The Establishment Clause of the First Amendment to the U. S. Constitution sets forth the separation of church and state required in public schools. That clause has been interpreted in a lengthy history of U. S. Supreme Court decisions.

In this article, the authors summarize relevant decisions of the Supreme Court and extend the discussion to the Fifth Circuit Court of Appeals' decision in "Doe v. Duncanville Independent School District" in which a public school coach led team members in prayer prior to a school-sponsored athletic contest.
