The law protects religious dress in school. Generally, schools are allowed to impose dress codes because they have a legitimate interest in instilling discipline, teaching respect for authority, promoting hygiene, and minimizing distraction caused by unusual hair or dress. But the First Amendment and the Texas Religious Freedom Restoration Act (TRFRA) require schools to make exceptions to their dress codes for religious dress. These exceptions are necessary to allow students with sincerely held religious beliefs to freely exercise those beliefs through religious dress. They also allow students to engage in religious speech.
