Revising & Refining Claims (College Board AP® English Language & Composition): Revision Note

This study guide introduces you to how writers test, refine and revise claims in response to evidence. It also shows how changes to a thesis may require changes to the argument’s line of reasoning.

What does it mean to revise and refine a claim?

A thesis is the overarching claim a writer seeks to defend with reasoning and evidence. When you begin an argument, your first thesis is often a working thesis. As you consider possible evidence, you may discover that this thesis is:

• Too broad

• Too absolute

• Missing an important condition or exception

• Supported for a different reason than you expected

• Contradicted by strong evidence

A strong writer responds to that discovery rather than forcing the evidence to fit the original position.

In response to that discovery, you may:

Revise a claim

Sometimes new evidence does more than add a condition or exception. It may challenge an important assumption or the central position itself. In that case, you may need to revise the thesis more substantially and rebuild part of the line of reasoning.

Working claim:

Suppose you then consider evidence showing that, in some collaborative settings, competition can cause individuals to withhold information, protect their own advantage or work against the success of the group. This evidence challenges the original assumption that stronger individual performance necessarily produces a stronger group, which necessitates a revised claim.

Revised claim:

Here, the writer’s position has changed substantially. The argument is no longer “competition is beneficial.” It now distinguishes between situations in which competition may help and situations in which cooperation may be more effective.

Revising a claim will also lead to revising the line of reasoning. In the above examples, the line of reasoning in the working thesis could be:

1. Competition increases motivation

2. Greater motivation improves individual performance

3. Better individual performance strengthens the group

After revising the claim, the revised line of reasoning might be:

1. Competition can motivate individual effort

2. Individual improvement does not always improve group performance

3. Collaborative tasks depend on information-sharing and coordinated effort

4. The value of competition, therefore, depends on the type of goal people are trying to achieve

Refine a claim

To refine a claim is to make it more precise while keeping its central position.

Working claim:

Suppose you then consider examples showing that competition sometimes encourages people to undermine others. 

Refined claim:

Here, the writer has not abandoned the original idea; the claim has become more precise and defensible.

How new or contradictory evidence changes your thesis and line of reasoning

New evidence does not automatically require a new thesis. First, determine what part of the argument the evidence affects:

How to revise a claim in response to new evidence: step-by-step

1. State your working thesis:

   • Identify exactly what you are trying to prove

2. Test the thesis against your evidence:

   • Ask of each example, what does this evidence actually show?

3. Find the pressure point:

   • If the evidence does not fit, identify exactly what it challenges

   • Ask whether the problem is:

     • An absolute word such as "always", "never", "all" or "best"

     • The scope of the claim

     • One supporting reason

     • An unstated assumption

     • The central position

   • For example, evidence showing harmful competition may challenge the assumption that competition is always beneficial, not the idea that competition can sometimes be useful

4. Decide how much revision is necessary:

   • Can you make the original position accurate by narrowing or qualifying it?

   • If yes, then refine the thesis

   • If the evidence challenges the central position more substantially, revise the thesis or line of reasoning

5. Rewrite the claim, if necessary:

   • Decide whether to completely revise or refine

6. Adjust the line of reasoning:

   • Make sure the supporting reasons prove the new version of the claim

7. Check the reasoning chain:

   • For each important example, consider completing the following statements:

     • This evidence supports my reason because...

     • This reason supports my thesis because...

   • If either connection becomes difficult to explain, the argument may still need revision

Worked example: revising a claim

Prompt:

• Develop a position on the extent to which competition benefits individuals or groups

Working thesis:

Test the thesis against the evidence:

Identify the pressure point:

The evidence does not show that competition has no value. Instead, it challenges two assumptions in the working thesis:

1. That competition is generally beneficial

2. That what motivates individuals will necessarily benefit groups

Decide how far the evidence requires the argument to change.

Revised thesis:

Revise the line of reasoning:

What changed?

The writer:

• Kept evidence that genuinely supported the original position

• Acknowledged evidence that complicated it

• Identified the assumptions

• Distinguished individual performance from group success

• Revised the thesis according to the evidence 

• Adjusted the line of reasoning to match

Model paragraph:

Competition can encourage improvement because clear goals give individuals a reason to increase their effort. Athletes competing for positions, for example, may train more consistently because performance has an immediate consequence. Yet greater motivation does not automatically make competition beneficial in every setting. When employees withhold information to gain an advantage or team members prioritize personal success over a shared goal, competition can weaken the group it is supposed to strengthen. The value of competition, therefore, depends not simply on whether people compete, but on whether the structure of the competition encourages both achievement and productive cooperation.

Tips for revising and refining claims

Do not force evidence to fit your claim:

• When evidence complicates your argument, do not:

  • Ignore it

  • Exaggerate what it proves

  • Pretend that it supports a claim

  • Abandon the argument before determining what the evidence actually affects

• When evidence does not fully support a thesis, you may qualify the thesis, use the evidence as a counterexample, reconsider the original position or select stronger evidence rather than force a connection or abandon the development of your idea.

Find the pressure point before you rewrite your thesis:

• If you find contradictory evidence, ask:

  • Exactly what part of my claim does this evidence challenge?

• Revise that point

• The goal is not to defend your first thesis at all costs or abandon it at the first sign of a complication:

  • The goal is to make the claim accurately reflect the evidence

Frequently asked questions

What is the difference between revising and refining a claim?

Refining makes a claim more precise while generally preserving its central position. Revising involves a more substantial change because the original claim or reasoning no longer fits the evidence adequately. 

Should I change my thesis if I find contradictory evidence?

Not automatically. First, you need to determine what the evidence actually contradicts. Finding contradictory evidence may require you to do one or more of the following:

• Add a qualification

• Narrow the claim

• Change one supporting reason

• Acknowledge an exception

• Reconsider an assumption

• Revise the thesis itself

How does revising a claim affect my line of reasoning?

If the thesis changes, ask whether each supporting reason still helps to prove the thesis. Remember that claims, evidence and commentary must contribute logically to the overarching thesis. Therefore, a paragraph may need to be:

• Revised

• Moved

• Qualified

• Removed

• Interpreted differently

How is this tested on the AP Lang exam?

This skill applies broadly to argument writing. Again, remember that the thesis, evidence and line of reasoning should remain aligned. 

In FRQ 1, the synthesis essay, you are provided with sources that may support, extend, qualify or challenge your initial position. Effective synthesis requires you to account for what the evidence actually establishes rather than forcing every source to agree with your first thesis. 

In FRQ 3, the argument essay, you generate evidence from your own knowledge and experience. As you test a working position against that evidence, you may discover that your claim is too broad, absolute or difficult to defend. Refining or revising the position can produce a stronger line of reasoning.
