The licensure examination for Master Plumbers can be taken by both non-degree and degree holders. We started our review program for Master Plumbers in 1989. This made us, MRII, as the pioneer review center offering Master Plumbing Review.
Up to date, MRII is still offering the review program and producing topnotchers in Master Plumber Licensure Examination.
The Master Plumber Licensure Examination is usually held in February and July by the Professional Regulation Commission (PRC).
