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.


FAQs about the exam process are below. If you have any remaining questions, see our candidate handbook or email info@nbphe.org.

How do I register for the exam?

How do I schedule my exam once my eligibility has been verified?
Once your eligibility has been verified, you will receive an email with instructions for how to schedule your exam. If you do not receive an email but your status is “Eligible”, please contact us.

When is the CPH exam held?
The CPH exam is offered all year round. As long as a proctor and/or the computer-based testing facility of your choice is available, you will be able to schedule your exam any time.

What about candidates with disabilities / requesting a special accommodation?

NBPHE is committed to ensuring that no individual with a disability is deprived of the opportunity to take the examination solely by reason of that disability. AMP testing facilities will provide reasonable accommodations for candidates with disabilities.

  1. Wheelchair access is available at all established Assessment Centers. Candidates must advise AMP at the time of registration that wheelchair access is necessary.
  2. Candidates with visual, sensory or physical disabilities that would prevent them from taking the examination under standard conditions or candidates who request special accommodations under the Americans with Disabilities Act must fill out the two forms for ADA accommodations within the CPH Candidate Handbook. E-mail the two forms 45 days prior to your desired testing date to e-mail amp-info@goamp.com with cc: info@nbphe.org
How do I update my email or mailing address?

Your email address is your username in CPH Central. To change it, please submit the request here. To update your name or other contact information, log in to CPH Central and click your name in the upper right corner, then select ‘Profile’.

Can I reschedule my exam?

You may reschedule your appointment once with no additional charge online at www.goAMP.com or by calling PSI at 888-519-9901 at least two business days prior to your scheduled appointment. If you reschedule within two business days of your scheduled appointment, you will be considered absent from the exam and may schedule another exam date after your scheduled date has passed.

What are the exam fees?

Standard registration – $385. For a list of available discounts see: https://www.nbphe.org/cph-fees-discounts/

Can members of the U.S. Armed Forces use Military Tuition Assistance benefits for the CPH exam fee?

Yes, active duty members of the US Armed Services may be able to use benefits of the Military Tuition Assistance Program to pay for the CPH examination fee.  More information can be found at: http://www.militaryonesource.mil/voluntary-education?content_id=268274 or call 800-342-9647.

Is the registration fee refundable?

The registration fee is not refundable for candidates applying under the student and alumni criteria.   Applicants applying under the work experience criteria will be refunded the application fee if they are not approved. Once approved, the fee is not refundable.

Can I use veterans' benefits for the CPH exam?

Yes. As of November 2009, NBPHE is approved to offer the CPH exam through the U.S. Department of Veterans Affairs. Veterans, their eligible dependents, and reservists may qualify for reimbursement of the CPH exam costs through their veteran’s education benefits. For more information, please contact the Veterans Benefits Administration office in your area or visit the U.S. Department of Veterans Affairs Education Benefits website at: http://www.gibill.va.gov.

Exam Information

The exam consists of 200 questions and you have 4 hours to complete it. All questions on the exam are multiple choice and single-best answer.  For an overview of the exam topics, see the Content Outline.

What can I expect during the exam?

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

Are there study materials available?

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

Can I retake the CPH exam?

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 PSI 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 2012 and 2020, over 75% of candidates pass the exam.  (Please note: The score needed to pass was NOT 75%)

Computer-based testing centers

PSI 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 Saturdays. Search for a testing center here.  If you are testing in the US, select USA and then sort by state.

See this video for more information about testing at a computer-based testing center:  PSI Test Center Experience.

Remote proctoring

All candidates are able to test via remote-proctoring. Remote-proctoring allows candidates to take the exam from their own computer.  Remote-proctoring is available 24 hours a day every day except for December 25 and January 1.

You must confirm the following technical and physicals requirements before sitting for your exam

Technical requirements

  • Desktop or laptop computer (tablets and smart phones are not supported). You may connect a laptop to a monitor
    • 2GB RAM Memory; 1 GB Free Disk Space, minimum 1368×768 screen resolution
    • It is critical you pass the PSI compatibility test prior to scheduling your exam using the computer and internet connection with which you will take the CPH exam. If you cannot connect during your test administration, you will be considered absent. Please note, if you are using a VPN, you must disable it. Check your set-up now.
  • Stable Internet access
    • Minimum 400 kb/s download and upload
  • Browser: Current version of Google Chrome.
    • The browser must accept third-party cookies for the duration of the exam ONLY
  • Web camera (built-in computer cameras are accepted)
    • Minimum VGA 640 x 480 resolution, enabled built-in or external microphone
    • Ensure you can easily move the computer/camera around, as you will need to show your surroundings.
  • Microphone
  • TIP: As some computers may have automatic updates enabled, it’s always a good idea to check your computer upon registration and then again right before the exam. For example, some Windows updates have restricted certain Ports, prohibiting you from passing PSI’s compatibility test and therefore making you unable to connect to PSI on exam day.

Physical requirements

  • Valid government-issued photo ID.
    • Note: Military or DOD ID is not accepted for online proctoring because the exam is recorded and video is retained for up to 90 days, and we cannot, by law, retain copies.
