• IMRF Participation

    All eligible employees must participate in the Illinois Municipal Retirement Fund (IMRF) System. Eligible employees are currently defined by law as individuals who are employed for a minimum of 600 hours over a twelve-month period. The employee’s share of the IMRF contribution is deducted from each employee paycheck. The Board of Education will comply with all current applicable rules and regulations governing IMRF contributions. Additional information about the IMRF Pension system can be accessed on the IMRF website.


    Your “Tier” determines your IMRF benefits. Your tier is determined by the first date you began participating in IMRF or certain Illinois reciprocal systems.

    Regular Plan

    Most IMRF members participate in the Regular plan. Regular plan members work for local units of government that participate in IMRF. Government types include school districts, cities, villages, townships, counties (except Cook), fire protection districts, library districts, and park districts.

    If you first participated in IMRF or reciprocal system (except Judges or General Assembly retirement systems):

    • Before January 1, 2011, you are in Tier 1
    • On or after January 1, 2011, you are in Tier 2
