Scheduling the exam

Visit PSI’s Website to schedule your exam, and to find scheduling information, or call PSI at 800 733.9267. If registering over the phone, you will need to advise them you are (1) taking National Ground Water Association's exams, (2) taking the exams for your state license, and (3) which exams you desire to take. 

After your exam

PSI will provide you with your score report upon completion of the exam. You must submit a copy of your score to the licensing body to which you are applying. NGWA does not relay exam scores to individual state agencies. 

If you need another copy of your score report, NGWA can reprint them for a fee. Contact the certification coordinator at certification@ngwa.org​ or by phone at 800 551.7379, or 614 898.7791 if you are outside the United States, for more information. 

Contact the state licensing body for information about applications, requirements, and retesting procedures.
