The Washington State Board of Registered Sanitarians was established in 1982 as an independent organization to serve the needs of environmental health practitioners in Washington State.

The Board manages testing and certification of new Registered Sanitarians in Washington State and provides continuing education support for existing Registered Sanitarians.

REHS/RS exams are now computer-based and administered through the  Pearson VUE system.  Pearson VUE testing sites are located throughout Washington state.  For more information, please contact the Executive Secretary.
