Tenn. Code § 49-6-1805
Students may organize religious student groups, religious clubs, "see you at the pole" gatherings, or other religious gatherings before, during, and after school to the same extent that students are permitted to organize other noncurricular student activities and groups. Religious groups shall be given the same access to school facilities for assembling as is given to other noncurricular groups without discrimination based on the religious content of the students' expression. If student groups that meet for nonreligious activities are permitted to advertise or announce meetings of their groups, then the LEA may not discriminate against groups that meet for prayer or other religious speech. An LEA may disclaim school sponsorship of noncurricular groups and events in a manner that neither favors nor disfavors groups that meet to engage in expressions of faith or religious speech.
