Constitutional Law II
Religion in the Public Schools
For religion in the public schools, the Court has used the endorsement test, coercion test, and voluntariness test.
Children can be released from school for religious activities as long as the activity is off-campus.
Prayer is always prohibited under the coercion test or endorsement test unless it is completely voluntary and not coordinated or aided by the school.
Having religious elements such as creationism or the Ten Commandments in the school's curriculum will basically always be struck down as a violation of the first prong of the Lemon test—having a secular purpose.
