What this assignment is really asking
No provided documents — all evidence must come from your own knowledge of the course content. This makes the LEQ more dependent on what you have studied and can recall under exam conditions.
The prompt names one historical reasoning skill: causation (why something happened or what it caused), comparison (how two developments, societies, or time periods are similar or different), or continuity and change over time (what changed and what stayed the same across a period).
A defensible thesis is required — it must make a historically defensible claim with a line of reasoning, not merely restate or rephrase the prompt.
Contextualization earns a separate rubric point — it requires a developed description of a broader historical context that connects explicitly to your argument, not a one-sentence mention.
The rubric distinguishes between naming a specific historical example and actually explaining how that example supports your argument. The higher evidence point requires the explanation.
First move
Name the historical reasoning skill first.
Before brainstorming facts, decide whether the prompt asks for causation, comparison, or continuity and change over time. That skill determines how your evidence should be organized.
- Circle the command phrase and time period.
- Label the prompt as causation, comparison, or continuity/change.
- List four specific historical examples that fit that skill.
What counts as evidence
LEQ evidence comes from your own course knowledge. Strong evidence is specific, named, and explained through the historical reasoning skill in the prompt.
Use this
- Named events, people, policies, movements, dates, or developments from the course.
- Contextualization that connects a broader historical process to the prompt.
- Evidence explained through causation, comparison, or continuity and change over time.
Avoid this
- Vague period statements such as "many changes happened."
- Listing facts without explaining how they support the thesis.
- Using a timeline structure when the prompt asks for comparison or causation.
Follow the exact AP or classroom rubric for thesis, contextualization, evidence, analysis, and complexity thresholds.
How to read a prompt like this
Evaluate the extent to which industrialization changed social life in Europe from 1750 to 1900.
Task verb
Evaluate the extent
You need a judgment about how much changed, not just a description of change.
Topic
industrialization changed social life
Focus on social effects such as class, family, labor, cities, or gender roles.
Reasoning skill
changed
This points toward continuity and change over time.
Time frame
1750 to 1900
Evidence should fit the assigned period and avoid drifting outside it.
First action: Make two columns: what changed and what continued. Put specific historical examples under each.

Paste your exact promptHow to structure it
- 1
Identify the reasoning skill
Read the prompt for causation, comparison, or continuity and change over time. That skill shapes the thesis and the body paragraph structure, so identify it before you brainstorm evidence.
- 2
Brainstorm specific evidence
Spend three to five minutes listing relevant events, people, policies, movements, and developments from the period. Mark the four to six strongest examples, especially the ones you can explain rather than just name.
- 3
Write the thesis
Make a defensible historical claim with a line of reasoning. For causation, name the cause and effect. For comparison, name categories of similarity or difference. For continuity and change, name what shifted, what persisted, and the time frame.
- 4
Plan contextualization
Treat contextualization as its own paragraph or set of sentences. Describe a broader historical development and explicitly connect it to the argument you are about to make.
- 5
Organize by the skill
Build body paragraphs around the reasoning skill, not around a timeline. Each paragraph should state a claim, cite a specific historical example, and explain how that example demonstrates the skill in action.
- 6
Work in complexity
Do not save complexity for a rushed final sentence. Address counterevidence, a different scale or time period, or a nuance that complicates the main claim within the body of the essay.
See the difference
A stronger LEQ thesis names a historical relationship and explains the mechanism. It does not simply list a topic.
Weak
There were many causes of the Civil War.
This restates a broad topic and gives no line of reasoning.
Stronger
The expansion of slavery was the central cause of the Civil War because it turned every new western territory into a national political crisis.
This takes a defensible position and previews how the essay will use evidence.
What teachers look for
Back to topThe thesis must include a line of reasoning, not just a position. "The causes of World War I were primarily political" is insufficient. "The causes of World War I were primarily political because the alliance system transformed a regional crisis into a continental war" earns the thesis point — it states a position and explains the mechanism.
Contextualization requires a developed, connected discussion — not a one-sentence mention. A full paragraph describing the broader historical context and explicitly connecting it to the argument you are about to make is what earns the rubric point.
Name specific evidence, then explain it. "The Emancipation Proclamation" is not yet evidence — "The Emancipation Proclamation of 1863 shifted the war's moral framing in ways that discouraged European recognition of the Confederacy" is evidence with analysis.
Organize paragraphs around your reasoning skill, not around a timeline. For causation, each paragraph discusses a distinct cause. For comparison, each paragraph compares across the same category. For continuity and change, separate what changed from what continued.
Common mistakes to avoid
Back to topWriting a thesis that restates the prompt.
Looks like
"There were many causes of the Civil War" takes no position and gives no line of reasoning.
Fix
Make a historically defensible claim and name the logic that will prove it.
Treating contextualization as a one-sentence mention.
Looks like
"Before this period, Europe had been undergoing industrialization" appears without development or connection.
Fix
Describe a broader historical process and explicitly connect it to your argument.
Listing evidence without explanation.
Looks like
The paragraph names events but never says how they prove the thesis.
Fix
After each example, explain how it demonstrates causation, comparison, or continuity/change.
Confusing the reasoning skills.
Looks like
A comparison prompt becomes two separate descriptions, or a causation prompt becomes a timeline.
Fix
Organize the essay around the named skill and make each paragraph perform that skill.
Saving complexity for the conclusion.
Looks like
The final sentence adds a vague caveat after the argument is already over.
Fix
Build nuance into the body through counterevidence, scale, time period, or qualified claims.
Key terms
Back to top- Defensible thesis
- A thesis that takes a historically defensible position that a historian could plausibly disagree with — not merely a restatement of the prompt or a statement of fact. The College Board rubric requires it to include a line of reasoning.
- Line of reasoning
- The logical chain connecting the thesis to the evidence — the explanation of how or why the position is supported. A strong thesis states both a position and a line of reasoning in the same sentence or two.
- Contextualization
- A rubric point earned by describing a broader historical development — before, during, or after the period in the prompt — and explicitly connecting it to the argument. A passing mention does not earn the point; the contextualization must be developed and connected.
- Causation
- A historical reasoning skill that identifies the causes of a historical development, its effects, or both. A causation LEQ requires analyzing why something happened or what it produced — not merely describing what occurred.
- Comparison
- A historical reasoning skill that identifies meaningful similarities and differences between two or more historical developments, societies, time periods, or geographic areas. Comparison requires explaining what the similarity or difference reveals.
- Continuity and change over time (CCOT)
- A historical reasoning skill that analyzes what changed and what stayed the same across a specified time period. A CCOT LEQ requires identifying both changes and continuities and explaining the forces that drove them.
- Complexity
- An optional rubric point earned by demonstrating a nuanced understanding — through corroboration, qualification, tension, application to a different time scale or geography, or by addressing the limits of the main argument.
- Specific evidence
- Named, concrete historical examples — events, people, policies, movements, or developments — that are explained and connected to the argument, as opposed to vague or general statements about a period.
Frequently asked questions
Back to topHow is the LEQ different from the DBQ?
Both are AP History essays that require a defensible thesis, contextualization, evidence, and historical reasoning. The key difference is the source of your evidence. The DBQ gives you 7 primary source documents to analyze and source (HAPP), and requires drawing evidence from those documents alongside outside knowledge. The LEQ gives you no documents — all evidence must come from your own historical knowledge. This makes the LEQ more dependent on what you have studied and can recall.
For a comparison LEQ, do I have to address both similarities and differences?
The prompt will usually direct you — "compare" can mean similarities, differences, or both; "evaluate the extent to which they were similar" focuses on degree of similarity. A strong comparison LEQ organizes body paragraphs by category (e.g., political structures, economic systems, social hierarchies) rather than by subject, and explains what each similarity or difference reveals rather than just listing facts about each side.
What exactly counts as contextualization?
Contextualization requires describing a broader historical development and explicitly connecting it to your argument. For a prompt about 19th-century industrialization, contextualizing might mean discussing how Enlightenment economic ideas shaped the political conditions that made industrial capitalism possible — and then explicitly connecting that to the argument. A one-sentence mention at the start of the essay does not earn the point; the discussion must be developed and the connection to your argument must be stated.
What is a prompt?
A prompt is the assignment your teacher gives you — the question or task you are being asked to respond to. It might be a paragraph, a few sentences, or a single question. The verbs in it (analyze, argue, explain, describe) tell you what kind of work is expected.
What is a rubric?
A rubric is the scoring guide your teacher uses to grade your work. It lists the criteria — things like thesis, evidence, organization, and mechanics — and describes what strong, adequate, and weak work looks like for each one. If your teacher provides one, read it before you write; it tells you exactly what earns points.
