All officers are members of the Oklahoma State Police Pension and Retirement System. The retirement system allows officers to have a full retirement after 20 years of service. Retirement is listed at 50% of the officer’s base pay, adding 2.5% for every year spent after 20 years of service, maxing out at 30 years. This retirement is guaranteed at 20 years and is not age-based. The retirement system also allows vested officers to leave after 10 years of service. The officer can draw 25% pay but not until reaching 20 years of service or when the officer turns 50 years of age (whichever option is later).
