theres no texas state because back in the '60s when all the land grant schools were chaning their names the texas agricultural and mechanical college changed to texas a&m (the a&m don't stand for agricultural and mechanical, they're just a link to the past) and moved out of the university of texas system to become its own system. there is a TSU, but its texas southern. theres also a state university system of texas, which includes sam houston state, amongst other school.s
