The Mark of an Energy Professional
Since its inception in 1981, the Certified Energy Manager (CEM) credential has become widely accepted and used as a measure of professional accomplishment within the energy management field.  It has gained industry-wide use as the standard for qualifying energy professionals both in the United States and abroad. It is recognized by the U.S. Department of Energy, the Office of Federal Energy Management Programs (FEMP), and the U.S. Agency for International Development, as well as by numerous state energy offices, major utilities, corporations and energy service companies.

When you've earned the right to put the initials "CEM" behind your name, you've distinguished yourself among energy management professionals. Simply put, the designation CEM, which stands for Certified Energy Manager®, recognizes individuals who have demonstrated high levels of experience, competence, proficiency, and ethical fitness in the energy management profession. By attaining the status of CEM, you will be joining an elite group of 14,000 professionals serving industry, business and government throughout the U.S. and in 25 countries abroad. These high-achieving individuals comprise a "Who's Who" in the energy management field.  The designation "Certified Energy Manager" is a registered trademark with the United States Patent and Trademark Office.

*If you don't yet meet the education or experience eligibility requirements for the CEM, you may be interested in pursuing our Energy Manager in Training (EMITTM) certification. This is an excellent pathway towards obtaining your CEM designation.

Examination and Training Requirement
All CEM candidates must attend one of AEE's preparatory CEM training seminars, and complete and pass in a four-hour time frame a written open-book exam which is proctored by an approved exam administrator. (Information on seminar training options is provided below.)

All CEM candidates taking the exam in the United States (only) will take the revised format CEM Certification Exam. The new format exam contains the same number of questions as previous versions, 130, and the exam duration will remain 4 hours. The new exam will not include optional sections, as in the past; rather, the exam will include questions from all 17 sections of the CEM Body of Knowledge. This differs from the international version of the CEM exam, which will still contain optional sections. You must bring a hand calculator to the exam since the CEM test does not allow computers, tablets or cell phones to be used for calculations on the test.

An intensive jobs task analysis was performed for the CEM and a weighted percentage of topics was developed for the CEM Body of Knowledge. Although a specific number of exam questions for each topic will not be provided, as it may change, the number of questions on the exam will align with the content percentages listed in the following CEM Body of Knowledge.
