Massachusetts Wastewater Operator Certification Exams

NEIWPCC is responsible for the Massachusetts wastewater operator certification examinations. Beginning in July 2009, NEIWPCC, working with ABC and the Massachusetts Board of Certification, began offering computer-based versions of the certification exams through AMP (now PSI).

Certification examinations for Massachusetts Operators are now ONLY offered at PSI/AMP testing locations. As of January 2018, there are now eight locations in Massachusetts as well as testing centers in RI, NH, and NY.  (Note that the in-person appeal process and exam review is no longer available.)

Please Note:  As the COVID-19 outbreak continues to spread, in order to continue to help protect the health and safety of candidates, clients, and employees, PSI/AMP has made the difficult decision to temporarily close their test centers starting March 19th. 

If you previously scheduled an exam with them, please reschedule your exam online (at no cost through April 30th).  If you need to contact them with questions, please call 833-256-1420, you may experience longer than usual wait times under the current circumstances.

Note from ABC and PSI/AMP:


We know COVID-19 is effecting everyone, including our business partners, member, and clients. ABC is committed to keeping you informed about important industry updates.

Current Plan for PSI Test Centers
The Center for Disease Control extended the federal social distancing requirements through April 30, 2020. These recent events have impacted PSI’s ability to serve candidates in test centers.

  • PSI owned and operated test centers in the United States will remain closed through April 30, 2020
  • Sites will re-open meeting social distancing requirement on Friday, May 1, 2020
  •  A complete list of site closures can be found here

While many third-party test partners practice closures as required by state and local mandates, there are locations open in the United States and globally as closures are dependant on regional mandates.

Protective Equipment Policy
PSI has adjusted policy on the use of facemasks and gloves based on recommendations of the CDC.

  • Candidates will be required to provide their own facemasks and gloves
  • Facemasks will be removed during check-in process to verify identity and take photo
  • Candidates are responsible for disposing of used facemasks and gloves securely outside of the test center

Proud to Partner with You
As we navigate this changing environment, please know we are here to support you! Both PSI and ABC will be working closely with our members and clients to ensure affected candidates are addressed appropriately.

Please reach out to Tom Healy at if you have any questions or if you’d like to discuss impact to your program in more depth.

To Obtain a Wastewater License

Once you have obtained a PASSING grade on the computer-based exam, you must download the computer-based exam license application form and submit it to NEIWPCC with (a copy of) your PASSING exam results and license fee. NEIWPCC will then issue your new Wastewater Operator license.

There is no need to contact NEIWPCC for non-passing exam results. You may schedule and re-take another computer-based exam at any time.
