# Pierce v. Society of Sisters — AP Gov Definition

## Definition

Pierce v. Society of Sisters (1925) is a Supreme Court case that struck down an Oregon law requiring all kids to attend public school, ruling that the 14th Amendment's Due Process Clause protects parents' right to direct their children's education. It's an early building block of substantive due process in AP Gov Topic 3.9.

## What It Is

In 1922, Oregon passed a law requiring every child to attend *public* school, which would have effectively shut down private and religious schools. The Society of Sisters, a Catholic order that ran private schools, sued. In **Pierce v. Society of Sisters (1925)**, the [Supreme Court](/ap-gov/key-terms/supreme-court "fv-autolink") unanimously struck the law down, holding that it violated the Fourteenth Amendment's Due Process Clause by interfering with the liberty of parents to direct the upbringing and education of their children.

Here's why this case shows up in [AP Gov](/ap-gov "fv-autolink") even though it's about schools, not bedrooms or medical decisions. Pierce is one of the earliest examples of **[substantive due process](/ap-gov/unit-3/amendments-due-process-right-privacy/study-guide/u7DOoNxO7hTzKLyQwNjr "fv-autolink")**, the idea that "liberty" in the 14th Amendment protects certain fundamental rights that aren't explicitly written anywhere in the Constitution. The right of parents to choose their kids' education is an **unenumerated right**. The Court protected it anyway. That move, recognizing rights the text never names, is exactly the reasoning later courts used to build the right to privacy.

## Why It Matters

Pierce lives in **[Unit 3](/ap-gov/unit-3 "fv-autolink") (Civil Liberties and Civil Rights), Topic 3.9 (Amendments: Due Process and the Right to Privacy)** and directly supports learning objective **AP Gov 3.9.A**, which asks you to explain how substantive due process limits the government from infringing on [individual rights](/ap-gov/key-terms/individual-rights "fv-autolink"). The essential knowledge for 3.9 says the Court has recognized constitutionally protected rights not listed in the Bill of Rights, and that justices defend these unenumerated rights using arguments like implication from other amendments and the Ninth Amendment. Pierce is a perfect illustrative case for that idea. Family and parental rights appear nowhere in the constitutional text, yet the Court found them inside the word "liberty." If you can explain Pierce, you can explain the entire logic of substantive due process, which is the backbone of Griswold, Roe, and the modern privacy debate.

## Connections

### Meyer v. Nebraska (Unit 3)

Meyer (1923) struck down a ban on teaching foreign languages two years before Pierce, and Pierce's constitutional reasoning was built directly on Meyer's [precedent](/ap-gov/key-terms/precedent "fv-autolink"). Together they established that 14th Amendment "liberty" covers family and educational choices, decades before anyone said the word "privacy."

### Right to Privacy and Griswold v. Connecticut (Unit 3)

When the Court recognized a constitutional right to privacy in Griswold (1965), it cited Pierce as proof that the Court had long protected [unenumerated rights](/ap-gov/key-terms/unenumerated-rights "fv-autolink") around family life. Think of Pierce as one of the first bricks in the privacy wall that Topic 3.9 is built on.

### [Dobbs v. Jackson Women's Health Organization (Unit 3)](/ap-gov/key-terms/dobbs-v-jackson-womens-health-organization)

Dobbs (2022) overturned Roe and narrowed substantive due process for abortion, but the [majority opinion](/ap-gov/key-terms/majority-opinion "fv-autolink") specifically said its reasoning didn't disturb cases like Pierce. That contrast is exactly the kind of nuance an MCQ can test about how far the rollback of privacy rights actually goes.

### [Wisconsin v. Yoder (Unit 3)](/ap-gov/key-terms/wisconsin-v-yoder)

Yoder, a required AP Gov case, let Amish parents pull their kids from school after 8th grade on free exercise grounds. It applied the same Pierce-style logic that parents, not the state, get the final say in their children's upbringing.

## On the AP Exam

Pierce is not one of the 15 required Supreme Court cases, so you won't be asked to recite its facts cold. It shows up as an illustrative case for Topic 3.9, and multiple-choice questions tend to test three things: the precedent chain (Pierce built on Meyer v. Nebraska and was later applied in cases like Griswold to expand family privacy protections), who brought the challenge (the Society of Sisters, a Catholic order operating private schools), and how the case contributed to the development of privacy rights. No released FRQ has used Pierce verbatim, but it's exactly the kind of non-required case the SCOTUS comparison FRQ can hand you in the prompt, asking you to connect its substantive due process reasoning to a required case like Wisconsin v. Yoder. Your job is to use it as evidence that the Court protects unenumerated rights under the 14th Amendment.

## Pierce v. Society of Sisters vs Meyer v. Nebraska

Both are 1920s substantive due process cases about education, so they blur together. Meyer (1923) struck down a Nebraska law banning foreign-language instruction; Pierce (1925) struck down an Oregon law banning private schools entirely. Meyer came first and established the precedent; Pierce extended it from what schools can teach to whether parents can choose non-public schools at all.

## Key Takeaways

- Pierce v. Society of Sisters (1925) struck down an Oregon law requiring all children to attend public school, protecting parents' right to choose private or religious education.
- The Court grounded the decision in the 14th Amendment's Due Process Clause, making Pierce an early example of substantive due process protecting an unenumerated right.
- The case was brought by the Society of Sisters, a Catholic order whose private schools would have been wiped out by the Oregon law.
- Pierce built on the precedent of Meyer v. Nebraska (1923) and was later cited in Griswold v. Connecticut to support the constitutional right to privacy.
- Dobbs (2022) narrowed substantive due process for abortion but explicitly left Pierce-style family rights intact, a distinction the exam can test.

### What did Pierce v. Society of Sisters decide?

In 1925, the Supreme Court unanimously struck down an Oregon law requiring all children to attend public schools, ruling that the 14th Amendment's Due Process Clause protects parents' liberty to direct their children's education, including choosing private or religious schools.

### How is Pierce v. Society of Sisters different from Meyer v. Nebraska?

Meyer (1923) struck down a ban on teaching foreign languages; Pierce (1925) struck down a ban on private schools altogether. Pierce's reasoning was built directly on Meyer's precedent, and together they anchor early substantive due process.

Because it protected an unenumerated right (parents directing their children's upbringing) under the 14th Amendment's liberty guarantee. Griswold v.
