Important COVID-19 Letter from PSI 6/30/2020  

Dear PSI Testing Service Clients,


We hope this message finds each of you healthy and well in these unprecedented times.  As the COVID-19 situation labors on, we are reaching out to you with updates about how PSI test centers are currently operating and to provide some additional resources for your program. 


PSI is continuing to monitor the latest developments associated with the global spread of COVID-19. At their testing centers, they are following strict safety procedures in line with federal, state, and local guidelines as well as guidelines provided by the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).  At all times, PSI’s top priority is the health, safety, and well-being of your candidates, their team, and the entire community that relies on PSI’s solutions and services. Below are some key points highlighting some of the steps that have been implemented at the test centers to ensure safety:


Test Center Safety


  • PSI is now mandating that ALL candidates wear face masks at all times while in the test center.
  • If a candidate fails to bring and wear a face mask during the examination, they will be requested to leave the test site.
  • The health questionnaire will continue to be provided to the candidates prior to the examination.  A copy of the questionnaire is available here.
  • Candidates should complete the questionnaire and bring it with them on their testing day. If a candidate fails to bring the required questionnaire, one will be provided on-site.
  • If a candidate answers, “yes” to any of the first four questions, they will need to reschedule their exam.
  • Candidates will be requested to remove the face mask briefly during check-in to verify identity as well as capture the photograph of the candidate.
  • Candidates may wear gloves during the examination. Gloves will need to be examined by the test site administrator during check-in and check-out.
  • Candidates must dispose of PPE outside of the testing center; they will not be allowed to discard used PPE at the test site. 
  • PSI is focused on safe distancing in the lobby area for the candidates as well as their employees. As a result, candidates may be requested to wait outside of the building or in the hallway until such a time when PSI staff can safely check the candidate in.

PSI Employees

  • Test site administrators are being provided face masks, hand sanitizers, and antibacterial wipes.
  • In addition, all testing equipment will be thoroughly wiped down following each test administration.
  • Test centers will continue to have signage reminding candidates of the social distancing protocols.

More information regarding the safety and sanitation procedures at test sites, as well as frequently asked questions, can be found at the following link:

As always, when your candidates are scheduling (or rescheduling) their exams, PSI encourages the use of the online scheduling system as it will show the most up-to-date test center availability.  If a candidate wishes to call PSI and speak to a customer service representative (CSR), please have them utilize the following number: 833-256-1420. This number is a line for ABC clients and candidates only; as such, hold times for a CSR will likely be decreased.



New VCC Procedures (effective January 2020)
  • First-time certification candidates
    New applicants must complete an Initial Application Form. Once you're determined to be eligible to sit for the D-level exam, you will receive an email from PSI that outlines the information necessary to take the exam, such as your identification number and testing locations. Scheduled online with PSI or call 833-256-1420. There is no time limit to schedule the exam. Take time to study.You will be notified immediately of your test result upon completion of the exam at the testing center.

  • Repeat same level exams
    You must wait 10-14 days for PSI to reset the exam scheduling on the PSI website portals. Exam request forms are no longer needed. Reschedule directly with PSI.

  • Next level exams
    An exam request form is no longer need in order to take an exam for the next level of certification. Schedule the exam directly with PSI. You must complete the new Experience Verification Form before your new certificate will be issued.

  • Experience verification instructions
    In order to document the one year of actual operating experience required for each level of promotion, a supervisor must submit an Experience Verification Form (EVF) for each level of certification requested. You must wait 7-14 business days to apply for the next exam directly with PSI. In order to receive a license upgrade, an EVF must be submitted. Taking and passing the exam alone will not initiate the upgrade process. The Association will not process an EVF or provide a certificate until a passing score has been received from PSI. The required EVF must contain complete information. Incomplete forms will be returned unprocessed.






What is Certification?

The WEASC Voluntary Certification Program for Wastewater Collection System Operators is a tiered professional certification program much like the mandatory certification program for environmental system operators. A Wastewater Collection System Operator prepares for and takes the appropriate level exam, beginning with the "D" level and is awarded that Certification upon successful completion (a score of 70 or above) of the exam. The individual may continue with the process, gaining practical experience and taking exams until the desired certification level is achieved, "A" being the highest possible. Once an individual is certified in Wastewater Collection Systems, they must obtain six hours of continuing education training annually to maintain their license status along with annually renewing their certification through the WEASC Voluntary Certification Program.
