/Safety (Q170): 70% required
- Navigation General: Near Coastal (Q171): 70% required
- Navigation Problems: Chart Plot (Q172): 90% required
Each module is graded independently - passing three modules doesn't offset a failed fourth. For a full breakdown of what content sits inside each of these four areas, see the OUPV Exam Domains 2026: Complete Guide to All 4 Content Areas.
Why the Passing Scores Are Uneven Across Modules
The 90% requirement on Rules of the Road and Chart Plot isn't arbitrary. Both modules test skills where a single wrong answer at sea has immediate collision or grounding consequences: right-of-way determinations, light and sound signal interpretation, and precise plotting of position, course, and speed. The NMC treats these as pass/fail-critical navigation competencies, not general knowledge checks.
Deck General/Safety and Navigation General, by contrast, cover broader operational knowledge - firefighting, stability, aids to navigation, tides, and general seamanship - where a 70% threshold still demands solid mastery but tolerates a wider margin because the content spans more topics with less single-point catastrophic risk.
This distinction matters for how you allocate study time. A candidate who is "pretty good" across all four areas can still fail the exam entirely by falling short on the two 90% modules while comfortably clearing the two 70% ones.
Module-by-Module Breakdown
ONC07 consists of four modules totaling 160 questions, all multiple choice with four answer options. Three of those modules carry 50 questions each - meaning Rules of the Road, Deck General/Safety, and Navigation General together account for roughly 94% of all questions on the exam, with Chart Plot making up the remainder.
Domain 1: Q100 Rules of the Road (31%, 50 questions, 90% to pass)
Closed book, no references permitted at all. Covers Inland and International navigation rules - steering and sailing rules, lights and shapes, sound and light signals, and distress signals.
- Miss no more than 5 of 50 questions
- Memorization must be exact - no reference sheet to fall back on
Domain 2: Q170 Deck General/Safety (31%, 50 questions, 70% to pass)
Covers vessel safety, firefighting, stability, cargo handling basics, and emergency procedures relevant to uninspected passenger vessels.
- Wider margin than Rules of the Road or Chart Plot
- REC-supplied references permitted for this module
Domain 3: Q171 Navigation General: Near Coastal (31%, 50 questions, 70% to pass)
Covers aids to navigation, tides and currents, chart reading, and general navigation principles specific to near-coastal operation.
- Tide Tables, Tidal Current Tables, and Coast Pilot reprints allowed
- Overlaps conceptually with Chart Plot but tests knowledge rather than plotting execution
Domain 4: Q172 Navigation Problems: Chart Plot (6%, 17 questions, 90% to pass)
The smallest module by question count but the least forgiving. Requires actual plotting on training charts using your own dividers, triangles, nautical slide rule, and a non-programmable calculator.
- Miss no more than 1 question out of 17
- Precision in plotting technique matters as much as conceptual understanding
For a topic-by-topic study plan against each of these four modules, the OUPV Study Guide 2026: How to Pass on Your First Attempt walks through prioritization in more depth.
How Much Room for Error You Actually Have
Translating percentages into actual question counts makes the stakes concrete. This is the number candidates underestimate most often when they assume a 90% score is "basically the same difficulty" as a 70% score.
| Module | Questions | Passing Score | Max Questions You Can Miss |
|---|---|---|---|
| Rules of the Road (Q100) | 50 | 90% | 5 |
| Deck General/Safety (Q170) | 50 | 70% | 15 |
| Navigation General (Q171) | 50 | 70% | 15 |
| Chart Plot (Q172) | 17 | 90% | 1 |
That single-question margin on Chart Plot is the number that catches candidates off guard. Because it's only 6% of the exam, some study plans treat it as an afterthought - but a plotting error, a sign mistake, or a misread scale on a training chart can end the module in one move. For a broader picture of where the exam gets genuinely difficult versus where it's manageable, see How Hard Is the OUPV Exam? Complete Difficulty Guide 2026.
Key Takeaway
Treat Chart Plot as a precision skill you drill repeatedly, not a knowledge module you review once - a single missed plot can fail an entire module worth 90% mastery.
Question Format and What References You Can Use
All 160 questions across the four ONC07 modules are multiple choice with four answer options - there's no written response, essay, or short-answer component. Format consistency helps with pacing, since each module carries a three-and-a-half hour limit, but the reference rules differ sharply by module and directly affect how you should prepare.
- Rules of the Road: Closed book. No references, no exceptions. Everything must be memorized cold.
- Deck General/Safety, Navigation General, Chart Plot: REC-supplied references only, including Light List and Coast Pilot reprints, Tide Tables and Tidal Current Tables, training charts, and maneuvering boards/plotting sheets.
- Your own tools: Dividers, triangles, nautical slide rule, and a non-programmable calculator are permitted for plotting work.
Because you cannot bring outside study materials into the testing room, familiarity with the specific format of REC-supplied references (not a personal annotated copy) is something to practice ahead of test day, ideally using the same style of Light List and Tide Tables excerpts you'll see at the Regional Examination Center.
What Happens If You Miss the Passing Score
Passing scores matter twice - once on exam day, and again if you fall short. Under 46 CFR 11.217, the retest policy is module-specific:
- Fail one or two modules: you're allowed two retests within three months, and only on the failed module(s) - you don't retake modules you already passed.
- Fail three or more modules: you must sit a complete re-examination of all four modules, and you'll owe a new examination fee.
This structure rewards a strategy of shoring up your weakest module before test day rather than hoping to average out a shaky module against strong performance elsewhere - since each module's passing score stands alone, there's no averaging to lean on in the first place.
The fee structure itself follows 46 CFR 10.219 Table 1 for an original lower-level officer endorsement: $100 evaluation, $95 examination, and $45 issuance, for a $240 total paid through Pay.gov before your first module. A full failure that triggers complete re-examination means paying the examination fee again.

Scheduling Your Study Around the Passing Thresholds
Since the exam is administered across consecutive business days, your study plan should mirror the graded weight and difficulty ceiling of each module rather than splitting time evenly into quarters. A practical way to sequence preparation in the weeks before your Approval to Test window closes:
Rules of the Road (90% threshold)
- Drill steering/sailing rules, lights, shapes, and sound signals daily until recall is automatic
- Practice under closed-book conditions from day one - no reference crutch to build
Chart Plot (90% threshold, 17 questions)
- Physically practice plotting with dividers, triangles, and a nautical slide rule on training charts
- Time yourself against the 3.5-hour module limit to build plotting speed and accuracy together
Deck General/Safety and Navigation General (70% threshold each)
- Work through safety, stability, and aids-to-navigation content using REC-style reference formats
- Use short, spaced review sessions rather than one long cram - this is the widest-margin content, so consistency beats intensity
This sequencing front-loads the two modules with zero room for error and leaves the wider-margin modules for later, when your overall exam stamina and familiarity with the format are already established. For a general-purpose framework you can adapt to your own timeline, the OUPV Study Guide 2026: How to Pass on Your First Attempt covers pacing in more detail, and running timed sets on our practice test platform is the fastest way to see where your real scores land against these thresholds before test day.
Key Takeaway
Schedule your two 90%-threshold modules - Rules of the Road and Chart Plot - earliest in your prep timeline, since they leave the least margin for a bad week.
Once you understand what score you actually need, it's worth stepping back to confirm the credential itself fits your career goals - see Is the OUPV Certification Worth It?

If you're still confirming eligibility before you even schedule, OUPV Requirements 2026: Eligibility, Prerequisites & How to Qualify covers the sea service, age, TWIC, and medical prerequisites under 46 CFR 11.467 and 11.201. And running full-length timed sessions on our OUPV practice tests before your Approval to Test window opens is the most reliable way to confirm you're consistently clearing 90% on Rules of the Road and Chart Plot, not just hovering near it.
FAQ
It depends on the module. Rules of the Road and Chart Plot each require a 90% passing score, while Deck General/Safety and Navigation General each require 70%. All four modules are graded separately.
Rules of the Road has 50 questions and requires a 90% passing score, meaning you can miss no more than 5 questions and still pass.
Chart Plot has 17 questions and requires a 90% passing score, so you can miss only 1 question and still pass the module.
Rules of the Road is closed book with no references allowed. The other three modules permit REC-supplied references such as Light List and Coast Pilot reprints, Tide Tables and Tidal Current Tables, training charts, and plotting tools you bring yourself, including dividers, triangles, a nautical slide rule, and a non-programmable calculator.
Under 46 CFR 11.217, failing one or two modules allows two retests within three months. Failing three or more modules requires a complete re-examination of all four modules along with a new examination fee.
