CBM Requirements 2026: Eligibility, Prerequisites & How to Qualify

What the Certified Broadcast Meteorologist Credential Actually Asks Of You

The Certified Broadcast Meteorologist credential, issued by the American Meteorological Society (AMS), is built for people who forecast and communicate weather on air. That shapes everything about its requirements. Unlike a credential that you can earn by passing a single test after a short course, the CBM asks you to document your education, document your professional broadcast history, pass a written examination, and demonstrate your on-air craft in recorded weathercasts.

If you are still orienting yourself, our explainers on what CBM certification is and what CBM stands for cover the basics. This article focuses on one question: can you qualify, and what exactly do you have to show?

The requirements fall into four buckets:

• Education: an accredited degree plus specific coursework, backed by transcripts.
• Experience: a minimum amount of professional on-air time.
• Examination: a closed-book written test of 100 questions.
• Demonstrated performance: two additional weathercasts judged against defined criteria.

The Education Requirement: Degree, Coursework and Transcripts

The educational prerequisite is an accredited meteorology or atmospheric-science degree, or an approved equivalent. Two parts of that sentence deserve attention.

"Accredited" and "approved equivalent"

The degree must come from a recognized program in meteorology or atmospheric science. If your degree is in a different field, the pathway is the "approved equivalent" route, which means your academic record is evaluated against what the program requires rather than assumed to qualify. Candidates with a communications or journalism degree who later completed meteorology coursework, for example, should expect their situation to be reviewed on the merits of their transcripts rather than on the title of their diploma.

Required coursework and transcripts

Beyond the degree itself, the program calls for required coursework and the transcripts that prove it. In practical terms, assemble your official transcripts early. Transcript requests from registrars can take days or weeks, and it is a needless way to delay an otherwise ready application.

On-Air Experience: Counting Your Years Correctly

The experience requirement is where many otherwise strong candidates miscount. The standard is:

• 2 years of full-time on-air experience, or
• 3 years of part-time on-air experience.

The qualifying work is on-air weather presentation in a professional setting. Student-station work is excluded. Time at a campus television or radio outlet, however valuable for your development, does not count toward the clock. If you graduated and moved straight into a professional market, your clock starts with that first professional on-air job, not with your sophomore-year student newscast.

Full-time versus part-time

The part-time path asks for an extra year, which reflects the lower volume of on-air hours. If your work has been a mix of weekend shifts and fill-in work, be ready to describe your schedule accurately. Overstating hours is a quick way to create problems at the review stage.

What is not required

Some credentials add a formal training-hour or reference-letter requirement. For the Certified Broadcast Meteorologist program, no separate training-hour or reference requirement has been verified in the public program materials we reviewed. That said, program procedures can change, so confirm the current application checklist with AMS when you apply.

Application and Fee Mechanics

The sequence matters: you apply through AMS first, and only then schedule your exam. Do not try to book a testing slot before your application is in.

The written exam is delivered through a testing provider (currently SMT/Prometric, although older AMS FAQ material still names PSI), and you can test remotely or at a testing center. Calculator and adaptive-testing rules are not verified in the public materials, so check your appointment confirmation rather than assuming.

Those first-attempt totals exclude AMS dues and your preparation materials. Note the structure: the testing fee is charged each time you schedule, so a retake means paying the scheduling fee again. For a deeper walk through the budget, see our CBM certification cost breakdown, and for timing logistics see CBM exam dates, testing windows and scheduling.

The Two-Part Process: Written Exam Plus Weathercast Evaluation

This is the single biggest feature that separates the Certified Broadcast Meteorologist credential from knowledge-only certifications. Qualifying is not complete when you pass the written test. You must also submit on-air work.

The weathercast submission

The program requires two additional weathercasts. The requirements for them are specific:

• They should be active and routine, meaning representative of your normal on-air work rather than a specially staged showpiece.
• Each runs a maximum of 5 minutes.
• You must earn an average above 3.0 separately in each of three criteria: Graphical Content, Explanation, and Presentation. A strong score in one category does not offset a weak one in another.
• If your submissions are in Spanish, an English transcript is required.

It is worth being careful with one data point you may see circulating. A 2019 Board note estimated that about half of candidates passed their first weathercast evaluation. That is a historical estimate about the weathercast step, not a current statistic and not a written-exam pass rate. Current written-exam pass rates are not publicly disclosed; our CBM pass rate analysis explains what can and cannot be said from the available data.

What the Written Exam Covers

The written component is 100 multiple-choice and true/false questions, closed book, with a 75% passing score. How many of the 100 are scored versus unscored has not been disclosed. A legacy-provider official FAQ lists 120 minutes; reconfirm the time limit against your current appointment details. For more on the cut score, see CBM passing score explained.

Preparation follows the fifteen subject headings on the AMS written-test reference list. Those headings are unweighted: AMS does not publish topic percentages on these pages, so any claim about which domain carries the most questions is guesswork. The AMS Glossary of Meteorology entry that precedes the list is a general terminology resource, not a sixteenth subject.

For a topic-by-topic walk-through, read our complete guide to the 15 CBM content areas. Several of these headings map directly onto daily broadcast work, which is why experienced on-air meteorologists often find the exam more approachable than a candidate coming only from an academic background. Others are more technical than most newsroom routines require.

How hard this all feels depends on your background; see how hard the CBM exam is for a candid look.

Keeping the Credential After You Earn It

Qualifying is not a one-time event. The credential is valid for 1 year and is renewed annually. The renewal fee is $206 for members and $515 for nonmembers. In addition, 28 professional-development points must be earned every 5 years.

Factor that into your decision before you start. The ongoing cost and the continuing-education expectation are part of the real price of holding the credential, and they interact with questions like whether the certification is worth it. If compensation is part of your thinking, our CBM salary guide and CBM jobs overview look at where the credential fits in the broadcast market.

A Qualification Roadmap Sequenced Around the Domains

You do not need a generic study calendar so much as a sequence that respects the two-track structure of this credential. The plan below assumes you have already confirmed your degree and experience eligibility. It is one possible ordering, not an official schedule.
