What this topic is asking
Topic 7.6 (skill CLE-1.K) lays the foundation for the synthesis essay, Free Response Question 1. It asks you to understand the task, develop your own defensible position, and support it by putting at least three of the provided sources in conversation. The synthesis essay is an argument essay with sources supplied, and the single skill that decides the score is whether you synthesize the sources, weaving them into your reasoning, or merely summarize them one by one.
What the synthesis essay asks
The prompt always names a minimum number of sources to use (usually three). The sources offer evidence and perspectives on more than one side; your job is to build a position and use them to argue it.
Synthesis versus summary
This is the crux. Summary reports what each source says, one paragraph per source, with little argument of your own. Synthesis uses the sources inside your own line of reasoning: one source supports a claim, another qualifies it, a third answers an objection. The sources are in conversation with each other and with you.
The shared rubric and the reading period
The synthesis essay uses the same 6-point rubric: a defensible thesis (1), evidence and commentary (4), and sophistication (1). The exam gives a 15-minute reading period before you may write; use it to read each source for its position and perspective, mark usable evidence, decide your own position, and plan which sources go where, rather than reading passively.
Why this matters for the exam
The synthesis essay is one of three free-response questions, together 55 percent of the score. It draws together almost every skill in the course: taking a position, weighing perspective and credibility, putting arguments in conversation, qualifying claims, and reaching sophistication by holding genuine tension. Because it supplies the evidence, it most directly tests whether you can integrate sources into an argument, the defining academic skill the course teaches.

Q1. What is the difference between synthesizing and summarizing sources? [Recall]
- Cue. Summarizing reports what each source says, usually one source per paragraph, with little argument; synthesizing uses the sources inside your own line of reasoning, putting them in conversation (one supporting, another qualifying) so your argument leads and the sources serve it.
Q2. A student's synthesis essay has three body paragraphs: one on Source A, one on Source B, one on Source C, each summarizing the source. Diagnose the problem and say how to fix it. [Short explanation]
- Cue. The essay is a source-by-source walk-through, summary, not synthesis, so even with three sources it cannot reach the upper band. The fix is to lead with the student's own line of reasoning and reorganize paragraphs around claims rather than sources, drawing on more than one source per paragraph (for instance using Source B to qualify a point made with Source A) so the sources are in conversation and serve the argument rather than structuring it.

AP 2024 (multiple choice, style)1 marksOn the AP Lang synthesis essay, a high-scoring response uses the sources to (A) summarize each one in turn (B) support and develop the student's own argument, in conversation with one another (C) replace the student's position (D) prove a single source correct (E) avoid taking a position.Show worked answer →
Answer: (B). The skill is knowing what synthesis requires.
Synthesis means using the sources to support and develop your own position, putting them in conversation, not summarizing each or letting them substitute for your argument.
Why not the others: (A) summarizing is the classic synthesis failure; (C) and (E) you must take and own a position; (D) the task is not to vindicate one source.
Markers reward sources woven into the student's own line of reasoning.
AP 2023 (synthesis, style)6 marksThe sources below address whether public libraries should remain free to use. Read them carefully. Then write an essay that develops your position, using at least three of the sources in conversation with one another and with your own argument.Show worked answer →
Free Response Question 1 (synthesis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication).
A standard synthesis prompt: take a position and use at least three sources.
Thesis (1 point): take a defensible position on free libraries.
Evidence and commentary (4 points): integrate at least three sources, putting them in conversation (one qualifying another) within your own reasoning, with commentary explaining each.
Sophistication (1 point): weigh sources by perspective and credibility, and hold genuine tension.
The essay rewards synthesis, sources in conversation, over summary.
