Process to Earn Your Certification

1: Assess your knowledge and experience
The Technical Body of Knowledge is an outline of topics covered on the certification exam. The Technical Competency Model describes the knowledge, skills, and abilities required by manufacturing professionals. It will help you better envision your role and evaluate your readiness for certification.

2. Recommended Reading Material
Exam questions are based on specific recommended reading materials selected by knowledgeable and experienced individuals. (Please note that the exam is open book)

3. Optional Additional Preparation

  • Engineer Self-Assessment: This online self-assessment evaluates your knowledge and determines your strengths and weaknesses before you take the exam.

  • Technologist Online Review Program: Although designed for the Technologist exam, this review program is extremely beneficial for those preparing to take the Engineer exam. Note that calculus, Taguchi, time value of money, and depreciation are not covered as they relate to the CMfgE exam.

  • Classroom Review Program: This collaborative, instructor-led review program helps solidify your understanding of the body of knowledge and key manufacturing concepts. It is a valuable opportunity to provide you with a foundation for completing the CMfgE.

4. Apply for the Exam, Schedule and Take the Exam

The Certified Manufacturing Engineer exam is offered in online and paper/pencil formats. You have one year to take the exam from the date you apply.

The Certified Manufacturing Engineer exam is a four-hour, open book and open notes exam. It consists of approximately 180 multiple-choice questions mapped to the Body of Knowledge. Exam questions are taken from the recommended reading materials.

To pass the exam, you need to score 60% or higher. After your exam is scored, you will receive official results by mail, which includes an Examination Analysis Report that provides a breakdown of your results by knowledge area. Upon passing the exam you will earn your Certified Manufacturing Engineer (CMfgE).

If you did not pass the exam, you can apply to retake the exam 30 days after you receive your exam results. Use the Examination Analysis Report to focus on weaker knowledge areas to help prepare you for retaking the exam. A reduced exam fee is offered for retaking the exam.

You must submit your Proctor Form and Agreement to SME at least two weeks before your scheduled exam date.

5. Recertification
Keeping the credentials you worked hard for is just as important as earning them. To ensure you stay on top of the latest advances, and maintain a strong competitive edge, you must recertify every three years to maintain your Certified Manufacturing Engineer (CMfgE).

“Certification has helped me become more aware of expectations relating to my profession, and has required me to stay involved and active. Through a relatively short time my certifications have brought me a “step up” from peers who are not involved in learning new technologies.”
