Perfect. In this case, member schools are not conducting nor invoking anything. It is the students who have the right to voluntarily do so.

Students retain their constitutional rights of free speech and expression, including the right to pray and share personal beliefs, while on their public school campuses. Under the Tinker standard, school officials may restrict protected student speech only if it "materially and substantially interferes with appropriate discipline." School officials may not prevent students from gathering together for prayer and religious discussion on school grounds, provided that students do so in a non-disruptive manner during non-instructional time. Non-instructional time would be immediately before and after school, at lunchtime, or any other "free" time when students are permitted to talk and mingle with peers on campus.

This is exactly what this will be. Sometime during warm-ups, a voluntary prayer will be offered to God.

Is this country great or what?
