What Are the Required Supreme Court Cases for AP Gov?
The AP Government curriculum focuses on a specific set of Supreme Court cases that illustrate key constitutional principles. These cases are chosen because they address major themes like federalism, civil rights, due process, and the balance of power between government branches. Think of them as the “greatest hits” of constitutional law.
Why These Cases?
The College Board selects cases that show how the Supreme Court interprets the Constitution in real-world situations. They’re not just about the rulings themselves but the reasoning behind them. To give you an idea, Marbury v. Madison isn’t just about judicial review — it’s about how the Court established its own power to check the other branches.
How Many Do You Need to Know?
You don’t need to memorize every case in the textbook. The AP exam typically emphasizes around 15–20 key cases. Worth adding: the rest? Practically speaking, these are the ones you’ll see referenced in essays and practice questions. They’re supporting characters in the story.
Why These Cases Matter (And What Happens When You Don’t Know Them)
Understanding these cases isn’t just about passing a test. Now, it’s about grasping how the Supreme Court has shaped the United States. Take Brown v. Board of Education, for instance. Without knowing its impact on desegregation, you can’t fully appreciate the civil rights movement or modern debates about education equity.
But here’s what really matters for your exam: these cases are the building blocks of FRQ prompts. Now, if you don’t know Gideon v. Worth adding: wainwright, how will you explain the right to counsel in a criminal justice essay? But if you haven’t studied McCulloch v. Maryland, how can you discuss federal power versus state authority?
The short version is this: the AP exam rewards students who can connect cases to constitutional principles. It’s not enough to know the case names — you need to understand their significance and how they interact with each other.

These rulings collectively demonstrate that constitutional law is not static; it adapts to societal changes, technological advances, and shifting political philosophies. As new challenges arise—whether in privacy, technology, or social justice—the Supreme Court will once again be called upon to interpret the Constitution’s enduring principles for the next generation.
