New exam 200 x 143


Certification Exams are available in two formats.  For most of the U.S. (if a facility is close to you), the exams are available through a computer-based testing facility - PSI Testing Centers.  For areas in the U.S. that are not close to a PSI facility, exams are available directly through NRPP with the services of a Proctor.




Computer-Based Testing Procedure - PSI:

These exams are provided through PSI Lasergrade, which is a computer based testing facility.  You will need to find the facility closest to you, then schedule the exam directly through PSI.
