The System is responsible for investing funds under its stewardship and for delivering benefits to members as authorized by the Texas Legislature. TRS is a defined benefit plan, with retirement benefits determined by a pre-established formula. The trust fund is sustained principally by three sources — contributions by members during their working careers, contributions by the state, and investment revenues.
TRS is the largest public retirement system in Texas in both membership and assets. The agency serves 1,414,607 participants — 1,051,425 are public and higher education members, and 363,182 are retirement recipients. As of August 31, 2014, System net assets totaled $132.8 billion.
TRS has been serving the needs of Texas public education employees for more than 75 years. In November 1936, voters approved an amendment to the Constitution of Texas creating a statewide teacher retirement system. With the passage of enabling legislation passed in 1937, TRS was officially formed.
