Whenever possible and where appropriate, course requirements should include components that utilize modern computer and instrumentation labs and facilities. Please keep in mind that some schools may require pre-requisite courses prior to enrolling in the above coursework.

Applicants must pass a “closed book”, qualifying examination to demonstrate knowledge of general meteorology (applicants who have already earned the Certified Broadcast Meteorologist (CBM) designation are exempt from taking the exam). A test of 100 multiple choice and true/false questions will be administered at a test center or remotely by SMT/Promteric through an online proctored environment. Applicants must have a grade of 75 or higher in order to pass the written exam. You will receive information on how to register for the exam once you apply. Please note that you will be unable to register for the exam through SMT/Prometric until you submit a CDM application and receive an acknowledgment letter from AMS. If you would like to retake the test, please contact AMS Headquarters before you re-register at Prometric.

SMT/Prometric User Guide

After successfully passing the multiple choice exam, applicants will receive instructions on submitting work samples for review by the AMS Board of Digital Meteorologists.

Candidates must submit work samples from at least 2 of the 3 below categories, for a total of 6 points. Up to 10 points of work samples are permitted in case you are unsure if one of your samples is satisfactory. All work samples must be time stamped within 2 months before and after receipt of your instructions letter. For example, if you received your letter in July, samples must have been produced between May and September. The categories are as follows:

Category 1) Text discussion, video discussion: 4 points

Text discussion: Are forecast based, with the applicant’s own forecast and reasoning behind it in a clear manner. There must be depth to the content submitted. An active and routine forecast must be submitted.

Video discussion: Live streams or recorded videos are both accepted forms of content, ranging from 1 to 15 minutes. The reviewers will account for the lack of premium weather graphics (IBM, AccuWeather, Baron) technology. One active and one routine forecast must be submitted. Graphics must be legally available for their commercial use.

Category 2)  Hard journalism stories, data or explainer story, weather graphics: 2 points

Journalism Story: These stories will use sourcing, a strong theme and high focus to talk about a community. Content can be submitted via audio, video, or writing. Examples include impacts of coastal flooding on a community, rebuilding in the aftermath of a tornado or showing how great weather for tourist season helped the economy.

Data or Explainer Story: These stories will typically use research, analytical skills, and a strong focus to explain a certain weather event of phenomena. Content can be submitted via audio, video, or writing. Direct sourcing from experts in the field may be used as well. Examples include a recap of a major storm, teaching atmospheric optics or using climatology to show how climate change has impacted a region.

Weather Graphics: A standalone graphic, a sequence of slides or animated graphics can be used to attain these points. It is OK if these graphics were used on broadcast television, video discussions or text discussions. However, this graphic must not be used in any other submission. Content from professional weather data systems (IBM MAX, AccuWeather, Baron, etc.) or from designer applications (Adobe Premiere, Adobe Photoshop, PowerPoint, etc.) are accepted.

Category 3) Social media posts: 1 point

Three social media posts must be submitted to earn the point, each concerning a different weather event. Posts can, but do not have to, be from a mix of social media platforms, or from the same. A Tweet thread will count as one post. Social media videos that are clearly different from other forms of traditional video content are acceptable. For example, Instagram Reels and TikToks are allowed, as well as other native vertical video content that is uploaded into a social media platform. Applicants must indicate if the social media post is a text forecast discussion, a video forecast discussion, data or explainer story. Links to a video or story are allowed but will only be reviewed to make sure that it is relevant to the story. It will not be graded. The board will review the applicant’s social media portfolio to ensure professional conduct. Not every post will be looked at but an arbitrary amount of content will be reviewed by the graders.

Samples may be submitted in Spanish and will be evaluated by the AMS standing Board of Spanish-language evaluators. Please indicate on your application if you would like to submit Spanish-language samples.
