Type of plan
The MTRS is a defined benefit retirement plan that operates as a qualified plan under section 401(a) of the Internal Revenue Code. Under the MTRS defined benefit plan, retirement benefits are determined according to a set formula, and the amount is guaranteed regardless of fluctuations in the pension fund's performance; retirement benefits are payable for a retiree’s lifetime.
The MTRS is governed by the Massachusetts Teachers’ Retirement Board, which is comprised of seven members.
Eligibility for membership in the MTRS is primarily determined by the definition of "teacher" in M.G.L. c. 32, §1. However, other sections of Chapter 32, Chapter 71 §89(y), as well as the MTRS regulation on membership eligibility also set out criteria for membership. In general, individuals employed as teachers or administrators in a Massachusetts public school outside of the City of Boston, or in any educational collaborative or charter school in Massachusetts (and who meet the eligibility requirements) are required to become members of the MTRS.
