What this topic is asking
Topic 1.3 (skill CLE-3.A) shifts you from reading arguments to writing them. It asks you to develop your own defensible claim: an arguable position drawn from the patterns you notice in your evidence. This is the seed of every essay you will write, so getting the claim right is the highest-leverage skill in the course.
What "defensible" means
The word "defensible" does two jobs. It must be arguable (worth defending) and supportable (you can actually defend it). "Social media is technology" is true but not arguable. "Social media has ended human connection" is arguable but indefensible because it is too absolute. "Social media isolates more than it connects" sits in the productive middle.
From observation to claim
A claim does not arrive fully formed. You build it from observations about a subject, then look for a pattern or a tension worth arguing.
Phrasing a claim you can support
The phrasing matters as much as the idea. A good claim is specific, takes a clear position, and hints at the reasoning to come.
- Too broad: "Technology has changed society." (Who could disagree? What would you even prove?)
- Too narrow or factual: "Smartphones were released in 2007." (Undisputed.)
- Defensible: "Smartphones have made us more reachable but less reachable to the people in the room." (Arguable, specific, supportable.)
Why this matters for the exam
The argument essay asks you to make and defend your own claim; an obvious or fence-sitting claim cannot earn the thesis point. The synthesis essay asks you to develop a position from sources. Even the rhetorical analysis essay needs a defensible claim about how the writer's choices work. Every essay begins with this skill.

Q1. State the two-part test for a defensible claim. [Recall]
- Cue. It must be arguable (a reasonable person could disagree) and supportable (you can defend it with evidence and reasoning).
Q2. Turn the topic "homework" into a defensible claim suitable for an argument essay. [Short explanation]
- Cue. For example: "Homework helps students less by teaching content than by training the self-discipline schools rarely teach directly." It takes an arguable position and could be supported with evidence.

AP 2023 (multiple choice, style)1 marksWhich of the following would best serve as a defensible claim for an argumentative essay? (A) Social media was invented in the twenty-first century. (B) Many people use social media every day. (C) Social media has done more to isolate young people than to connect them. (D) This essay will discuss social media. (E) Social media is a form of technology.Show worked answer →
Answer: (C). The skill is recognizing what makes a claim defensible: it must be arguable and require support.
(C) takes a contestable position ("more to isolate than to connect") that reasonable people could dispute and that evidence could defend. That is a defensible claim.
Why not the others: (A) and (E) are verifiable facts no one disputes; (B) is an undisputed generalization; (D) announces a topic but takes no position. None of them can be argued, so none can anchor an essay.
Markers reward distinguishing an arguable position from a fact or a topic statement.
AP 2024 (argument, style)6 marksSome say that progress requires forgetting the past; others say it requires remembering it. Write an essay that argues your own position on the role of memory in progress, supporting a defensible claim with specific evidence and reasoning.Show worked answer →
Free Response Question 3 (argument), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication). The whole essay is built on the defensibility of your claim.
Thesis (1 point): take a clear, arguable position, e.g. "Progress depends on remembering the past precisely so it can be argued with, not preserved." A claim that merely restates the prompt or sits on the fence cannot earn the point.
Evidence and commentary (4 points): support the claim with specific examples (historical movements, literature, science) and explain how each defends the position.
Sophistication (1 point): acknowledge the strongest version of the opposing claim and show why yours still holds.
A vague or obvious claim caps the essay; a defensible one opens it up, which is why developing the claim comes first.
