AP US History · Lesson 45

Earn each SAQ point with economical writing

How the three SAQs work, what each task verb requires, how to read each source type, and the four errors that cost points even when the facts are right.

Start with the big idea

A student can know a fact and still lose the point. The short-answer question tests that gap more directly than any other task on the exam: three tight parts, source material to read correctly, and almost no room for a vague claim to hide inside.

Each SAQ has three parts, and each part is scored independently. A weak answer on part A does not drag down a strong answer on part B. That independence is a real advantage if you use it: never skip a part because an earlier one went badly.

What each SAQ actually asks for

The exam gives you three short-answer questions in forty minutes, and you must answer all three. The three questions focus on different historical periods and together may draw on developments from 1491 through 2001. Each one comes with a different kind of source:

  • Question 1 includes two secondary text sources, usually historians' interpretations.
  • Question 2 includes a primary text source.
  • Question 3 includes a primary or secondary non-text source such as a map, image, chart, or graph.

Each SAQ part is scored according to the task verb and the scoring guideline for that part. A describe part can earn its point with a historically accurate, specific description. An explain part must state a relevant relationship and explain how or why it works. Some parts require outside evidence, while others ask what a source shows. Do not force every part into a claim-plus-evidence-plus-explanation formula when the prompt does not require all three.

Read the source before you answer

Note the source's date, author, and type before you read the questions. A secondary source from a historian writing decades after an event answers differently than a primary source written in the moment. That context often tells you exactly what kind of evidence the question expects, before you have written a single word of your answer.

Here is a quick routine for each of the three source types:

  • Two secondary sources: Ask what each historian claims, and what the two disagree about. Most Question 1 parts turn on the difference between the two interpretations and on which outside development would support each one.
  • One primary source: Ask who wrote it, when, to whom, and why. The date tells you which period's evidence belongs in your answer.
  • A non-text source: Read the title, labels, units, and dates first. For a table or chart, identify the direction of the trend before you try to explain it.

Know what the command word requires

Describe asks you to identify a relevant characteristic, development, or pattern with enough specificity to show what it is. Explain asks you to add how or why a relationship, cause, effect, similarity, difference, or change exists.

Do not add explanation where the prompt only asks for description merely to satisfy a template, and do not stop at description when the prompt asks you to explain. Answer the verb the prompt actually uses. A describe answer with no explain reasoning, or an explain answer with no specific cause, both lose the point even when every fact in the sentence is accurate.

Build each SAQ point in three sentences or less

Most SAQ parts can be answered in two or three efficient sentences, but there is no official sentence-count rule. Write enough to satisfy the command word and make the historical relationship explicit. A named fact helps when evidence is required, but a correct response does not earn or lose the point because it follows a fixed sentence formula. Naming a fact is not the same as using it when the prompt asks you to explain.

A strong compact response has three working parts: a direct claim, specific historical evidence when the part requires it, and an explicit relationship that shows how the evidence answers the prompt. Compare two answers to a part that asks you to explain a reason for the passage of a law. The weak answer says, "Reformers wanted change and Congress responded." The strong answer names the reformers, the specific law, and the pressure that connected them. The first sentence is true but gives the scorer nothing to credit.

Common ways SAQ responses lose points

The four SAQ errors
ErrorWhat it looks like on an SAQ
Specificity errorThe answer says "a law" or "a movement" instead of naming the actual act, group, or person.
Evidence-link errorThe right fact appears, but the response never connects it back to the claim being made.
Chronology errorEvidence comes from outside the period the source or prompt sets.
Source-reading errorThe response paraphrases the source's content instead of using its date, author, or purpose to answer the question asked.

Practice habits that pay off

Work the practice SAQs and the three worked models in the question set below under a timer of about thirteen minutes each, including the time it takes to read the source. After you finish, compare your parts to the model answers one at a time. For each part, decide whether you would have earned the point, and if not, name which of the four errors cost you. Over several sets, you will see the same one or two errors repeat. Fix those first.

Finally, keep your answer inside the window set by the source and the prompt. If a source is from 1912, evidence from the 1930s will not help you unless the part explicitly asks for a connection across periods. When the prompt asks for a continuity or a connection to a broader pattern, name the span of time you are connecting and say what stayed the same.

The memory checks at the end of the set ask you to say these ideas in your own words. Answer them without looking back at the lesson, then check your answers against the model.

Practice set

Exam mode

Exam mode runs on the clock of the real section and holds the explanations until you submit. You then see your score and an explanation for each question.

  • The exam covers 5 questions and 11 written responses.
  • A single timer of 46 min runs for the whole set.

Study mode

Study mode lets you answer each question at your own pace and shows the explanation as soon as you check your answer.

  • The 16 questions appear in a new order each session.
  • The explanation opens when you check each answer.
