Any member retiring under the provisions of this chapter or any member retiring under provisions of chapter 169, RSMo, who is a member of the public school retirement system and who is employed by a state agency other than an institution of higher learning, after working continuously until reaching retirement age, shall be credited with all his unused sick leave as certified by his employing agency. When calculating years of service, each member shall be entitled to one-twelfth of a year of creditable service for each twenty-one days of unused accumulated sick leave earned by him. The rate of accrual of sick leave for purposes of computing years of service as this section applies to legislative, executive and judicial employees shall be consistent with the rate of accrual as specified by regulations of the personnel advisory board pursuant to section 36.350, RSMo. Nothing under this section shall allow a member to vest in the retirement system by using such credited sick leave to reach the time of vesting.
