What this topic is asking
Topic 1.2 (skill CLE-1.B) asks you to identify the kinds of evidence a writer uses and to judge whether that evidence is relevant and sufficient to support a claim. Evidence is what turns an assertion into an argument; choosing the right evidence for the audience and purpose is one of the most analysable choices a writer makes.
Types of evidence
- Facts. Verifiable statements ("the population grew by 40,000 in a decade"). Solid but dry; they establish logos.
- Statistics. Quantified facts ("crime fell 12 percent"). Persuasive to data-minded audiences; watch for cherry-picking.
- Anecdotes. Brief, vivid stories that put a human face on a claim. They build pathos and make abstractions concrete.
- Expert testimony. Statements from authorities or professional bodies. They borrow ethos from the source's credibility.
- Examples and case studies. Specific instances that illustrate or test a claim.
- Analogies. Comparisons that illuminate an unfamiliar idea by likening it to a familiar one. Powerful but only as strong as the likeness.
What makes evidence work
A writer chooses evidence to match the audience. Policymakers expect statistics and expert testimony; a general readership is moved by anecdotes and examples. The strongest arguments mix types so that logos, ethos, and pathos all do work.
Selecting evidence as a rhetorical choice
When you analyze a passage, the writer's choice of evidence is itself the thing to analyze. Ask not only "what type is this?" but "why this evidence, for this audience, in service of this purpose?"
Why this matters for the exam
The synthesis essay (Free Response Question 1) is graded on how well you select and integrate relevant evidence from sources. The rhetorical analysis essay rewards explaining why a writer's evidence suits the audience. Multiple choice questions ask you to name evidence types and judge their relevance. Across all three, the skill is the same: connect evidence to claim and to situation.
Try this
Q1. List four types of evidence a writer might use to support a claim. [Recall]
- Cue. Facts, statistics, anecdotes, expert testimony, examples or case studies, and analogies (any four).
Q2. A writer supports the claim "remote work boosts productivity" with one story about a friend who works from home. Evaluate the evidence. [Short explanation]
- Cue. The anecdote is relevant and vivid but not sufficient: a single story cannot establish a broad claim. The writer needs statistics or studies to make the claim convincing.

AP 2023 (multiple choice, style)1 marksA writer arguing that a city should expand its libraries supports the claim with: a quotation from a librarians' association, a chart of rising visitor numbers, and a story about a child who learned to read at a branch library. These three pieces of evidence are, respectively, (A) statistic, anecdote, expert testimony (B) expert testimony, statistic, anecdote (C) anecdote, expert testimony, analogy (D) analogy, statistic, anecdote (E) expert testimony, analogy, statistic.Show worked answer →
Answer: (B). The skill is naming types of evidence and matching each to its label.
The quotation from a professional body is expert testimony; the chart of visitor numbers is statistical evidence; the story about one child is an anecdote.
Why not the others: an analogy compares two unlike things to illuminate one of them, and none of these does that. Recognizing that a single story is an anecdote, not a statistic, is the trap the question sets.
Markers reward precise identification, since the same passage may mix several kinds of evidence the writer chose deliberately.
AP 2022 (synthesis, style)6 marksCarefully read the following six sources, including any introductory information. Then write an essay that develops a position on whether communities should prioritize green space when planning new housing, synthesizing material from at least three of the sources to support your argument.Show worked answer →
The synthesis essay (Free Response Question 1) is scored on the 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication) and tests whether you can select and integrate relevant evidence from sources.
Thesis (1 point): a defensible position, e.g. "Because green space measurably improves health and cohesion, planners should treat it as infrastructure, not decoration."
Evidence and commentary (4 points): draw on at least three sources, choosing the evidence most RELEVANT to your claim - a public-health statistic, an expert planner's testimony, a community anecdote - and explain how each supports the position. Dumping a quotation without commentary does not score.
Sophistication (1 point): weigh cost or density trade-offs and show your position survives them.
The essay rewards selecting relevant, sufficient evidence and tying it to the claim, which is exactly this topic's skill.
