Texas Registered Sanitarian Examination
On this page:
TDLR administers the Registered Sanitarian exam through our third-party vendor, PSI, at their many locations throughout Texas.
Upon TDLR approval of eligibility, PSI will send you an email confirmation with instructions for scheduling an appointment to take the examination. (If an email address was not provided to TDLR at the time of application, you will receive a postcard via U.S. Mail from PSI with scheduling information).
Scheduling an Exam
If you are eligible for examination, then you can contact PSI via the internet 24 hours a day at www.psiexams.com or by phone at (800) 733-9267 to schedule your exam date.
Eligible candidates may schedule an exam time that is convenient to them. A Candidate Information Bulletin (PDF) including the exam sites and scheduling information is posted on TDLR's web site.
