You will have three hours (180 minutes) to complete the exam. There are 140 scored items on the exam. The exam also includes 20 unscored items that are being pretested for use on future exams.

The exam is NOT considered complete when you achieve a certain number of correct answers. Any unanswered questions will be scored as incorrect.

Examples of valid primary forms of identification are: driver’s license with photograph; state identification card with photograph; passport; military identification card with photograph. No expired or temporary IDs allowed.

If your name on your exam registration is different than it appears on your identification, you must bring proof of your name change (e.g., marriage license, divorce decree, or court order).

Q:  What will it be like at the Test Center?

A:  Test Centers may have multiple testing workstations in one room; all tests are proctored and recorded. There may be other examinees in the room taking different tests.

Because each computer-based test is independently timed, you do not need to wait for others to arrive and/or start the test. A clock on your computer will count down until all 180 minutes have been exhausted. Your photo will be taken when you begin the exam and will remain on your computer screen until you complete the exam. The proctor will ensure that you remain in compliance with CBDM policy as you complete the exam.

Q:  When will I find out if I have passed?

A:  You will receive your score report from the test center proctor after you finish taking your exam. It will indicate your score as well as if you passed the exam. ANFP will be notified of your official test results within about seven to ten business days.

Q: Can I get a copy of my exam or the questions that I missed?

A: For security purposes, we cannot release copies of the examination, in part or whole, including or the questions that were missed. Examinees who do not earn the minimum standard for passing the exam receive a report that shows the number of questions answered correctly in each of the five content areas. This enables examinees to determine the areas where they are strong and the areas where they may require additional study. In preparing to retake the CDM Credentialing Exam, examinees should focus attention particularly on the content areas where they scored lowest.

Q:  When do I get my certificate?

A:  Individuals who are an ANFP member when they pass the exam and maintain their Professional membership with ANFP through the following May 31 will automatically be upgraded to Certified status, with the initial certification fee waived one time. CBDM will send information about the certification.

Individuals who pass the exam and are not an ANFP member must activate their certification within one year of passing the exam. They will receive an email from ANFP explaining the activation fees as well as information about the benefits of membership. They may choose to activate their credential as a member or non-member. After activation is completed, CBDM will send information about the certification.

Failure to activate certification within one year of passing the exam will result in your certification being terminated. To be eligible for certification again, you must meet the current eligibility requirements, submit an exam application with fees for review and approval, and receive a passing score on the exam.

After activation of the certification, the CDM, CFPP credential may be used as long as certification is active, valid, and in good standing. Certificants must comply with all recertification requirements to maintain use of the credential. Failure to do so will result in the certification being terminated. 

Q: Do I have to pay again to retake the exam?

A: Yes, you have to complete and submit a new application with fees for review and approval and fully meet the current eligibility requirements each time you want to sit for the exam. You must wait 90 days between retakes of the exam. If eligible, there is no limit to how many times the exam may be retaken. The 90-day wait period must be met for any retake of the exam.

Q:  How is the passing score determined?

A: Historically, answering about 70% is of the scored items has been required to pass the exam. Your score report will indicate the exact number of test items that you must answer correctly to pass the exam as well as the number of test items that you answered correctly out of the possible 140 scored items. (The 20 pretest questions are not scored and are not included in the total score.) Your report will also indicate if you passed or failed the exam. Individuals who do not pass the exam will also receive a breakdown of their score by the exam content area.

The passing score is determined by a cut-score study called a modified Angoff procedure. This statistical study relies on subject matter experts – in our case, CDM, CFPPs and Registered Dietitian Nutritionists (RDNs), to estimate the difficulty of each question for a ‘minimally competent practitioner,’ or dietary manager that is considered entry level. The data is then used to determine the score required to pass the exam.

On average, about 75% of candidates pass the exam on their first attempt. The pass rate statistics are published below on a semi-annual basis.

Q:  What are the exam statistics?

A: Pass/fall statistics will be reported twice per year.
