Because "teachers" in these entities are members of the MTRS irrespective of any provision of M.G.L. c. 32, a "teacher" in these entities is hereby defined as one who either holds the title of teacher, meets all four of the eligibility criteria set forth in 807 CMR 4.02(1) above, or works in a position that would be eligible for MTRS membership if it were performed in a Massachusetts public school; and(c) Any member in service of the MTRS whose employment status becomes less than half-time without an intervening separation from service as defined in 807 CMR 4.01(1) above. For example, a full-time teacher whose position in the same district is reduced to 40%.Amended by Mass Register Issue 1467, eff. 4/15/2022.
