School treasurers are considered employees. If the position meets the 600-hour standard, the school treasurer is an IMRF participating member. If a person is a school treasurer for more than one school district, the combined hours must be used in applying the 600-hour standard.
Exception: Licensed school administrators who are Board of Education Treasurers (see 3.40 C. Teaching Earnings).
Township School Treasurers in Cook County and their employees may participate in IMRF as governmental units independent of school districts.
