Certification examinations for Massachusetts Operators are now ONLY offered at PSI/AMP testing locations. Presently, there are three locations in Massachusetts as well as testing centers in RI, NH, and NY. The in-person appeal process and exam review is no longer available.
Download information here to schedule a computer-based exam directly with PSI/AMP. You no longer need to contact NEIWPCC in order to take an exam. Exams will only be administered at PSI/AMP testing centers and are by appointment only. The following PSI/AMP testing centers are available in Massachusetts: Holyoke, Saugus, and Framingham.

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.
