school employees present from other states or from educational institu- tions which are not covered by this act, school service records which are, in the judgment of the board, comparable to the service requirements of this act, such outside service records shall be counted in determining the record of twenty years’ service required herein for eligibility, but not in determination of service annuities. This act shall not apply to any employees while they are members of a separate school retirement system operated by the State of Kansas or any of its governmental sub- divisions. A majority of all members participating in any such separate school retirement system may make application to the board for permis- sion to come within the provisions of this act by a petition duly signed and verified, approved by the local board of education, and filed with the board. The board is hereby authorized to promulgate rules, regulations and plans for the inclusion of such retirement systems under the pro- visions of this act, or the board may draft plans for the inclusion of such systems and present same to the legislature. Sec. 10. As soon as practicable after this act goes into effect, the board shall receive, verify, and formally validate service records as sub- mitted by school employees. So far as possible, reports of school service, of salaries earned, and of dates of birth shall be certified from official records; but when these are not available, the board is authorized and directed to consider other reasonable evidence. Any statement of a date of birth shall be signed under oath by the school employee concerned. The board shall have authority, independently, to secure other evidence affecting service records. Sec. 11. If any school employee shall fail to file any service record required by the board within three months, the board may as penalty increase his deductions to 5% until said service record is properly filed. If any school employee shall delay filing claim for a service annuity, no payment shall ever be made for the period of the delay. SEc. 12. Except as otherwise provided in this act, any school em- ployee who has attained the age of 65 shall be eligible to a school an- nuity, but any employee who retires direct from service may, at his choice, be granted an annuity beginning on any September first from age sixty to age seventy, inclusive. Any annuity granted prior to age 65 shall not be the standard annuity, but shall be the actuarial equiva- lent at attained age. When an annuity is granted to a person past age 65, there shall be no back payments, and said service annuity shall be computed as if the age were 65. All annuities of one hundred twenty dollars or more shall be paid in equal monthly installments beginning on the first of September of that calendar year. Annuities of less than one hundred twenty dollars shall be paid in quarterly or semi-annual installments as the board may direct. No person shall be employed for any school service to which this act applies, after August thirty-first of the year in which he attains age seventy. Nor shall any person be so employed after receiving the first installment of a school annuity, or while receiving a disability annuity provided by this act. The first monthly installments of school annuities shall be paid in January, 1942. 10
