Okla. Admin. Code § 140:15-9-1
The Board shall have practice oversight authority for all post-doctorate chiropractic specialties. No chiropractic physician shall represent to the public that he/she is a specialist in any area unless said chiropractic physician is registered with the Board. Pursuant to the legislative authority granted to the Board, the Board hereby recognizes the requirements adopted from time to time of the Federation of Chiropractic Licensing Boards' Recognized Chiropractic Specialty Program (FCLB RCSP) as requirements of the Board. The Board, however, reserves the approval authority for all programs based on furtherance of professional development and related areas, and in the interest of the public protection objectives of the Act. The Board shall maintain a registry listing all chiropractic physicians who are approved by the Board.
