Many AP Government students reach for John Locke when writing about the Declaration of Independence, limited government, or the social contract. Sometimes they use him well, and sometimes his name is dropped in like a password that should earn credit on its own. Teachers need a way to tell the difference quickly, especially when grading dozens of argument essays in a single sitting. The following approach keeps scoring tied to the reasoning students actually show.

The argument essay format rewards a defensible claim supported by evidence and reasoning, and Locke can serve as either. A student might argue that the Declaration reflects Enlightenment thought by pointing to its claim that governments derive their power from the consent of the governed. That is a legitimate use of Locke, but only if the student explains the link and does not simply assert that the ideas are similar. Scorers should look for the explanation, not the name.

It also matters which sources the course actually requires. Locke is not itself a required foundational document, so students who use him are drawing on outside knowledge, and that knowledge needs to be accurate. Misattributing ideas to Locke is a common problem, such as crediting him with separation of powers as later described in the Constitution. Accurate, specific references should earn more credit than vague appeals to the Enlightenment.

Scoring Evidence and Reasoning Separately

A strong essay names a specific idea from Locke, such as natural rights or the right to resist a government that violates its trust. It then connects that idea to a concrete feature of an American document or institution. For example, a student could argue that the Declaration's list of grievances against the king mirrors Locke's account of when people may dissolve a government. The reasoning, not the reference, is what turns a name into evidence.

• Does the student state a defensible claim that responds to the prompt directly?
• Is the Locke reference specific, accurate, and tied to a named idea?
• Does the reasoning explain how the idea connects to the document or institution discussed?
• Does the essay address an opposing view, such as a different influence on the founders?
• Is the language precise enough that a reader could follow the logic without extra context?

Common Errors in Student Essays

One frequent mistake is treating Locke as the sole source of American political ideas. Students forget that the founders drew on classical republicanism, English common law, and colonial experience as well, and a claim that Locke alone explains the Constitution is easy to challenge. Another error is confusing Locke with Montesquieu on separation of powers. Comments that ask students to name the source of a specific institutional feature teach them to be more careful.

Some students also misread the phrase about life, liberty, and property as identical to the Declaration's language. The Declaration substitutes the pursuit of happiness for property, and that difference can support a thoughtful argument about how the founders adapted Locke. Students who notice this shift usually show stronger analysis than those who treat the two lists as interchangeable. A brief comment can point out this opportunity if the student has missed it.

Giving Feedback Students Can Use Before the Exam

Timing matters in test preparation, because students have only a few practice opportunities before the exam. Feedback that arrives two weeks late is nearly useless, while comments returned within a couple of days let them revise while the ideas are still fresh. Keeping comments focused on the claim, the evidence, and the reasoning also mirrors how scorers will read their responses in May. That alignment makes practice more valuable.

Some teachers use a rubric-driven tool like GraideMind to give first-pass feedback quickly on practice essays, then add their own notes on the strongest and weakest papers. This division of labor lets you reach every student without spending entire weekends grading. Whatever process you choose, make sure students see the scoring criteria before they write, since knowing what earns credit changes how they plan. A shared standard also reduces disputes about grades.

Building Locke Into Your Practice Sequence

Instead of assigning a single big Locke essay, spread the skill across several short practice tasks. Early tasks might ask students to write only a claim and one paragraph of reasoning, while later tasks add opposing views and full structure. This gradual approach lets you spot problems with Locke content early, before habits set in. It also produces a smaller stack of grading each time.

By spring, students should be able to introduce outside knowledge like Locke accurately, briefly, and in service of an argument. That is the standard worth scoring against. If your rubric keeps rewarding precision and explanation over name recognition, students will learn that political ideas are tools for reasoning and not decorations.
