Explanation:

The Warren Court's key ruling on school prayer (Engel v. Vitale, 1962) focused on prohibiting officially sponsored, school-led prayers in public schools, as this violated the Establishment Clause of the First Amendment. It did not ban private, individual, or small-group voluntary prayers.
