2. Test at a PHTA national, regional or chapter-sponsored education and testing event. Find a listing of upcoming events here. 

3. Test at a community college or university near you. Proctored exams must be taken at an accredited college or university. If you opt to take the exam at a college or university test center, or chapter event, there may be an additional exam proctor fee that you will pay directly to the proctor at the time of the exam. These fees can vary but typically are from $0 to $40.


If testing at a college or university, participants are responsible for the following: 

  • Scheduling an appointment for testing at a local community college or university testing center. 

  • Submitting this form at least two weeks prior to your exam date to ensure test materials arrive on time. 

  • Providing PHTA University with your name, full mailing address and exam date. 


Please note that PHTA does not maintain a list of testing centers throughout the U.S. We rely on local community colleges and libraries that offer their proctoring services to the general public.
