NFCP Exam Domains 2026: Complete Guide to All 6 Content Areas

Why the Six Domains Are Route-Aware

National First Class Pilot (NFCP) candidates are examined under the United States Coast Guard National Maritime Center (NMC) examination structure for the FCP01 exam group. If you are used to certifications with a single blueprint, one question count and a fixed set of weighted domains, this one works differently. The NMC Examination Guide organizes the First Class Pilot exam as a set of modules, and which modules you sit depends on your route and your circumstances.

That is why we describe the content as six route-aware preparation groups rather than seven required subjects. If you counted every module code in the published catalog, you would find more than six, but the two Rules alternatives (Q100 and Q300) are never both required, and the two chart-plot alternatives (Q372 and Q373) are never both required either. Section 2.1.2.4 of the published guide calls for one Rules module and one chart-plot module, chosen by route. Folding those alternatives together gives six groups you actually have to prepare for.

For a broader orientation to the credential itself, see What Is NFCP? and NFCP Requirements 2026: Eligibility, Prerequisites & How to Qualify. This article focuses on what you will actually be tested on.

Domain 1: Rules of the Road (Q100 or Q300)

The Rules module is the first thing to settle, because the route you hold or seek determines which version you sit. Q100 covers Rules of the Road: International and Inland, while Q300 covers Inland only. You are never asked to prepare for both as a single requirement.

For a pilot, this is not rote memorization. Expect to apply the rules to situations: who gives way, what signals apply, and how the rules change at the boundary between inland and international waters. Candidates on inland-only routes should confirm they are scheduled for the Inland module and focus their effort there, instead of splitting time across rule sets they will not be tested on.

Domain 2: Deck General/Safety (Q370)

Deck General/Safety is the broadest practical module and the one most tied to hands-on seamanship. The NMC topic catalog groups it into seamanship, vessel handling, firefighting and maritime law.

Because this module spans so many sub-topics, candidates often underestimate it. Interaction effects, such as bank effect and passing-ship interaction, and the relationship between pivot point, advance and transfer are the kind of concept-heavy topics that reward understanding over memorization.

Domain 3: Navigation General (Q371)

Navigation General is the theory-heavy counterpart to the chart-plot module. It covers the concepts and regulations behind safe navigation, and it has the longest topic list in the catalog.

Position, Piloting and Chart Work Concepts

• Navigation and position determination, including estimated time of arrival
• Piloting, distance off, bearing problems, and fix or running fix
• Chart navigation and dead reckoning
• Electronic navigation
• Instruments and accessories
• Aids to navigation
• Charts, navigation publications and Notices to Mariners

Watchkeeping and Regulation

The catalog includes basic principles of watchkeeping and the Navigation Safety Regulations (33 CFR 164). Read the regulatory text itself rather than relying on summaries, since the exam draws on what the regulation requires.

Compasses and Error Determination

• Principles of the magnetic compass
• Gyro compass error and correction
• Magnetic compass error and correction
• Determination of compass error by terrestrial observation

Environment

Meteorology and oceanography, plus tides and tidal currents, round out the module. Pilots work in water where set and drift matter, so do not treat tides and currents as an afterthought.

Domain 4: Navigation Problems: Chart Plot (Q372 or Q373)

The chart-plot module is where navigation theory turns into worked problems. The version you take depends on route: Q373 for river routes and Q372 for other routes. As with Rules, you take one, not both.

This is a working-skills domain. Candidates who read about running fixes but never plot one tend to struggle. Practice with real chart tools, check your answers against the geometry, and be able to reason about why a result is plausible. If you want a quick-reference companion for the formulas and procedures, see the NFCP Cheat Sheet 2026: One-Page Review of Must-Know Facts.

Domain 5: Local Knowledge (Q374)

Local Knowledge is the domain that makes this credential genuinely local. The published catalog states that its content is determined by the Coast Guard Sector for the local area and desired route. The guidance for candidates is to contact the Regional Examination Center (REC) for details.

In practice, treat this domain as a first-hand knowledge exercise. Time on the water, familiarity with your route, and written notes made while underway are far more valuable than any third-party outline. Ask the REC what is covered and how it is assessed, and build your preparation around that answer.

Domain 6: Chart Sketch (Q375)

The Chart Sketch module also falls under Coast Guard Sector determination for the local area and desired route, and the REC is the point of contact for details. The published guide describes what a chart sketch is expected to capture:

• Recommended courses
• Distances
• Prominent aids to navigation
• Channel and shoal depths
• Important route and bottom features

The guide also notes that parts of long routes may be accepted, so a very long route does not necessarily mean sketching every mile. Confirm with the REC exactly what portion applies to you before you invest in preparing sketches.

Complete Exam vs. Route Extension

One of the most important distinctions in the published guide is between the ordinary complete exam and the reduced pathways. The guide's table separates the standard candidate from those pursuing a route extension and from qualified Master or Mate over 1600 GRT cases.

This table is why your first conversation should be about your category. A candidate adding a route does not need to re-prepare Deck General or Navigation General, and spending weeks on them would waste effort. Conversely, an ordinary candidate should not assume the reduced pathway applies to them. Your individual approval to test controls which modules you actually sit. For eligibility and prerequisites, see NFCP Requirements 2026, and for testing logistics see NFCP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

Sequencing the Domains in Your Prep

Rather than a generic schedule, order your preparation around how the domains depend on each other and how long each takes to arrange. The structure below assumes the ordinary complete exam; trim it to Local Knowledge and Chart Sketch if you fall under a route-extension or qualified Master/Mate pathway.

The reasoning: Navigation General feeds directly into Chart Plot, so keeping them adjacent lets the theory stay fresh while you plot. Local Knowledge and Chart Sketch run in the background from the start because they depend on information you must obtain from the Coast Guard rather than study from a book. For a fuller plan, see the NFCP Study Guide 2026: How to Pass on Your First Attempt, and for a look at how the pieces fit together on test day, see NFCP Passing Score 2026: Exactly What You Need to Pass.

When you are ready to test your recall under realistic conditions, use the NFCP practice test to find the domains where your accuracy lags, then return to the relevant section above.

Putting the Domains to Work

Understanding the domain structure is only useful if it changes what you do. Three practical consequences follow from how this exam is built.

1. Do not budget by percentage. Official percentage weights are not published, so any breakdown claiming exact domain weights is invented. Prepare for all six groups and let your own practice results tell you where you are weakest.
2. Verify before you drill. The module catalog is the NMC's published topic list, but your approval to test and your route determine what you sit. Confirm with the REC rather than assuming.
3. Treat local material as a long-lead item. The two Sector-determined domains are the ones most likely to delay you if left to the end.
