A public school mess in houston...

That's already been decided. You lost. Get used to it.

The Court's decision in this case established the "Lemon test", which details the requirements for United States legislation concerning religion. It consists of three prongs:

1. The government's action must have a legitimate secular purpose;
2. The government's action must not have the primary effect of either advancing or inhibiting religion; and
3. The government's action must not result in an "excessive entanglement" with Religion.

If any of these three prongs is violated, the government's action is deemed unconstitutional under the Establishment Clause of the First Amendment to the United States Constitution.
