(1) To ensure that the school district does not discriminate against a student’s publicly stated voluntary expression of a religious viewpoint, if any, and to eliminate any actual or perceived affirmative school sponsorship or attribution to the district of a student’s expression of a religious viewpoint, if any, a school district shall adopt a policy, which must include the establishment of a limited public forum for student speakers at all school events at which a student is to publicly speak. The policy regarding the limited public forum must also require the school district to:

(a) Provide the forum in a manner that does not discriminate against a student’s voluntary expression of a religious viewpoint, if any, on an otherwise permissible subject;

(b) Provide a method, based on neutral criteria, for the selection of student speakers at school events and graduation ceremonies;

(c) Ensure that a student speaker does not engage in obscene, vulgar, offensively lewd or indecent speech; and

(d) State, in writing, orally, or both, that the student’s speech does not reflect the endorsement, sponsorship, position or expression of the district.

(2) The school district disclaimer required by subsection (1)(d) of this section must be provided at all graduation ceremonies. The school district must also continue to provide the disclaimer at any other event in which a student speaks publicly for as long as a need exists to dispel confusion over the district’s nonsponsorship of the student’s speech.

(3) Student expression on an otherwise permissible subject may not be excluded from the limited public forum because the subject is expressed from a religious viewpoint.

(4) All school districts shall adopt and implement a local policy regarding a limited public forum and voluntary student expression of religious viewpoints. If a school district voluntarily adopts and follows the model policy governing voluntary religious expression in public schools as provided by subsection (5) of this section, the district is in compliance with the provisions of this chapter covered by the model policy.

(5) Model policy governing voluntary religious expression in public schools. — In this section, “model policy” means a local policy adopted by the school district that is substantially similar to the following:

(a) Football games;

(b) Any other athletic events designated by the district;

(c) Opening announcements and greetings for the school day; and

(d) Any additional events designated by the district, which may include, without limitation, assemblies and pep rallies.
