Grading AP Language Synthesis Essays That Use The 9/11 Report as a Source

Published on October 9th, 2026 by the GraideMind team

Synthesis essays require students to combine several sources into an argument of their own, and a graphic adaptation like Sid Jacobson's The 9/11 Report can be an interesting source for practice. Teachers in AP Language and AP Government can include excerpts alongside articles, speeches, or data. The result is a task that tests reading, argument, and source integration. Grading it requires attention to how students use sources, not just whether they mention them.

A common weakness in synthesis writing is the source dump, where students summarize each source in turn with little connection among them. True synthesis puts sources in conversation, using one to qualify or extend another. A student might use the adaptation to illustrate a point, then bring in another source to challenge it. Teach this move explicitly, because it does not happen naturally.

Another challenge is that students need to treat the graphic adaptation as a source with its own perspective. They should consider who created it, for what audience, and how format shapes message. Including a sourcing step in the prompt prompts more thoughtful engagement. It also aligns with the skills assessed on the exam.

Scoring the Essential Skills

A synthesis rubric typically examines the thesis, the use of evidence from multiple sources, the commentary that explains the evidence, and the sophistication of the argument. Each element should be defined with clear descriptors. A high-scoring essay uses at least several sources purposefully and builds a line of reasoning that the sources help advance. Students should be reminded that the argument comes first and the sources serve it.

  • Presents a defensible thesis that responds directly to the prompt
  • Incorporates multiple sources, including the graphic adaptation, in service of the argument
  • Explains how each piece of evidence supports the line of reasoning
  • Places sources in conversation rather than summarizing them separately
  • Demonstrates sophistication by acknowledging complexity or tension

Synthesis happens when sources work together to build an argument the student owns.

Evaluating Commentary

Commentary is the heart of a strong synthesis essay and the area where scores are most often lost. Students must explain how a source's content supports their claim, not simply quote or paraphrase it. Look for sentences that begin to interpret, such as explaining what a detail reveals about institutional behavior. Distinguish between commentary that adds meaning and commentary that merely repeats the evidence.

A helpful tool is a commentary ladder that shows increasing levels of explanation. At the lowest level, the student restates the source. At the next, they connect it to the claim, and at the highest, they explain why the connection matters in a broader context. Using this ladder in feedback gives students a concrete path to improvement.

Rewarding Sophistication Without Overreaching

Sophistication does not mean fancy vocabulary; it means recognizing nuance. A student who notes that sources emphasize different causes and then explains why shows deeper thinking. Another path is addressing counterarguments or limitations. Be careful to reward genuine insight rather than decorative complexity.

Many students struggle here, so provide examples of sophisticated moves in class. Show how a writer can qualify a claim or consider an alternative explanation. Practice rewriting a plain paragraph into a more nuanced one. These exercises make the abstract concept accessible.

Making Practice Sustainable

Frequent practice improves synthesis skills, but grading full essays is heavy. Alternate between full essays and shorter tasks, such as writing only the thesis and one body paragraph. Focused tasks give targeted practice while reducing workload. They also let you give detailed feedback on specific skills.

Rubric-based tools can help provide timely feedback on structure and evidence use, allowing you to concentrate on commentary and sophistication. Always check the results against your own reading. The combination of speed and judgment gives students more opportunities to practice and improve. That frequency is often what makes the difference by exam day.
