Is it illegal to deny a student to use the bathroom in the state of TX?

In Texas, there is no specific law that explicitly grants students the right to use the bathroom at school; however, denying a student access to the bathroom can be considered a violation of their rights and could potentially lead to legal issues, especially if it impacts their health or well-being. Schools are generally encouraged to allow students to use the restroom as needed, and policies should be in place to accommodate students' needs. If a student feels unfairly denied access, they may have grounds to report the issue to school administrators or seek further assistance.
