AP Psych Evidence-Based Question: How to Score All 7 Points

The AP Psych Evidence-Based Question (EBQ) explained: the claim, evidence, and explanation points, a worked example, and a 45-minute plan for test day.

The AP Psychology Evidence-Based Question (EBQ) is the second free-response question. You read three short sources on a psychological topic, make a claim, and support it with evidence from two different sources, explaining each piece with a psychological concept. It is worth 7 points, and four of those points come from the explanations.

That last fact should shape how you spend your time. Here is how the EBQ is scored, how to write each part, and a full example.

What is the AP Psych Evidence-Based Question?

The revised AP Psychology exam includes a 70-minute free-response section with two questions: the Article Analysis Question and the EBQ. Because the EBQ involves reading three sources and building an argument, plan on roughly 45 minutes for it.

Each source summarizes a study or body of research related to the prompt. The prompt asks you to take a position, often about the effect of something or a recommendation, and defend it.

How is the EBQ scored?

College Board's scoring guidelines break the EBQ into five scored parts.

PartTaskPoints
AA defensible claim that responds to the question1
B(i)Specific, accurate evidence from one source, correctly cited1
B(ii)Explain how that evidence supports the claim, applying a psychological concept, theory, perspective, or research finding2
C(i)Specific, accurate evidence from a different source, correctly cited1
C(ii)Explain how that evidence supports the claim, using a different psychological concept2

For each explanation part, the first point comes from explaining how the evidence relates to your claim. The second comes from correctly applying a psychological concept to show why it supports the claim.

A few rules from the scoring guidelines matter in practice:

  • A definition alone does not earn the application point. You must apply the concept to the evidence.
  • Some research terms do not count as concepts for the application point, including independent variable, dependent variable, experiment, confederate, and meta-analysis.
  • The concept must come from the AP Psychology course framework.
  • Your claim earns its point on its own, even if your evidence later falls short.
  • Small numerical slips are forgiven if the direction of the result is right.

How do you write a strong EBQ claim?

Your claim must take a position. Restating the topic, or saying "it depends," does not earn the point.

  • Weak: "Social media affects teenagers."
  • Strong: "Limiting social media use is likely to improve adolescents' sleep quality."

Choose your claim after skimming all three sources. Pick the side backed by the two most specific, quantifiable results, not the side you personally believe.

How do you cite evidence in the EBQ?

Evidence must be specific and accurate and must be cited so the reader knows which source it came from. A simple parenthetical works: (Source A) or (Smith, 2019), whatever the prompt provides.

Strong evidence names a group, a measure, and a direction of difference.

  • Weak: "Source B shows exercise helps."
  • Strong: "Participants who walked for 30 minutes daily reported lower stress scores than those who did not exercise (Source B)."

For Part C, use a different source from Part B. That is the safest way to guarantee the evidence counts.

How do you earn the 2-point explanation?

Use this three-step sentence structure every time:

  1. Connect: "This supports my claim because…"
  2. Name the concept: identify a specific term from the course.
  3. Apply it: explain how the concept accounts for the result in the source.

For B(ii) and C(ii), pick two concepts from different areas if you can (for example, one biological and one cognitive). Using the same concept twice will cost you the second application.

EBQ worked example

Here is a practice prompt written for this guide; the sources are simplified and hypothetical.

Prompt: Using the sources, develop and justify a claim about whether schools should start later in the morning for high school students.

Source A: Students at schools that shifted start times later slept more on school nights than students at schools that did not. Source B: Students who slept fewer hours scored lower on a test of next-day recall. Source C: Students reporting more sleep also reported fewer symptoms of low mood.

Model response:

A. High schools should start later in the morning because later start times are likely to improve students' memory and mood.

B(i). Students who slept fewer hours scored lower on next-day recall tests than students who slept more (Source B).

B(ii). This supports my claim because later start times would let students sleep longer, protecting their recall. Sleep plays a role in memory consolidation, the process of stabilizing new memories, so students who lose sleep have less opportunity to consolidate what they learned the previous day.

C(i). Students who reported getting more sleep reported fewer symptoms of low mood (Source C).

C(ii). This also supports my claim, because a later start would align school with adolescents' circadian rhythm, which shifts later during puberty. Forcing teens to wake before their biological clock is ready cuts sleep short, and the source links shorter sleep with poorer mood.

Notice the pattern: one result per part, a clear citation, a named concept, and an explanation of how that concept produces the result.

How should you spend 45 minutes on the EBQ?

  1. Minutes 0–3: Read the prompt and underline exactly what it asks you to claim.
  2. Minutes 3–15: Read all three sources. Mark the single strongest result in each.
  3. Minutes 15–20: Choose your claim and two sources. Jot one concept per source.
  4. Minutes 20–40: Write Parts A through C, labeling each one.
  5. Minutes 40–45: Check every citation and confirm your two concepts are different.

What are the most common EBQ mistakes?

  • Defining instead of applying. "Memory consolidation is…" with no link to the source caps you at 1 point.
  • Vague evidence. "The study showed it helps" is not specific.
  • Using research-method terms as your concept. "This was an experiment" earns no application credit.
  • Reusing the same concept in B(ii) and C(ii).
  • Writing an essay. Labeled parts make it easy for the reader to find each point.

The best preparation is a deep, flexible concept vocabulary. If you can explain a result using biological, cognitive, developmental, and social ideas, you will never be stuck. Our guides to classical vs operant conditioning and how to get a 5 on AP Psychology are good places to build it.

How Ivystar can help

The EBQ rewards a skill most students never practice explicitly: connecting a data point to a named concept in two sentences. In our AP Exam Prep program, tutors from schools like Harvard, Penn, and Stanford score your practice EBQs against the rubric and show you how to earn the explanation points.

Frequently asked questions

How many points is the AP Psych EBQ worth?+

The Evidence-Based Question is worth 7 points: 1 for the claim, 1 for each of two pieces of cited evidence, and 2 for each of two explanations.

Do I have to use all three sources in the EBQ?+

No. You need evidence from two different sources, one for Part B and one for Part C. Reading all three helps you choose the strongest claim.

Can I use the same psychological concept twice in the EBQ?+

No. Part C(ii) requires a different concept from Part B(ii) to earn full credit, so plan two distinct concepts before you write.

Does my claim need to be the right answer?+

There is no single right claim. It needs to be defensible and responsive to the prompt, and the claim point can be earned even if your later evidence falls short.
