The Advanced Water Treatment Operator™ (AWTO®) certification computer-based delivery options are limited during shelter-in-place orders during the COVID-19 pandemic.
Professional testing centers operated by PSI are located throughout CA, NV and elsewhere. They are preparing to reopen as local and state jurisdictions permit.
The safety and disinfection processes are being updated.
AWTO Exam Applications are Welcome
We are still accepting AWTO exam applications. We are not processing applications until we get the okay to do so by PSI.
Once approved you have one year to take the exam before your application expires. Any necessary adjustments due to COVID-19 will be announced here.
