In order to register for either the NRPP measurement or mitigation exam, you will need to go to the PSI website, www.psiexams.com, where you will register online and choose your testing date and the location of your choice. You will also need your approved NRPP Course ID number which can be found on your Course Completion Certificate given to you by the training provider of the entry level course you attended. If you do not see a NRPP Course ID number please contact your training provider to obtain this code before you begin your registration process for the exam. The cost for the NRPP Measurement Exam is $100.00 and the cost for the NRPP Mitigation exam is $110.00. All major credit cards are accepted.

You MUST complete an application and submit required fees and documents directly to the NRPP Administrative office in order to become certified through the National Radon Proficiency Program.
