About Certification

The PSAI’s certification program for Portable Sanitation Professionals sets the standard for skills and knowledge in our industry.

Program Overview

The PSAI’s certification program for portable sanitation professionals is the only credential in the world designed to recognize the specific competencies required for success in front-line roles in our industry. Since the program's inception in 1992, more than 2,000 individuals have successfully become certified.

The program consists of two parts: the Basic Service Technician Training series, which prepares candidates for certification by teaching basic competencies for portable sanitation operations, and a 50-60 question examination. The Basic Service Technician training series is not required by the PSAI for certification, though some states (such as Illinois and Georgia) do require the training series in additiona to the exam for licensure. Be sure to check with your state’s licensing body for details.

Certification is current for three (3) years before it must be renewed.

Levels of Certification

There are two levels of certification based on how many hours of job experience a candidate has. A Certified Portable Sanitation Professional (CPSP) has at least 2,000 hours of front-line experience, while a Certified Portable Sanitation Apprentice (CPSA) has been on the job for less than 2,000 hours. That’s one year of experience working full-time in a role such as service technician, driver, pick-up and delivery worker, or similar jobs.
