Missouri Code of State Regulations
Title 16 - RETIREMENT SYSTEMS
Division 10 - The Public School Retirement System of Missouri
Chapter 4 - Membership and Creditable Service
Section 16 CSR 10-4.010 - Membership Service Credit

(1) Membership service credit for full-time employment will be calculated based on the following ratio beginning July 1, 1997: The actual compensation received by the member for the school year divided by the annual compensation expected to be paid for that full-time position for a complete school year, as reflected on the beginning of the year report from the employer (or as later amended). Both the numerator and denominator will be determined without regard to the career ladder and medical benefits that are otherwise included in compensation. Credit resulting from the above calculation shall be rounded to the nearest hundred-thousandth. Not more than one (1) year of membership service credit will be allowed for any school year.

(2) Where credit is allowed by law for part-time employment, the credit will be calculated based on the following ratio beginning July 1, 1997: The actual compensation received by the member for the school year divided by the annual compensation that would be paid for that position on a full-time basis for a complete school year, as reflected on the beginning of the year report from the employer (or as later amended). Both the numerator and denominator will be determined without regard to the career ladder and medical benefits that are otherwise included in compensation. Credit resulting from the above calculation shall be rounded to the nearest hundred-thousandth. Not more than one (1) year of membership service credit will be allowed for any school year.

(3) When a member terminates employment with an employer included in the retirement system before the end of a school year, the maximum credit that may be received for that school year for employment with such employer will be calculated based on the portion of the school year completed before termination of membership. When a member begins employment with an employer included in the retirement system after the start of a school year, the maximum credit that may be received for that school year for employment with such employer will be calculated based on the portion of the school year completed after starting covered employment. Provided, however, that the beneficiary of a deceased member may elect to have membership service credit calculated pursuant to section (1) of this rule if such beneficiary is eligible or would become eligible for benefits pursuant to section 169.070.3(2) or 169.075, RSMo. In no event will benefit payments commence prior to July 1 if the member is allowed one (1) year of membership service credit.
