Okla. Stat. tit. 59 § 1467
Each polygraph examiner's license shall be issued for the term of one (1) year and shall, unless suspended or revoked, be renewed annually as prescribed by the Board. A polygraph examiner whose license has expired may at any time within two (2) years after the expiration thereof obtain a renewal license without examination by making a renewal application therefor and satisfying Section 8, subsections 2, 3 and 4. However, any polygraph examiner whose license expired while he was in the federal service on active duty with the armed forces of the United States, or the national guard called into service or training, or in training or education under the supervision of the United States preliminary to induction into the military service, may have his license renewed without examination if within two (2) years after termination of such service, training or education except under conditions other than honorable, he furnishes the Board with an affidavit to the effect that he has been so engaged and that his service, training or education has been so terminated. Section 8, subsections 2, 3 and 4 of this act must also be satisfied.
