This booklet provides a history of teacher retirement benefits in the state of Texas from 1937-97, offering highlights of important state legislation related to retirement and its benefits. In 1936, Texas citizens approved an amendment to the Texas constitution establishing a retirement system for public school employees. Enacting legislation passed by the 45th Texas legislature put the Teacher Retirement System of Texas in business in 1937. The legislation limited membership to persons employed in professional and business administration, supervision, and instruction. Over the years, membership has been extended and retirement benefits have been increased. Various changes in retirement law have provided major benefit improvements to members. Legislation has also altered how benefits are paid, how much the state contributes, member contributions, survivor payments, disability payments, and annuity increases. (SM)
