1. Unit Overview & The Big Picture
Unit 3, “Civil Liberties and Civil Rights,” makes up roughly 13–18% of the multiple-choice exam and is the unit most
likely to anchor the required SCOTUS Comparison FRQ, since it contains more required Supreme Court cases than any
other unit.
Civil liberties are protections FROM government interference (“the government cannot do X to you”). Civil
rights are protections FROM discrimination, often requiring government action to secure equal treatment
(“the government must ensure X for you”). Confusing the two costs points on nearly every FRQ in this unit.
This unit is dense with required Supreme Court cases — the exam expects you to know the facts, issue, holding, and
reasoning of each one well enough to compare it to an unfamiliar, non-required case with similar facts (the SCOTUS
Comparison skill).
The 3 Things Your Teacher Wants You to Walk Away Knowing:
• The Bill of Rights originally restrained only the FEDERAL government; selective incorporation is the ongoing
process by which the Supreme Court has applied most of those protections to STATE governments too, via the
14th Amendment's Due Process Clause.
• Rights are rarely absolute — the Court constantly balances individual freedom (e.g., speech, religion) against
competing interests (public order, national security, others' rights), and the specific TEST the Court uses (clear
and present danger, Lemon test, strict scrutiny) determines the outcome.
, • Civil rights progress has come through a mix of Supreme Court rulings, legislation (Civil Rights Act of 1964,
Voting Rights Act of 1965), and grassroots social movements — not from any single source alone.
2. Key Concepts (Official College Board Framework)
The College Board organizes Unit 3 into 13 topics (3.1–3.13).
Topics 3.1–3.2 — The Bill of Rights & Religion
• The Bill of Rights (first 10 amendments) protects individual liberties; the Establishment Clause bars government
endorsement of religion, while the Free Exercise Clause protects individuals' right to practice their religion.
Topics 3.3–3.5 — Speech, Press & the Second Amendment
• Freedom of speech and press are not absolute; the Court has developed specific tests to determine when
speech can be restricted (e.g., inciting imminent violence, obscenity, defamation).
• The Second Amendment protects an individual right to bear arms (District of Columbia v. Heller), though
reasonable regulations remain permissible.
Topics 3.6–3.8 — Selective Incorporation & Due Process
• Selective incorporation is the process by which the Supreme Court has applied most Bill of Rights protections to
the states via the 14th Amendment's Due Process Clause, on a case-by-case basis.
• Rights of the accused (4th, 5th, 6th, 8th Amendments) protect against unreasonable searches, self-
incrimination, and guarantee the right to counsel and a speedy trial.
Topics 3.9–3.13 — Civil Rights
• The 14th Amendment's Equal Protection Clause is the constitutional basis for civil rights claims against
discrimination by state governments.
• Social movements (civil rights movement, women's rights movement) have used protest, litigation, and
legislative advocacy to expand civil rights over time.
• Affirmative action policies, intended to remedy historical discrimination, remain a contested application of the
Equal Protection Clause, tested through cases balancing diversity goals against equal treatment.
3. Deep Dive: The First Amendment — Religion
Religion questions hinge on correctly identifying which of the two religion clauses applies to a given scenario.
Clause What It Protects Required Case
Establishment Prevents government from establishing or Engel v. Vitale (1962) — school-
Clause favoring an official religion, or excessively sponsored prayer in public schools is
entangling itself with religion unconstitutional, even if voluntary and
non-denominational
Free Exercise Clause Protects an individual's right to practice their Wisconsin v. Yoder (1972) — compelling
religion without undue government Amish students to attend school past 8th
interference grade violated their free exercise rights
A common exam scenario asks you to determine whether a government action violates the Establishment Clause
(government promoting/endorsing religion) or the Free Exercise Clause (government restricting an individual's
religious practice) — these require opposite analyses, so identify which clause is actually implicated first.
