How to Become a Fully Registered Professional Sanitarian (RPS) and/or Environmental Specialist (RPES) by Reciprocity

All new applications for Full registration by reciprocity must include the following:

  1. Completed Application for Full Registration, selecting the option for “Reciprocity”
  2. Completed Affidavit of Lawful Presence
  3. Copy of current equivalent registration from a state or entity whose registration laws are reciprocal with Oklahoma's
  4. Payment to “Oklahoma State Department of Health” or “OSDH,” including:
    1. $25.00 for RPS or RPES
    2. $50.00 if applying for both RPS and RPES

Please do not email or fax applications ahead of payment.  This does not expedite processing time.

All items should be submitted together in a single envelope, to:

Mail (pay by check or money order)

Oklahoma State Department of Health
Sanitarian & Environmental Specialist Program
PO Box 268815
Oklahoma City, OK 73126-8815

In Person (pay by check, money order, cash, or credit/debit card)

Oklahoma State Department of Health
1000 NE 10th Street, First Floor
Oklahoma City, OK 73117

(Teller windows are open Monday-Friday 8:30 am to 4:00 pm, and closed on weekends and state holidays.)







If any items are missing, the applicant will be notified, generally via email, that the application cannot be processed until all required items are received.

If an applicant does not qualify for reciprocity, they will be notified via email or postal mail that they may apply for a regular Full or In-Training registration by examination.

If all items are received and the applicant qualifies, the applicant will receive a letter via email or postal mail that their application has been scheduled for review at the next available Advisory Council meeting.  The letter will advise them of the time, date, and location of the meeting; however, the applicant is not required to attend.  Registration certificates and wallet cards are generally mailed out by the following business day.
