Michigan Public School Employees Retirement System (MPSERS)

The Michigan Public School Employees Retirement System (MPSERS) is a statewide public employee defined benefit plan qualified under section 401(a) of the Internal Revenue Service Code operating under the provisions of Michigan's Public Act 300 of 1980, as amended (Michigan Compiled Laws 38.1301 et seq.).

The plan is administered by the Office of Retirement Services (ORS).

MPSERS collects and compiles employee wage, contribution, and service information. Upon retirement, the annual benefit is based on a formula that multiplies the employees' final average compensation by a pension factor times the years of service.

  • Hourly and part-time salaried employees eligible for MPSERS at CMU automatically participate in MPSERS as their retirement plan.
  • Full-time salaried employees eligible for MPSERS must make a one-time irrevocable choice in regard to their retirement plan, within 90 days of eligibility.
  • Exception: Any employee who is also a CMU Retiree and/or a MPSERS retiree (from any institution, and drawing a MPSERS pension) will not be eligible for any retirement benefit.


If you’re eligible for MPSERS, the University will start contributions as of your date of hire. Salaried employees must make an irrevocable choice within 90 days as to whether to stay with MPSERS plan or go to the ORP. If no choice is made within 90 days, you will automatically remain in MPSERS. Non-salaried employees will remain in MPSERS.
