How do I become certified?

You must meet the requirements set forth in the certification rule (327 IAC 5-22): (1) complete an application to sit for the certification exam, (2) pay a $30 application fee, and (3) pass the exam with a score of 70% or higher. A copy of the certification statute [PDF] and the certification rule [PDF] is available on this web site. The minimum requirements to sit for an exam are: one year of hands-on experience in the operation of wastewater treatment plants and a GED or high school diploma. There is no substitution of education for the one year of experience.
