TMSCA is an organization formed by Texas math and science teachers to promote excellence in math and science through competition. It was formed in 1981 to promote uniformity in the practice meets held to prepare students for University Interscholastic League competition in the spring. Through its efforts grade-level competition is now the norm at practice meets. Team competition, originally promoted at practice meets, is now included in most of the University Interscholastic League's academic events.
