M1GL Pass Rate 2026: What the Data Shows

Why a Published Pass Rate Is Hard to Find for This Credential

If you searched for the M1GL pass rate hoping for a clean percentage, here is the honest answer up front: for Master of 100 GRT-Limited, the public sources reviewed for this article do not publish one. There is no universal pass rate, no published pass mark, and no national count of how many candidates attempt and pass. That is not an oversight on your part as a researcher. It reflects how this particular credential path is structured.

Many credentials come with a single issuing body that administers one standardized exam, tracks results, and occasionally releases aggregate statistics. The Limited Master (Launch Tender) route works differently. The credential is governed by the United States Coast Guard National Maritime Center, but the examination requirement can be satisfied through an approved course, and the examination itself must be "appropriate to the authorized activity and route" under the federal regulations. That structure makes a single national pass rate close to meaningless, even if one existed.

What the data does show is more useful than a made-up percentage: the structure of the pathway, the boundaries of the approval, the five publicly listed preparation topics, and the specific places where candidates should verify requirements locally. For a broader look at difficulty, see our guide on how hard the M1GL exam is.

What M1GL Means Here: Limited Master (Launch Tender)

On this site, M1GL refers to Master of 100 GRT-Limited, approached through the Limited Master (Launch Tender) workflow. It is worth being precise, because the label is a workflow shorthand used here, not an official Coast Guard exam code. The course approval identifier that appears on the NMC register is NEWENG-254, and that identifier names a course approval, not an examination.

The credential is aimed at people who operate launch tenders: the small boats that shuttle people and supplies between shore and moored vessels for a yacht club, marina, or camp. The approved scope covers inland launch-tender operations between the employer's piers and moorings, within the approving Coast Guard Sector, and not more than one-half nautical mile from shore. The actual endorsement, the distance, and the Sector all depend on the individual application.

This is not a substitute for Limited OUPV, GLI08, an ordinary 100-ton Master credential, or a near-coastal syllabus. If you want the foundational definitions first, our explainers on what M1GL is and what M1GL stands for cover the naming in more detail.

What the Public Sources Do and Do Not Say

The evidence base for this article was reviewed on October 11, 2026. It included the course provider's public page and the current eCFR text directly, plus the official NMC NEWENG-254 register row retrieved as indexed agency-PDF text. The direct PDF returned a 403 error, so that row came through indexed text rather than the original file. No paid curriculum and no unpublished OCMI examination specification were accessed.

From those sources, here is what is and is not established:

• Established: The NMC register identifies Limited Master (NEWENG-254) as satisfying the examination requirement under 46 CFR 11.456(a)(3), within its approval limits.
• Established: The five public preparation topics are Rules of the Road, aids to navigation, safe boating subjects, state regulations, and federal regulations.
• Established: The course must be completed within one year of application, and the certificate may support one application resulting in an endorsement.
• Not published: A pass rate, a pass mark, a question count, an exam timer, domain weights or percentages, and a current examination version.
• Not published: Detailed course objectives, a revision date for the topic list, or an exhaustive statement of examination scope.

If you are looking for the scoring side of the picture, our page on the M1GL passing score addresses the same absence of a published threshold.

The Five Preparation Topics and Where Candidates Struggle

Because no pass rate exists to tell you which areas trip people up, the practical question becomes: what does each of the five topics require, and where is mastery hardest to fake? The list below reflects the topics the course provider publicly lists. It is a preparation outline, not an issuer-authored blueprint, and it carries no published percentages.

For a deeper walkthrough of these areas, see our complete guide to all five M1GL content areas.

Why Your Route and Sector Shape the Exam You Face

Under 46 CFR 11.456(a)(3) and 11.429(a)(3), the examination must be appropriate to the authorized activity and route, and the applicant's OCMI approval controls. That single sentence explains why a clean pass-rate statistic is unlikely to exist. Two candidates pursuing the same label can face different local expectations depending on their Sector, their route, and their employer's operation.

The documented preparation context is narrow: inland launch-tender work between the employer's piers and moorings, within the approving Sector, within one-half nautical mile of shore. Technical practice based on the five topics should stay within that context. Treating the course topic list as universal exam coverage, or applying it to a different route or activity, goes beyond what the sources support.

Eligibility questions that sit upstream of the exam are covered in our M1GL requirements guide.

Course Completion Is Not the Endorsement

One of the most common misunderstandings around this pathway is conflating the course certificate with the credential itself. They are different things. A course completion certificate is not the Coast Guard-issued endorsement. The certificate documents that you completed an approved course; the endorsement is issued by the Coast Guard through the application process.

Two practical constraints from the NMC register matter for timing:

1. The course must be completed within one year of your application.
2. The certificate may support one application resulting in an endorsement, so it is not a reusable credential.

The provider lists current classes in October through December 2026, which is relevant if you are planning around a specific application window. For scheduling mechanics, see our notes on M1GL exam dates and scheduling, and for budgeting, the M1GL certification cost breakdown.

Sequencing Your Preparation Around the Five Topics

With no weights published, you cannot prioritize by percentage. A reasonable approach is to sequence by dependency and by how local the knowledge is. The plan below is one way to order the five topics; adjust it to your own timeline and class date.

The reason to leave state regulations for the end is that they depend most on your specific location, so you will benefit from confirming local details after the foundational material is solid. For a fuller plan, our M1GL study guide goes further, and the M1GL cheat sheet offers a condensed review.

How to Evaluate Pass-Rate Claims You See Online

Because the underlying data is not public, you will encounter confident-sounding numbers elsewhere. Here is a quick way to sort credible statements from noise.

• Look for a named source. A genuine statistic points to the body that collected it. If the claim cites no source, treat it as unverified.
• Check which credential it describes. The M1GL acronym is shared by several unrelated credentials. A figure for a different M1GL says nothing about Master of 100 GRT-Limited (Launch Tender).
• Distinguish course completion from exam results. A provider saying most students finish a class is not the same as an examination pass rate.
• Be wary of precision without a method. A figure quoted to a decimal point with no description of how it was gathered is a warning sign.

If you are weighing whether the credential makes sense for you at all, our analysis of whether the M1GL certification is worth it and the discussion of M1GL jobs frame the career side, and you can sharpen your readiness with questions on the main practice test site.

Frequently Asked Questions

The takeaway on pass rates is straightforward: the credential's structure, built around an approved course and local OCMI determination, means no single national figure exists to quote. Focus your energy on mastering the five topics, confirming your local requirements, and using the practice test site to check your readiness.
