HISTORICAL THINKING · SOURCING
AP U.S. History: how do you analyze an author’s purpose and context?
Connect an author’s identity, audience, purpose and historical situation to specific evidence. Decide what a source can and cannot establish, then try an original sourcing question.

A note from your study buddyAfter identifying who wrote a source, ask why that matters for what the author says and how they say it.
01 / DIRECT ANSWER
Move from who wrote it to why that matters
Sourcing connects the author’s or organization’s identity, intended audience, purpose and historical situation to specific language in a source. Explain why those features affect the source’s perspective, usefulness or limitations.
Calling a source biased is not enough. A more useful explanation identifies whom the author wants to persuade, what action they want and which problems they emphasize as a result. Then consider what the source can support and whose views it cannot establish.
For an MCQ, choose the inference the evidence best supports. SAQs and DBQs have their own tasks and scoring requirements. This is a reading method; a particular response must still follow the prompt and current official rubric.
02 / SOURCE WALKTHROUGH
What can an advocacy program tell us?
Consider the National Organization for Women’s (NOW) 1966 Statement of Purpose. Here is an AP Exam Kit summary for this lesson:
NOW advocated fuller participation by women in employment and public institutions. It criticized inadequate federal enforcement of protections already in law and argued that a few symbolic appointments could not replace sustained reform.
NOW, Statement of Purpose, 1966 · AP Exam Kit summary, not a verbatim quotation
| Angle | Evidence | An explanation it supports |
|---|---|---|
| Author / organization | NOW, a newly formed advocacy organization | The program directly records the reforms that organization wanted to promote. |
| Purpose | Calls for action and fuller participation | Emphasizing weak enforcement helps explain why organized action is still needed. |
| Audience | A public organizational program | It can address potential supporters and the public. Public circulation alone does not establish each reader’s response. |
| Historical situation | Criticizes enforcement after the Civil Rights Act of 1964 | The gap between legal protections and implementation helps explain its demands. |
Sample explanation: Because the statement invokes existing employment protections while asking for more effective implementation, it helps reveal the organization’s reform demands. To establish how much enforcement actually improved, a historian would also need evidence such as enforcement records.
Keep separate what the source explicitly states and what you can reasonably infer from it. Label any inference that extends beyond its evidence rather than presenting it as an established fact.
03 / COMMON MISTAKES
A list of source features still needs an explanation
Calling the author a reformer is a start. Explain how that role shapes the issues emphasized or the action requested.
Programs, speeches and diaries each have a scope. Broader public opinion usually requires additional evidence from different sources.
A call for better policy establishes a demand. By itself, it does not establish that policy changed or that every reader accepted the argument.
04 / YOUR TURN
Use identity and purpose to assess a claim
The prompt and options come from the original question bank. Feedback appears in English after submission. This is an AP Exam Kit original question, not an official College Board question.
ORIGINAL MCQ · NO ACCOUNT NEEDED
Brief excerpt: “bring women into full participation in the mainstream of American society now”. Adaptation: NOW called for meaningful participation in employment and public institutions. Its statement criticized the federal employment commission’s inadequate enforcement of protections already written into federal law and rejected token appointments as sufficient progress.

Keep asking what evidence you would need
The next original question uses the same source to examine what evidence or response would address its claims. The practice workspace also lets you explore other units and question types.
