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.
