There is a specific Exam Approval Request form that candidates need to fill out and send to the Board Office. Once submitted the proof of 3 years experience the board will send PSI confirmation to approve the SS# for testing. The process will take less than 3 business days if faxed to (615) 532-2868. ALL PLUMBERS MUST BE PRE-APPROVED TO TEST AND WILL BE REQUIRED TO LIST THREE (3) YEARS OF PROVEN EXPERIENCE.
