About Certification

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

Program Overview

The PSAI's certification program for portable sanitation professionals dates to 1992 when the Association developed a set of best practices for the industry, a training course to teach them, and an exam to measure understanding of the concepts.

Since the program's inception, more than 2,000 individuals have successfully passed the certification exam. The exam consists of 50 questions relating to skills and general knowledge of domains required for competency as a portable sanitation professional. Certification is current for three years before it has to be renewed.

To assist candidates for certification in preparing for the exam, the PSAI today offers a Basic Service Technician training series designed to teach the basic competencies required for success in the role of a portable sanitation professional.

How to Become Certified

Certification is voluntary. While all credential seekers are welcome to attend the Basic Service Technician training series for a review of best practices, these  courses are not a PSAI prerequisite prior to sitting for the exam. In some states, however, both the Basic Service Technician training course AND the exam are required by for licensure. Be sure to check with your state’s licensing body for details. To be eligible for certification an applicant must:

  1. Complete the exam application and pay the appropriate fees
  2. Provide information relating to waste disposal practices
  3. Provide two professional references
  4. Successfully pass the examination
  5. Agree to adhere to the CPSP Code of Ethics


The Future of the Program

In 2019 the PSAI will be introducing the first significant update to the Certification Program. This will include an updated exam, clarified eligibility criteria, and new continuing education requirements for maintaining certification. The goal of these updates is to ensure the program remains relevant, up-to-date, and approved by several states for their licensing programs. Any professional that is certified prior to March 2019 will be grandfathered into the program and will need to meet the CE requirements after their next renewal.
