- National Master 100 NC (NM1N) is governed by the U.S. Coast Guard National Maritime Center, not a private testing vendor with a fixed 2026 calendar.
- The full exam uses five modules: Q100, Q160, Q161, Q162, and Q163.
- You test only after the NMC approves your application, so approval timing drives your real exam date.
- Q165 belongs to the separate OUPV-to-Master raise-of-grade route, not the original five-module exam.
Why the NM1N Has No Fixed Exam Calendar
Search for "NM1N exam dates 2026" and you will probably hope to find a neat list of testing windows, registration cutoffs, and results release dates. That model fits many commercial certifications, but it does not describe how the National Master 100 NC (NM1N) works. This credential is a U.S. Coast Guard Master Near Coastal less-than-100-GRT endorsement, and the examination process sits under the United States Coast Guard National Maritime Center (NMC).
That distinction changes how you should think about "dates." There is no single published 2026 sitting that every candidate targets. Instead, your date is the product of three things: when your application is evaluated and approved, which examination module or modules your route requires, and where you can sit for them. This article walks through each of those pieces so you can build a realistic schedule instead of waiting for a calendar that does not exist.
If you are still deciding whether this endorsement fits your plans, the overview in What Is NM1N? and the eligibility rundown in NM1N Requirements 2026: Eligibility, Prerequisites & How to Qualify are good starting points before you worry about scheduling.
What You Are Actually Scheduling: The Module Structure
The original full-exam pathway for Master Near Coastal less than 100 GRT is built from five modules. Understanding them is the key to understanding your testing plan, because each module is a separate unit you can think about scheduling on its own.
| Module | Domain | Core Subject Matter |
|---|---|---|
| Q100 | Rules of the Road: International and Inland | Watchkeeping, COLREGS, Inland Navigational Rules |
| Q160 | Deck General | Seamanship, marlinspike, vessel handling, firefighting, lifesaving, communications |
| Q161 | Deck Safety | Stability, construction, damage control, emergencies, towing |
| Q162 | Navigation General: Near Coastal | Piloting, compasses, aids to navigation, meteorology, tides and currents |
| Q163 | Navigation Problems: Chart Plot | Chart plotting, fixes, bearing problems, dead reckoning, electronic navigation |
Notice what this table does not contain: percentage weights. Official domain weights are not published in the source material, so any site that quotes exact percentages for these five areas is guessing. Treat the five modules as unweighted, route-aware preparation groups rather than one common mandatory examination that every candidate takes identically.
For a deeper look at what each module covers, see NM1N Exam Domains 2026: Complete Guide to All 5 Content Areas.
Approval to Test Comes Before Any Date
The single most important scheduling fact is sequencing: you test only after the National Maritime Center has approved you to do so. That means the earliest date you can realistically sit for an exam is governed by the application and evaluation process, not by a registration window you can race to beat.
Practically, your timeline looks like this:
- Confirm eligibility. Sea service, documentation, and other prerequisites must be in order. The details are laid out in the requirements guide.
- Submit your application to the NMC. Processing time varies, and it is outside your control once submitted.
- Receive your approval to test. This document specifies the modules you must pass for your particular route.
- Arrange your examination sittings. Only now do actual exam dates enter the picture.
Because the approval step can take time, the smartest move is to begin studying before approval arrives rather than waiting. Your approval letter tells you which modules apply, but the foundational material in the five domains is unlikely to be wasted effort regardless of route.
Key Takeaway
Your "exam date" is downstream of your approval date. If you want to test in a particular season, work backward: allow generous time for application processing, then schedule study around the modules your approval lists.
Which Modules Apply to Your Route
Not every candidate takes all five modules. The published guidance describes different pathways, and these must never be added together into a single universal list. Here is how the main routes differ.
Original Full Exam: Master Near Coastal Less Than 100 GRT
This route uses Q100, Q160, Q161, Q162, and Q163. It is the pathway most people mean when they discuss the National Master 100 NC (NM1N) as a full examination, and it is the structure the rest of this site's preparation material is built around.
Increase in Scope: Great Lakes or Inland to Near Coastal
Mariners who already hold a Great Lakes or inland master endorsement and want to extend to near coastal may face a narrower test. The published guide describes this increase-in-scope route as using Q160 and Q162, with Q100 added where a COLREGS limitation applies to the existing credential. That can mean two or three modules instead of five.
OUPV to Master Near Coastal Raise of Grade
This is a separate pathway. Q165, Navigation and Deck General/Safety, is the raise-of-grade module for candidates moving from an OUPV to Master Near Coastal less than 100 GRT. It is not part of the original five-module exam, and it should not be added to that list. If your approval mentions Q165, you are on this route, and your preparation should reflect that.
| Route | Modules | Notes |
|---|---|---|
| Original full exam (Master NC <100 GRT) | Q100, Q160, Q161, Q162, Q163 | The five-domain structure used on this site |
| Increase in scope (GL/Inland to NC) | Q160 + Q162 | Add Q100 if a COLREGS limitation applies |
| OUPV to Master NC <100 GRT raise of grade | Q165 | Separate module; not part of the original five |
Because these pathways differ, no honest article can give you one number for "how many exams" or "how long testing takes." Your approval to test is the authority. If cost planning is on your mind, remember the same caution applies to fees: there are no universal fee figures or timers to quote, so check NM1N Certification Cost 2026: Complete Pricing Breakdown for how to think about expenses without relying on invented numbers.
Sequencing Modules Across Your Testing Plan
When your route includes multiple modules, the order in which you tackle them is a strategic choice. A few considerations specific to this credential:
Start with Q100: Rules of the Road
The Rules of the Road module is the foundation that other deck and navigation thinking leans on. Watchkeeping, COLREGS, and the Inland Navigational Rules reward precise memorization of wording, which makes it a good early module for building momentum.
- International versus Inland rule distinctions
- Watchkeeping responsibilities
- Light, shape, and sound signal recognition
Group Q160 and Q161 Together
Deck General and Deck Safety overlap heavily. Fire prevention and firefighting, abandon ship procedures, rescuing survivors, vessel power plants, and small engine operations appear in both published topic lists. Studying them as a pair avoids relearning shared material.
- Q160 adds seamanship, marlinspike, maneuvering, communications, and lifesaving appliance operation
- Q161 adds stability, trim, construction, damage control, man overboard, and emergency towing
Pair Q162 and Q163 for Navigation
General navigation theory (Q162) and chart plotting (Q163) feed each other. Piloting, distance off, bearing problems, fixes and running fixes, dead reckoning, and aids to navigation appear in both. Q162 adds compass error, meteorology, and tides and currents; Q163 adds electronic navigation and applied plotting.
- Practice plotting by hand, not just reading about it
- Treat compass error as its own sub-skill
The chart plotting module is often the one candidates find most demanding because it tests applied technique rather than recall. For a candid look at where difficulty tends to concentrate, read How Hard Is the NM1N Exam? Complete Difficulty Guide 2026.
Deadlines That Actually Matter
Since there is no universal 2026 registration calendar, the deadlines that matter to you are the ones attached to your own paperwork. Think of them in these categories:
- Application validity. An NMC approval to test is not open-ended. Check your approval documentation for any expiration or time limit on testing, and plan so you are not caught short.
- Retake rules. If you fail a module, the rules governing when and how you may retest apply to your situation. Review them before your first attempt so you know what a miss would cost in time.
- Credential renewal cycles. Passing the exam is one step toward the endorsement; your overall credential has its own administrative timeline separate from the exam.
- Personal constraints. Seasonal work, sea service rotations, and charter schedules often matter more to your real timeline than any official window.
Questions about how results translate to passing are covered in NM1N Passing Score 2026: Exactly What You Need to Pass, and you can see what outcome data does and does not exist in NM1N Pass Rate 2026: What the Data Shows.
A Domain-Ordered Preparation Timeline
Because your testing date depends on approval, the best use of waiting time is a domain-ordered study plan. The sequence below follows the logic of the five modules and can be compressed or stretched to fit your route. Adjust it if your approval lists fewer modules.
Q100 Rules of the Road
- Learn International and Inland rules side by side, noting where they diverge
- Drill signals, lights, and shapes until recognition is automatic
- Review watchkeeping principles
Q160 Deck General
- Seamanship, marlinspike, blocks and tackle, and temporary repairs
- Vessel maneuvering: turn circle, pivot point, advance and transfer, wake reduction
- Communications, certificates and documents, and lifesaving appliance operation
Q161 Deck Safety
- Trim and stability, construction, and damage control
- Fire prevention, firefighting appliances, and emergency procedures
- Man overboard procedures and emergency towing
Q162 and Q163 Navigation
- Compass error determination, aids to navigation, charts and Notices to Mariners
- Meteorology, tides, and tidal currents
- Daily chart plotting: fixes, running fixes, distance off, and dead reckoning
This is a template, not a guarantee, and it is the only generic scheduling element in this article. The reasoning behind the order is simple: rules knowledge underpins everything else, the two deck modules share overlapping content, and the two navigation modules reward steady hands-on plotting practice. For fuller methodology, the NM1N Study Guide 2026: How to Pass on Your First Attempt goes deeper, and the NM1N Cheat Sheet 2026: One-Page Review of Must-Know Facts is useful for last-week review.
To test your readiness against realistic question styles as your approval comes through, work through the practice questions at the main NM1N practice test site.
What to Expect When a Module Date Arrives
Once you have approval and a scheduled sitting, preparation shifts from content to execution. Keep these module-specific realities in mind:
- Q100 and Q160/Q161 lean on knowledge recall and scenario recognition. Read each question stem carefully, especially where International versus Inland rules could produce different answers.
- Q162 blends theory and calculation, with compass correction and tidal problems demanding careful, step-by-step work.
- Q163 is applied plotting. Bring the habit of checking your work: a small error in a bearing or time can carry through to a wrong position.
Arrive with your approval documentation in order and confirm in advance which modules you are attempting at each sitting. Mixing up route-specific modules, such as walking in prepared for the five-module exam when your approval lists the narrower increase-in-scope set, is an avoidable and costly mistake.
Key Takeaway
Before any sitting, reread your approval to test and confirm the exact module codes listed. Your route, not a generic checklist, defines what you will be examined on.

Frequently Asked Questions
No single universal 2026 calendar governs this credential. The U.S. Coast Guard National Maritime Center oversees the process, and your actual testing date depends on when you receive approval to test and when you arrange your sittings for the modules your route requires.
The original Master Near Coastal less-than-100-GRT full exam uses five modules: Q100 (Rules of the Road), Q160 (Deck General), Q161 (Deck Safety), Q162 (Navigation General: Near Coastal), and Q163 (Navigation Problems: Chart Plot).
Q165, Navigation and Deck General/Safety, is a separate module for the OUPV-to-Master Near Coastal less-than-100 raise-of-grade route. It is not part of the original five-module exam and should not be added to it.
Not necessarily. The published increase-in-scope route from Great Lakes or inland to near coastal uses Q160 and Q162, with Q100 added where a COLREGS limitation applies. Your approval to test confirms exactly which modules you need.
Yes, and it is usually wise to. Approval timing is outside your control, and the five domains cover foundational mariner knowledge. Begin with the modules most likely to apply, then refine once your approval confirms your route.
No universal fee or timer figures should be assumed, because they can differ by route and circumstance. Confirm current details through the National Maritime Center and your own approval paperwork rather than relying on a generic number.
