Synthesis Essay Example (With Breakdown)
A synthesis essay combines multiple sources into a unified argument. Unlike a research essay, which is usually longer and builds a more complete case, a synthesis essay (often assigned in AP English) is tighter and focuses on the move of using the sources together. The three things it has to do are take a position, cite at least three sources in support of a single claim, and show the sources talking to each other rather than just citing them in sequence.

Why the Right to Repair Deserves Federal Legislation
Breakdown
Drawing on sources from consumer advocacy, manufacturer filings, and environmental analysis, this essay argues that federal right-to-repair legislation is overdue...
A synthesis essay should tell the reader in the first paragraph which sources are coming and what claim they will support. This is different from a research essay, which can hold back source identification for longer.
The filing is specific and clearly written, and it deserves serious engagement rather than dismissal.
Synthesis essays fail when they cherry-pick sources. This one gives the manufacturer filing credit, notes its specific argument, and then rebuts it on the merits. The move makes the rebuttal trustworthy.
the closest natural experiment we have, which is the comparison of states that already have partial right-to-repair laws to states that do not.
The second source is not introduced as another opinion — it is introduced as evidence against the first source's claim. Synthesis is strongest when sources are put in direct conversation, not listed in parallel.
Source C (an environmental-impact analysis) estimated that restricted repair policies generated roughly 1.5 million metric tons of additional US electronic waste in 2023 alone...
The third source brings environmental evidence, which neither of the first two covered. A good synthesis selects sources that cover different parts of the argument rather than sources that all make the same point.
No single source makes this entire argument, but together they establish it. That is what synthesis is for — using sources to do work that no individual source could do alone.
The essay explicitly names the synthesis move. This may seem heavy-handed, but in a synthesis essay it is the move the assignment is asking for, and making it visible shows the reader the combined argument.
The question is whether it should be left to state-by-state patchwork or established as a federal baseline.
The conclusion reframes the question more narrowly than the introduction did — now that the evidence is on the table, the remaining question is about level of government. This narrowing is what makes the closing feel earned.
Writing tips
Pick sources that cover different parts of the argument, not sources that all say the same thing. Steelman each source before rebutting or qualifying it. Use explicit transition phrases that put sources in conversation ("contradicts", "extends", "is supported by") rather than listing them in parallel. Close by naming what the combined evidence establishes that no single source could.
