Members of religious orders are considered employees even though the order may have elected to provide Social Security coverage for its members directly; if their positions meet the 600-hour standard (see 3.20 A. General Requirements for IMRF Coverage), they are covered by IMRF. The only exception is when the religious order and the district arrange for the service by a member of an order, and the order designates one of its members to perform the service for the district. In that case, the member is not covered by IMRF.
