No, it is legal in Texas to carry a firearm on a campus of higher education so long as the individual is licensed to carry in the state per the Texas Government Code section 411.2031
Students may prosecute institutions denying their right to carry a concealed firearm if they are a license holder, incurring civil penalty charges of over 1,000 for the first offense and over 10,000 for future offenses. Students should however look towards petitioning the right to carry on campus without a license and contact state government officials in request for legislative change.
The student would not be penalized if they are licensed to conceal carry within the state. Exclusions exist only within the vicinities of sporting events, areas where K-12 education is conducted, and some laboratories.
The university could petition the state government in request that campus carry be permitted for non-license holders.
