• Effective July 1, 2008, a tri-county substitute system called the Central Michigan Substitute System (CMSS) has been formed. This is the result of a unique partnership with the Clinton County Regional Educational Service Agency, Eaton Intermediate School District and Ingham Intermediate School District. EduStaff will become the employer of record and coordinate payroll for all substitute services that were formerly handled by the three counties. EduStaff has established a relationship with AESOP, the automated online substitute calling service, to provide online and telephone acceptance for substitute assignments in our area.

    Most Clinton, Eaton and Ingham districts will be using EduStaff to register and pay substitute teachers. Our substitute teachers are an integral part of our educational system, please read this information, as it will help explain the process to become a registered substitute in our district.

    If you will be teaching with 60+ credit hours OR an expired certificate, you are required to apply for a 150-day permit from the Michigan Department of Education.

    Please note: A 150-day permit is no longer required for those holding a valid Michigan Teaching Certificate and would like to teach outside of a certified subject area.
