Engel v. Vitale, 370 U.S. 421 (1962), was a landmark United States Supreme Court case in which the Court ruled that it is unconstitutional for state officials to compose an official school prayer and encourage its recitation in public schools, due to violation of the First Amendment. The ruling has been the subject of intense debate.

Epperson v. Arkansas, 393 U.S. 97 (1968), was a landmark United States Supreme Court case that invalidated an Arkansas statute prohibiting the teaching of human evolution in the public schools.[1] The Court held that the First Amendment to the United States Constitution prohibits a state from requiring, in the words of the majority opinion, "that teaching and learning must be tailored to the principles or prohibitions of any religious sect or dogma." The Supreme Court declared the Arkansas statute unconstitutional because it violated the Establishment Clause of the First Amendment. After this decision, some jurisdictions passed laws that required the teaching of creation science alongside evolution when evolution was taught. These were also ruled unconstitutional by the Court in the 1987 case Edwards v. Aguillard.

Edwards v. Aguillard, 482 U.S. 578 (1987), was a United States Supreme Court case concerning the constitutionality of teaching creationism. The Court considered a Louisiana law requiring that where evolutionary science was taught in public schools, creation science must also be taught. The constitutionality of the law was successfully challenged in District Court, Aguillard v. Treen, 634 F. Supp. 426 (ED La.1985), and the United States Court of Appeals for the Fifth Circuit affirmed,

Aguillard v. Edwards, 765 F.2d 1251 (CA5 1985). The United States Supreme Court ruled that this law violated the Establishment Clause of the First Amendment because the law was specifically intended to advance a particular religion. In its decision, the court opined that "teaching a variety of scientific theories about the origins of humankind to school children might be validly done with the clear secular intent of enhancing the effectiveness of science instruction."
