AP US History LEQ Rubric Explained: How the 6 Points Are Scored

The long essay question, or LEQ, is the last free-response question on the exam. You choose one of three prompts and write for about 40 minutes with no documents, so every piece of evidence comes from your own memory. That is why specific examples matter so much. This guide explains each of the six rubric points in plain language, shows a weak and a strong example from AP US History, and gives you a time plan. The three LEQ choices span Periods 1 to 3, 4 to 6, and 7 to 9, so you always have a prompt from a part of the course you know well.

The six points at a glance

Row	Points	What earns it
Thesis	1	A defensible claim that answers the prompt and sets up a line of reasoning.
Contextualization	1	A broader historical context for the prompt, described in more than a phrase.
Evidence	2	1 point for at least two specific, relevant examples; a second point for using specific evidence to support an argument and explaining how each example supports the claim.
Analysis and reasoning	2	1 point for using comparison, causation, or continuity and change to frame the argument; a second point for a sustained, complex understanding.
Total	6

The LEQ counts for 15 percent of your exam score. Throughout this guide we use one sample prompt: Evaluate the extent to which the Market Revolution changed American society from 1800 to 1848.

First, name the reasoning the prompt wants

Every LEQ asks you to use one of three kinds of historical reasoning. Comparison prompts say "compare" and want similarities and differences. Causation prompts ask about causes or effects, or the relative importance of causes. Continuity and change prompts ask how much something changed, or what stayed the same, over a period of time. The sample prompt above uses continuity and change over time. Spotting the type before you write is the single most useful habit for this essay, because it decides how you organize everything.

Point 1: the thesis

The thesis must answer the prompt, make a claim someone could disagree with, and tell the reader how you will argue it. It can sit in the introduction or the conclusion. It cannot repeat the question or list topics.

Does not earn the pointThe Market Revolution changed American society in many ways, including its economy, its workplaces, and its politics.

It restates the prompt and lists areas. It never weighs how much changed, which is what "evaluate the extent" asks for.

Earns the pointThe Market Revolution transformed how Americans produced, moved, and sold goods far more than it changed who held power: canals, mills, and the cotton boom tied farmers and workers to distant markets, but slavery deepened in the South and political power stayed with white men, so the change was economic and regional rather than a reshaping of all of society.

It answers the extent question, separates what changed from what did not, and previews the categories the body paragraphs will use.

Point 2: contextualization

Context means describing the bigger historical picture around the prompt: developments before it, during it, or after it. It has to be more than a phrase, and it has to be relevant. A few connected sentences in the introduction are usually enough.

Earns the pointIn 1800 most Americans were farmers who grew food for their families and traded locally, and skilled artisans made goods in small shops. The embargo of 1807 and the War of 1812 cut off British imports and pushed investors toward American manufacturing. By the 1840s, railroads and the telegraph were binding the country even more tightly, and the growing economic differences between North and South were sharpening the debate over slavery.

It describes the economy before the time frame and developments after it, and both ends connect to the question of how much society changed.

Points 3 and 4: evidence

The first evidence point needs at least two specific examples relevant to the prompt. The second needs you to use specific evidence to support an argument and explain how each example supports the claim. Because there are no documents, build a short list of examples for each major topic before the exam: a name, a law, a date, a place, and what it did.

Earns both pointsThe Erie Canal, opened in 1825, linked the Great Lakes to the Atlantic through the Hudson River and sharply cut the cost of shipping grain and goods, which turned western farms into suppliers for eastern cities and made New York the nation's leading port. In the same years, the Lowell mills in Massachusetts hired young unmarried farm women, housed them in company boardinghouses, and paid them wages, which shows factory work pulling people out of the household economy. Both examples support the claim that how Americans worked and traded changed deeply.

Each example is specific (a place, a date, a fact), and the last sentence says how the evidence supports the claim. That second step is what the second evidence point asks for.

Points 5 and 6: analysis and reasoning

The first analysis point rewards an essay that uses comparison, causation, or continuity and change to frame its argument. The second rewards a sustained, complex understanding. It is the hardest point on the rubric, so do not plan the whole essay around it.

Reasoning. This prompt uses continuity and change over time. Organize the essay around what changed (production, transportation, labor) and what stayed the same (who could vote, women's legal status, and the South's dependence on enslaved labor). One paragraph on each side is stronger than a list of changes.

Complexity. Show that the change was uneven. The North industrialized, while the South expanded cotton and slavery after the cotton gin made short-staple cotton profitable, and Native nations in the Southeast were removed from land that cotton planters wanted. Tracing how one development produced very different results in different regions, and keeping that thread through the whole essay, is what earns complexity.

A 40-minute time plan

Minutes	What to do
0 to 5 min	Read all three prompts. Choose the one where you can name the most specific examples, not the one with the most familiar topic. Circle the command words and the time frame, and jot four to six pieces of evidence.
5 to 10 min	Write the introduction: a few sentences of context, then a thesis that makes a claim and previews your categories.
10 to 30 min	Write two body paragraphs. Each makes one claim, gives at least two specific examples, and explains how each example supports the claim.
30 to 37 min	Write a third body paragraph that qualifies or complicates your argument. This is where complexity usually comes from.
37 to 40 min	Add a short conclusion that sharpens the thesis. Check that every body paragraph still answers the prompt.

Common mistakes

Writing a list of changes with no judgment. "Evaluate the extent" means you must weigh how much changed and what did not.
Drifting outside the time frame. A prompt that ends in 1848 will not reward a paragraph on the Civil War.
Naming examples without details. "The Erie Canal" alone is a name, not evidence. Add the date, the place, and the effect.

Frequently asked questions

How many points is the AP LEQ worth?

The AP US History long essay is scored out of 6 points. It counts for 15 percent of your total exam score.

How many examples do I need?

At least two specific examples for the first evidence point. For the second, you need evidence that supports an argument and an explanation of how each example supports it. Aim for four to six specific examples across the essay.

How is the LEQ different from the DBQ?

The LEQ has no documents. All of your evidence comes from your own knowledge, so you must remember specific people, laws, events, dates, and places. You also choose one of three prompts.

Does my thesis have to be in the introduction?

No. The rubric accepts a thesis in the introduction or the conclusion. Most strong essays put it first so that the body paragraphs have a direction.

What if I do not remember exact dates?

The time frame matters for staying on topic, but a specific, accurate description of an event, law, or policy counts as evidence even without a date. Do not guess a date you are unsure of.
