The first step in earning the CPH credential is to determine your eligibility criteria. The next step includes applying for the exam, followed by an application review, and notice of approval to sit for the CPH exam. The third step is to schedule the CPH exam, allowing plenty of time for self-study preparation, using the NBPHE sponsored study materials. The next step is to sit for and successfully pass the CPH exam. The CPH credential will be awarded to the public health professional that successfully passes the CPH exam.

How long do I have to take the CPH exam?

  1. Wheelchair access is available at all established Assessment Centers. Candidates must advise Meazure Learning at the time of registration that wheelchair access is necessary.

See our CPH candidate handbook for more details about the scheduling and examination process.

Are there study materials available?

NBPHE provides sample questions and two practice exams.  Several partner organizations offer study guides and review materials. See study resources.

Can I retake the CPH exam?

The day after you have taken your exam (or if you were absent on your scheduled exam date) you may reapply online via CPH Central. The retake fee is $150. Once paid, you will receive an email from Meazure Learning with scheduling instructions.

My score report says that I’m “Provisionally Certified.” What does that mean?

Candidates who take the exam under the student eligibility criteria are not fully certified until they have completed their degree. The CPH status for these student candidates is pending until after your academic institution verifies with NBPHE that you have completed all requirements for graduation. This will happen electronically between your academic institution and NBPHE. Then you will automatically receive a certificate recognizing your accomplishment and your CPH status will be active.

Will anyone else see my score?

Student and alumni scores are only shared with the academic institution which conferred or will confer candidates’ degree. All Certified in Public Health examinees in good standing are listed on the NBPHE website.

What is the passing score needed to pass the exam?

Because the CPH exam is updated every year and the cut score needed to pass the exam changes with each new exam form, a standard passing score is not published.  However, passing rates are available.  Between 2018 and 2022, over 85% of candidates pass the exam.  (Please note: The score needed to pass was NOT 85%.)

Computer-based testing centers

Meazure Learning testing centers where you can take the exam are located throughout the US and in over 100 other countries. CPH examinations can be scheduled Monday-Friday in the morning and afternoon and at some test centers on the weekends.
