What this rubric measures
The AP Lang Synthesis Essay Rubric (FRQ 1) is the official scoring guide used to evaluate student writing on AP English Language assessments. It is an Analytic rubric that scores responses across 3 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.
All 3 scoring criteria
Click any criterion to expand its score level descriptors. The language below is taken verbatim from the official College Board AP English Language scoring guide.
1 Row A: Thesis
Responds to the prompt with a thesis that presents a defensible position.
- Responds to the prompt rather than restating or rephrasing the prompt, and the thesis clearly takes a position rather than just stating that there are pros and cons.
For any of the following:
- There is no defensible thesis.
- The intended thesis only restates the prompt.
- The intended thesis provides a summary of the issue with no apparent or coherent claim.
- There is a thesis, but it does not respond to the prompt.
- Only restates the prompt.
- Does not take a position, or the position is vague or must be inferred.
- Equivocates or summarizes others' arguments but not the student's (e.g., "some people say it's good, some people say it's bad").
- States an obvious fact rather than making a claim that requires a defense.
The thesis may be more than one sentence, provided the sentences are in close proximity. The thesis may be anywhere within the response. For a thesis to be defensible, the sources must include at least minimal evidence that could be used to support that thesis; however, the student need not cite that evidence to earn the thesis point. The thesis may establish a line of reasoning that structures the essay, but it needn't do so to earn the thesis point. A thesis that meets the criteria can be awarded the point whether or not the rest of the response successfully supports that line of reasoning.
2 Row B: Evidence and Commentary
EVIDENCE: Provides specific evidence from at least three of the provided sources to support all claims in a line of reasoning. AND COMMENTARY: Consistently explains how the evidence supports a line of reasoning.
- Uniformly offer evidence to support claims.
- Focus on the importance of specific words and details from the sources to build an argument.
- Organize and support an argument as a line of reasoning composed of multiple supporting claims, each with adequate evidence that is clearly explained.
EVIDENCE: Provides specific evidence from at least three of the provided sources to support all claims in a line of reasoning. AND COMMENTARY: Explains how some of the evidence supports a line of reasoning.
- Uniformly offer evidence to support claims.
- Focus on the importance of specific words and details from the sources to build an argument.
- Organize an argument as a line of reasoning composed of multiple supporting claims.
- Commentary may fail to integrate some evidence or fail to support a key claim.
EVIDENCE: Provides evidence from or references at least three of the provided sources. AND COMMENTARY: Explains how some of the evidence relates to the student's argument, but no line of reasoning is established, or the line of reasoning is faulty.
- Consist of a mix of specific evidence and broad generalities.
- May contain some simplistic, inaccurate, or repetitive explanations that don't strengthen the argument.
- May make one point well but either do not make multiple supporting claims or do not adequately support more than one claim.
- Do not explain the connections or progression between the student's claims, so a line of reasoning is not clearly established.
EVIDENCE: Provides evidence from or references at least two of the provided sources. AND COMMENTARY: Summarizes the evidence but does not explain how the evidence supports the student's argument.
- Tend to focus on summary or description of sources rather than specific details.
Simply restates thesis (if present), repeats provided information, or references fewer than two of the provided sources.
- Are incoherent or do not address the prompt.
- May be just opinion with no textual references or references that are irrelevant.
Writing that suffers from grammatical and/or mechanical errors that interfere with communication cannot earn the fourth point in this row.
3 Row C: Sophistication
Demonstrates sophistication of thought and/or a complex understanding of the rhetorical situation. Responses that earn this point may demonstrate sophistication of thought and/or a complex understanding of the rhetorical situation by doing any of the following:
- Crafting a nuanced argument by consistently identifying and exploring complexities or tensions across the sources.
- Articulating the implications or limitations of an argument (either the student's argument or arguments conveyed in the sources) by situating it within a broader context.
- Making effective rhetorical choices that consistently strengthen the force and impact of the student's argument.
- Employing a style that is consistently vivid and persuasive.
Does not meet the criteria for one point. Responses that do not earn this point:
- Attempt to contextualize their argument, but such attempts consist predominantly of sweeping generalizations.
- Only hint at or suggest other arguments.
- Use complicated or complex sentences or language that is ineffective because it does not enhance the student's argument.
This point should be awarded only if the sophistication of thought or complex understanding is part of the student's argument, not merely a phrase or reference.
How to score with the AP Lang Synthesis Essay Rubric (FRQ 1).
A practical guide for teachers and norming teams. How to apply each descriptor consistently, the pitfalls that hurt inter-rater reliability, and a workflow for calibrating with colleagues.
Three rows, scored independently
- Score Row A first (binary, 0 or 1), then Row B (0 to 4), then Row C (binary, 0 or 1). Sum for the FRQ total out of 6.
- Row A and Row C are pass/fail style, the response either meets the criteria for the point or it does not. There is no partial credit on these rows.
- Row B is the heaviest-weighted row and the most common source of score variance between graders.
Apply decision rules literally
- For Row A, the thesis must take a defensible position. Restating the prompt, summarizing both sides without a stance, or stating an obvious fact does not earn the point.
- For Row B, count the number of provided sources referenced (2 minimum for 1 point, 3 minimum for 2 to 4 points).
- For Row C, sophistication must be PART of the argument, not just a single sophisticated phrase or sentence.
Common pitfalls to avoid
- Awarding Row B 4 when commentary is strong but evidence is from only 2 sources, minimum 3 sources required.
- Awarding Row B 4 to a response with grammar or mechanics errors that interfere with communication, the rubric explicitly caps such responses at 3.
- Awarding Row C 1 for a sophisticated phrase or quotation that is not integrated with the student's argument.
Tips for AP norming
- Anchor your norming session with the College Board's released sample responses, scored and annotated by AP Readers.
- Score the first 5 student essays silently, then compare. Discuss any row where graders are more than one point apart.
- Re-norm halfway through a long batch. The 6-point scale is sensitive to drift, especially on Row B.
Notes for the AP English Language Synthesis Essay Rubric (FRQ 1)
The synthesis essay specifically requires students to integrate evidence from at least three of the provided sources to reach Row B 2 or higher. Two sources caps Row B at 1, even with strong commentary.
Row B rewards a line of reasoning, not just a sequence of cited sources. Responses that present each source as a separate paragraph without connecting them into a single argument typically score Row B 2 or 3, not 4.
The synthesis prompt provides 6 to 7 sources but expects students to choose at least 3 and use them in service of the student's own position. Responses that try to use all 7 sources superficially typically score lower than focused responses that use 3 sources deeply.
Mechanical and grammatical errors that interfere with communication cap Row B at 3 by explicit rule. A response with strong evidence and commentary but error-laden prose cannot earn the top Row B point.

Why a year of national service would strengthen American democracy
Americans across the political spectrum agree the country feels more divided than at any point in recent memory. A mandatory year of national service for citizens ages 18 to 26 would directly address that division, building a shared civic identity that the United States currently lacks and producing measurable returns for both individual participants and the country.
A shared civic experience the country is missing
Source A documents that fewer than 1 percent of Americans currently serve in the military, down from over 12 percent at the height of WWII. The result is a population that has very little in common across geographic, racial, and economic lines. Source C, a former senator's op-ed, argues that mandatory service would create the first sustained civic experience that all young Americans share since the draft ended in 1973. The senator's claim is that this shared experience, more than any policy lever, is what builds national cohesion. Source A's data and Source C's argument together suggest that the cohesion problem is structural, not cultural, and requires a structural intervention.
Demonstrated returns from civic service programs
Skeptics will say that civic service produces vague benefits at best. Source D pushes back: it summarizes a 10-year longitudinal study of AmeriCorps alumni finding that program completers earned 8 percent higher wages five years out and were 14 percent more likely to be civically engaged (voting, volunteering, attending local meetings) than a matched control group. These are not vague benefits. They are measurable individual and societal returns that justify the program's cost.
Addressing the autonomy concern
The strongest objection comes from Source B, which argues that mandatory service violates personal liberty. This is a serious point in a country built on individual freedom. But the same source acknowledges that the United States already requires civic duties of its citizens: jury service, selective service registration, payment of taxes. A year of national service would extend a principle already accepted, not invent a new one. Source B's concern is real, but it cannot be the final word.
Conclusion
The country has a cohesion problem (Source A), a workable model with measurable returns (Source D), and a tradition of civic obligation (Source B itself concedes this). Mandatory national service would solve a structural problem with a structural solution. It is time to take it seriously.
Defensible position taken in the introduction
The thesis takes a clear, defensible position (that mandatory national service would strengthen democracy) and goes beyond restating the prompt by previewing the line of reasoning. It earns the Row A point.
Four sources integrated; commentary explains the line of reasoning
Four sources (A, B, C, D) integrated with specific evidence (1% military service, 8% wage gain) supporting a single line of reasoning about cohesion. Source B counterargument is acknowledged AND addressed, not just mentioned. Clear Row B 4.
Nuanced argument that situates the position in broader context
Sophistication is built into the argument. The response situates the position in a broader context (existing civic obligations like jury duty) and acknowledges Source B's autonomy concern while still defending the thesis. Earns Row C.
