Five Skill Categories

What students must practice on the exam

Skill 1

Developments and Processes

Identify and explain historical developments and processes. The foundational skill that every other skill builds on.

Skill 2

Sourcing and Situation

Analyze sourcing and situation of primary and secondary sources — author, audience, point of view, purpose, and historical context.

Skill 3

Claims and Evidence in Sources

Analyze arguments in primary and secondary sources, including the claim, the evidence used, and the limits of that evidence.

Skill 4

Contextualization

Analyze the context of historical events, developments, or processes — what came before, what was happening simultaneously, and what followed.

Skill 5

Making Connections

Use the three reasoning processes (Comparison, Causation, Continuity and Change Over Time) to connect events across periods and themes.

Skill 6

Argumentation

Develop an argument: thesis, supporting evidence, reasoning, and addressing counterarguments. The DBQ and LEQ both reward this skill heavily.
