The Lemon Test, a three-pronged approach to interpreting the Establishment Clause, was created in 1971 in the case Lemon v. Kurtzman. The test was used for nearly four decades to evaluate whether a law or government activity violated the Establishment Clause of the First Amendment. The Lemon Test was modified in 1997 in the case Agostini v. Felton, and while it was not explicitly overturned, it was largely abandoned by 2022 in favour of the historical practices and traditions test.

What You'll Learn

Lemon v. Kurtzman (1971)
The court ruled that both programs were unconstitutional, as they failed the third prong of the test. While the programs met the secular purpose criterion, it was unclear whether they met the second criterion, as the aid could be used for religious purposes. The court, however, determined that the programs failed the third criterion as they excessively entangled state administrators with parochial schools, requiring constant government monitoring of lesson plans, instruction, and expenditures.
The Lemon Test became an influential legal doctrine, applied in cases involving government funding of religious institutions and the promotion of religious messages. However, it has faced criticism from several justices, who argue that it requires a strict separation between church and state. Despite its influence, the test has been modified and, by 2022, was largely abandoned by the Supreme Court.

The three-pronged test
The Lemon Test, also known as the three-pronged test, was created in 1971 following the Supreme Court's ruling in Lemon v. Kurtzman. The Lemon Test was used for nearly four decades to evaluate whether a law or government activity violated the Establishment Clause of the First Amendment.
The three prongs of the test are as follows:
- The first prong examines the purpose of the law to determine if it has a secular purpose.
- The second prong looks at the primary effect of the law to assess whether it has a predominantly secular effect.
- The third prong evaluates whether the law fosters "excessive entanglement" between the government and religion.
If a law fails any one of these tests, it is considered a violation of the Establishment Clause and is deemed unconstitutional. The Lemon Test was influential in shaping legal doctrine and was applied in several significant cases, including Santa Fe Independent School Dist. v. Doe (2000) and Kitzmiller v. Dover (2005). However, by 2022, the court had largely abandoned the Lemon Test, with some justices criticizing it for its shortcomings and inability to resolve certain Establishment Clause cases.
Another notable example of a three-pronged test is the Miller Test, developed in 1973 in the case of Miller v. California. This test is used to determine whether speech or expression can be labeled obscene and therefore not protected by the First Amendment. The three prongs of the Miller Test are:
- Whether the average person, applying contemporary community standards, would find that the work, as a whole, appeals to the prurient interest.
- Whether the work depicts or describes sexual conduct or excretory functions in a patently offensive manner, as specifically defined by applicable state law.
- Whether the work, as a whole, lacks serious literary, artistic, political, or scientific value.
The Miller Test has faced criticism for its potential to suppress speech and expression, particularly in the age of the internet, where determining "community standards" has become increasingly challenging.

The Establishment Clause
The Lemon Test, created in 1971, was used for nearly four decades to evaluate whether a law or government activity violated the Establishment Clause. The three-pronged test examined whether a law or activity had a secular purpose, a predominantly secular effect, and did not foster "excessive entanglement" between government and religion. However, by 2022, the Supreme Court had largely abandoned the Lemon Test, with some justices criticising it for its shortcomings and failure to resolve certain Establishment Clause cases.

Criticism of the Lemon test
The Lemon Test, which was used for nearly four decades to evaluate whether a law or government activity violated the establishment clause of the First Amendment, has been criticised by many justices and legal analysts. The test was largely abandoned by 2022.
One criticism of the Lemon Test is that it is highly subjective and inconsistent. Critics argue that the test exhibited a great deal of inconsistency, which filters down to the legislatures that pass such programs and the lower courts that evaluate them. Justices Thomas and Alito have heavily criticised the test in the past, and Justice Gorsuch called it a "dog's breakfast". Chief Justice Roberts and Justice Kavanaugh agreed that it was too subjective to be useful.
Another criticism is that the test is ahistorical and too abstract. In Kennedy v. Bremerton School District (2022), Justice Gorsuch's majority opinion criticised the test as being too abstract and ahistorical, instead emphasising "reference to historical practices and understandings". This decision was viewed as the official end of the Lemon Test.
The test has also been criticised for creating a constitutional catch-22 for governments seeking to help religious schools. Justice Sandra Day O'Connor argued that the second criterion of the test required the government to monitor teachers in religious schools to ensure they did not provide religious instruction, while the third criterion prohibited the government from monitoring religious schools in ways that created excessive entanglement.
The abandonment of the Lemon Test has also been criticised for encouraging a proliferation of legislation favouring an accommodationist standpoint of religion in public education. Some states have pushed the boundaries of what will be approved, leading to a more originalist and accommodationist view of religious presence in public education.

The Lemon test's abandonment
The Lemon Test, a three-pronged test, was created in 1971 following the Supreme Court's ruling in Lemon v. Kurtzman. The test was used for nearly four decades to evaluate whether a law or government activity violated the Establishment Clause of the First Amendment, which prohibits the government from establishing a religion.
The Lemon Test
Under the Lemon Test, the courts would determine whether a law or government activity complied with the Establishment Clause by examining:
- The purpose of the aid: whether it had a secular legislative purpose.
- The effect of the aid: whether its primary effect advanced or inhibited religion.
- The entanglement: whether it created "excessive governmental entanglement" with religion.
Criticism of the Lemon Test emerged over the years, with some justices arguing that it required a strict separation between church and state. The test was also criticised for being too abstract and ahistorical, with Justice Samuel Alito stating that "as Establishment Clause cases involving a great array of laws and practices came to the Court, it became more and more apparent that the Lemon test could not resolve them."
The Supreme Court began to move away from rigidly applying the Lemon Test, instead treating its three factors as "helpful signposts" in the Establishment Clause inquiry. In 2019, the Court's decision in American Legion v. American Humanist Association limited the applicability of the Lemon Test, suggesting that it would not be applied to evaluate "longstanding monuments, symbols, and practices."
By 2022, the Court had largely abandoned the Lemon Test as a way to measure compliance with the First Amendment's prohibition on the government's establishment of religion. In Kennedy v. Bremerton, a case involving a high school football coach's group post-game prayers, Justice Neil Gorsuch ruled that the Establishment Clause "must be interpreted by 'reference to historical practices and understandings.'" The ruling in Kennedy also defanged the coercive test, an essential component of Establishment Clause jurisprudence.
The abandonment of the Lemon Test has had implications for the enforcement of the Establishment Clause in schools, with a proliferation of legislation favouring an accommodationist standpoint of religion in public education.
