The Lemon Test is necessary to determine whether the establishment clause was violated. This test is used by the United States Supreme Court to decide cases involving the separation of church and state, particularly when it comes to government actions that may promote or inhibit religion. The Lemon Test requires that a law or government action must have a secular purpose, must not advance or inhibit religion, and must not result in excessive entanglement between government and religion.
