## AP English Language and Composition Syllabus

For the AP English Language and Composition, you are expected to understand how body paragraphs develop an argument, with a focus on the following syllabus points:

- Know that a strong body paragraph makes a claim, supports it with evidence, and explains how that evidence supports the line of reasoning
- Identify the difference between a defensible thesis for the whole essay and a paragraph-level supporting claim
- Explain the difference between evidence and commentary
- Understand how specific evidence supports Row B of the AP rubric more effectively than general evidence
- Recognise that quotation or source material must be integrated, not dropped into the paragraph without explanation
- Understand how commentary explains why evidence matters to the argument, audience, or purpose
- Distinguish a supported claim from a paragraph that only lists examples or summarizes material

## Introduction

A large share of AP English Language writing success comes down to one skill: writing paragraphs that do more than make a point. A strong paragraph must make a **supported claim**. That means the paragraph does not stop after stating an opinion or adding a quotation. It proves a point through carefully chosen evidence and then explains how that evidence advances the essay’s argument.

This matters across the course. In argument, you must support your own position. In synthesis, you must support your claim with sources. In rhetorical analysis, you must support your interpretation of the writer’s choices. The task changes, but the paragraph logic stays the same: **claim -> evidence -> commentary -> connection to the line of reasoning**.

> **Key Term: supported claim**
> A claim that is backed by specific evidence and followed by explanation showing how that evidence proves the point.

## Teaching Sections

### What a supported claim actually is

Students often hear “make a claim and support it,” but many still confuse several different levels of argument.

> **Key Term: thesis**
> The essay’s main defensible position or overall argument in response to the prompt.
>
> **Key Term: claim**
> A paragraph-level point or subclaim that supports, narrows, or develops the thesis.

A **thesis** belongs to the whole essay. A **claim** belongs to one paragraph. If your thesis is the roof, each paragraph claim is one supporting beam. A body paragraph should not repeat the thesis word-for-word. It should take one piece of the thesis and develop it.

For example, imagine an argument prompt about whether fear can be useful. A weak thesis might say: “Fear is important.” That is broad. A stronger thesis might say: “Fear can be useful because it warns people of danger, pushes them to prepare, and exposes what they value.” Each reason could become one body paragraph claim.

That gives you paragraph claims such as:

- Fear can function as an early warning system that protects people from immediate harm.
- Fear can motivate preparation when a person responds with discipline rather than panic.
- Fear reveals priorities because people often fear losing what matters most to them.

Notice what each one does. It is not just a topic like “fear and danger.” It is an arguable statement. Someone could challenge it. That is what AP readers want: not a category, but a point.

A weak topic sentence often sounds like this:

- Fear is seen in many situations.
- There are many examples of fear in history.
- Fear can affect people differently.

These are too broad to guide reasoning. They do not tell the reader what the paragraph will prove. They invite summary.

A stronger paragraph claim does three things:

1. It is **arguable**
2. It is **specific**
3. It clearly connects to the thesis
   > **Key Term: topic sentence**
   > The sentence that introduces a paragraph’s main claim and guides the evidence and commentary that follow.

A common student mistake is writing a topic sentence that merely names the subject. For AP Lang, the topic sentence should usually contain the paragraph’s actual claim.

For instance, compare these:

- Weak: Social media affects teenagers.
- Stronger: Social media can widen teenage insecurity because it turns private comparison into a constant public habit.

The second sentence gives direction. It tells the writer what kind of evidence to choose and what commentary to produce. The first one could lead anywhere.

> **Test Tip:** If your topic sentence could fit almost any paragraph on the subject, it is probably too vague. Add a reason, condition, or consequence.

### Evidence: what counts, and what makes it strong

Evidence is broader than many students think. It is not only quotations from books or sources.

> **Key Term: evidence**
> Specific support used to prove a claim, such as facts, data, examples, quotations, observations, or references.

On AP English Language and Composition, evidence may include:

- historical examples
- current events
- literature or nonfiction references
- personal observation or experience
- source material in synthesis
- details from the passage in rhetorical analysis
- data or statistics
- expert opinion

The key is not the category. The key is whether the evidence is **specific, relevant, and usable**.

Consider this paragraph claim:

“School uniforms do little to improve learning because they address appearance rather than the real causes of distraction.”

Now compare weak and strong evidence.

Weak evidence:

- Students get distracted for lots of reasons.
- Some schools have problems even with uniforms.
- People still misbehave.

This is general. Nothing here gives the reader a concrete point to work with.

Stronger evidence:

- A school may require uniforms, yet students can still be distracted by overcrowded classrooms, phone use, sleep deprivation, or weak lesson design.
- If a student is exhausted from working late or caring for siblings, changing clothing does not change readiness to learn.
- Schools with strict dress codes still report behaviour and achievement gaps, which suggests clothing rules do not solve deeper academic problems.

These examples are more specific because they point to actual causes and make the paragraph’s logic clearer.

In synthesis, evidence must come from the provided sources. But even there, not all source use is equal. A vague use of a source might say:

- Source B shows that technology has benefits.

That is barely evidence. It is a summary label. Better source use would identify the actual information:

- Source B reports that technology can improve learning when it is used to personalise pace and support strong teaching.

Now the writer has something to explain.

In rhetorical analysis, evidence should point to particular choices in the text, not just name a device. For example:

- Weak: The writer uses repetition.
- Stronger: The writer repeats “we must” at the start of successive clauses, creating urgency and framing action as a shared duty.

The second version gives text-based evidence and begins to hint at commentary.

Students also need to judge quality. A class survey of 30 students may count as evidence, but it has limits. A single anecdote may be vivid, but it does not prove a universal claim by itself. A quotation from a famous person may sound impressive, but if that person lacks real authority on the issue, the evidence is weaker than it looks.

That is why AP rewards evidence that is not only present, but chosen well.

> **Key Term: source integration**
> The smooth incorporation of quotations, paraphrases, or references into a sentence so that they support the writer’s claim clearly.

A frequent weakness is **quote dropping**:

“Education technology has enormous promise.” This proves that technology is good.

That feels abrupt and thin. A better version introduces and frames the quotation:

A report on education technology argues that personalised digital tools show “enormous promise,” suggesting that technology is most effective when it adapts instruction rather than merely adding screens.

Now the evidence is embedded into the sentence and shaped to serve the claim.

> **Test Tip:** Before using evidence, ask: “What exact point will this prove?” If you cannot answer that in one sentence, the evidence is probably too broad or poorly chosen.

### Commentary: the part that earns points

Many students stop too soon. They write a claim, add an example, and move on. That usually leads to summary, not argument.

> **Key Term: commentary**
> The writer’s explanation of how and why the evidence supports the claim and advances the overall argument.

Commentary is where you do the thinking on the page. Evidence says **what**. Commentary explains **so what** and **how**.

Look at this example:

Claim: Fear can motivate preparation when people channel it into action.

Evidence: Before a major storm, families often buy supplies, charge phones, and review evacuation plans.

Without commentary, this remains obvious but underdeveloped. Add explanation:

Because fear alerts people to genuine risk, it can interrupt passivity and force practical decisions. The emotion itself does not solve the problem, but it pushes people to act before the danger arrives. In that sense, fear becomes useful not because it feels good, but because it converts uncertainty into preparation.

That is commentary. It interprets the example and connects it back to the claim.

A good test is this: if you remove the commentary and the paragraph still sounds complete to you, you may be treating evidence as self-explanatory. On AP, it is usually not.

Here is a side-by-side contrast:

Weak paragraph move:

- This shows fear is useful.

Stronger commentary:

- This example suggests that fear is productive when it sharpens attention toward immediate action. Rather than paralysing people, it can create a deadline that forces planning.

The second version explains the mechanism. It does not just announce a result.

Commentary also helps build complexity. It can qualify claims:

- This does not mean fear is always helpful; when it becomes panic, judgment can collapse.
- The same emotion that protects one person may overwhelm another if there is no clear path to action.

That kind of explanation strengthens reasoning because it shows control over the limits of the claim.

In rhetorical analysis, commentary must explain the effect on the audience and purpose. For example:

Evidence: The speaker begins with “Friends and Fellow Citizens.”

Commentary: By greeting the audience in civic rather than private terms, the speaker creates shared identity and frames the issue as public and constitutional, not merely personal.

In synthesis, commentary must explain how the source supports your position, not merely what the source says. For example:

Evidence: Source C argues that early screen exposure may affect development.

Commentary: This supports the claim that technology should be introduced with caution, especially for younger children whose learning depends heavily on direct human and physical interaction.

Commentary is also where you avoid feature-spotting. Naming a device or inserting a quote is not enough. The paragraph must show reasoning.

### Building a line of reasoning inside and across paragraphs

A strong paragraph does not function alone. It contributes to a larger structure.

> **Key Term: line of reasoning**
> The logical sequence that connects thesis, paragraph claims, evidence, and commentary across an essay.

The College Board values essays that do not feel like piles of examples. A line of reasoning means each paragraph has a job. It advances the argument in an ordered way.

A practical paragraph formula is:

- claim
- evidence
- commentary
- connection or transition

This is not a rigid script, but it is a reliable model.

Here is an original model paragraph for an argument essay:

Claim: Fear can be useful because it exposes what a person truly values.  
Evidence: People rarely feel intense fear about losing what means nothing to them; they fear for family, safety, identity, reputation, or future goals. A student may feel terrified before a scholarship interview not because interviews are inherently dangerous, but because the opportunity matters deeply.  
Commentary: In that way, fear acts like a diagnostic tool. It reveals attachment and priority. The emotion is unpleasant, but it clarifies what is at stake, which can then guide action. The student who recognises that fear as evidence of commitment may prepare harder rather than retreat.  
Connection: Thus, fear does more than threaten comfort; it can define value, supporting the larger claim that discomfort is not always an enemy.

Notice the movement. The paragraph begins with a claim, uses a concrete example, explains the logic, and reconnects to the thesis.

Students often break the line of reasoning in a few common ways:

1. **Listing without connecting**  
   They pile up examples: history, literature, personal experience. But the paragraph never explains the relation among them.

2. **Repeating the claim**  
   They restate the idea in slightly different words instead of deepening it.

3. **Changing the subject mid-paragraph**  
   They begin with one claim, then chase a loosely related point because the evidence does not match the topic sentence.

4. **Ending without linkage**  
   The paragraph finishes after the evidence, so the reader must guess why it mattered.

To avoid this, your paragraph claim should control your choices. If the evidence does not help prove that exact claim, either replace the evidence or revise the claim.

Transitions matter too, but not just fancy words. A real transition shows relationship:

- This example strengthens the earlier point that...
- If fear can protect in moments of danger, it can also motivate preparation before danger arrives.
- While the previous paragraph shows fear’s protective function, this one shows its interpretive function.

These transitions maintain the line of reasoning across the essay.

> **Key Term: transition**
> A word, phrase, or sentence that shows the logical relationship between ideas or paragraphs.

### Common mistakes and how to fix them

The fastest way to improve paragraph writing is to spot typical weak patterns.

Mistake 1: Claim + evidence only  
Students think a quote finishes the job.

Fix: After each piece of evidence, add 2-4 sentences answering:

- What does this show?
- Why does it matter?
- How does it support the claim?

Mistake 2: Vague evidence  
Students use phrases like “throughout history” or “many people.”

Fix: Replace broad phrases with one precise example, event, source detail, or observation.

Mistake 3: Summary instead of explanation  
Students retell what happened in a book, source, or passage.

Fix: Move from “what happened” to “what that proves.”

Mistake 4: Paragraph claim too broad  
Students begin with a sentence so general that the paragraph loses focus.

Fix: Add a reason, condition, or consequence to the topic sentence.

Mistake 5: Thesis and claim confused  
Students repeat the thesis in every paragraph.

Fix: Let each paragraph handle one slice of the thesis.

Mistake 6: Quote dropping  
Students insert a quotation with no framing or analysis.

Fix: Add a signal phrase and follow with commentary.

Here is a quick repair example.

Weak:
Social media affects self-image. Many teens compare themselves online. This happens a lot today.

Improved:
Social media can intensify self-image anxiety because it turns comparison into a public, repeated habit. A teenager scrolling through edited images and popularity metrics is not simply observing others; that student is receiving constant signals about status, beauty, and approval. Because those signals are visible and frequent, they can reshape how value is measured. The issue, then, is not mere phone use but the way public comparison becomes built into everyday experience.

The improved version gives a sharper claim and meaningful commentary.

> **Test Tip:** If you finish a paragraph and most of the sentences could be labelled “evidence,” you probably need more commentary. If most could be labelled “commentary,” you may need a clearer example.
