EBQ AP Psychology: Evidence-Based Question Guide
The EBQ (Evidence-Based Question) is the second free-response question on the redesigned AP Psychology exam — the longer one. You get three sources, make a claim, and defend it with cited evidence and applied psychology. Here's the 7-point rubric, the claim-evidence-reasoning formula, and the source-citation rule that trips students up.

What Is the EBQ?
The EBQ gives you three short summaries of peer-reviewed sources on a single theme. Your job is to take a position — a defensible claim — and back it up using evidence pulled from those sources, then explain why that evidence supports your claim by applying a psychological concept from the course. It's essentially a tight, evidence-cited argument, and at 7 points it matches the AAQ for weight while giving you more time.
The EBQ Rubric (7 Points)
The points come in three parts, and the structure is the strategy:
| Part | What it asks | Pts |
|---|---|---|
| A · Claim | State a clear, defensible claim that answers the prompt. | 1 |
| B · Evidence | Cite specific evidence from one source. | 1 |
| B · Reasoning | Explain how that evidence supports your claim, applying a psychological concept. | 2 |
| C · Evidence | Cite specific evidence from a different source. | 1 |
| C · Reasoning | Explain how it supports your claim, applying a different concept. | 2 |
The critical rule: Parts B and C are parallel but must use different materials — a different source and a different psychological concept in each. Think of them as two separate pillars holding up the same claim.
The Source-Citation Rule (Don't Lose Easy Points)
Evidence only counts if you say where it came from. Writing "(Source 2)" or "According to Source 2…" earns the evidence point; describing the same finding without naming the source does not — even if it's completely accurate. Cite every piece of evidence, every time.
How to Answer the EBQ: Claim → Evidence → Reasoning
- Read all three sources (first ~15 min). Note each source's main finding and which psychological concept it connects to. Pick the two strongest, most different sources for Parts B and C.
- Write a one-sentence claim. Make it a clear position that directly answers the prompt — not a vague restatement.
- Build pillar B. Cite a finding from one source, then explain how it supports your claim using a specific course concept (name the concept).
- Build pillar C. Cite a finding from a different source and apply a different concept. Reusing the same source or concept forfeits the parallel points.
- Watch the clock. At ~45 minutes (after ~25 for the AAQ), the EBQ is the bigger time investment — budget so you finish both reasoning sections, where most points live.
Common EBQ Mistakes
- Forgetting to cite the source — the single most common way to lose evidence points.
- Reusing the same source or concept in both B and C — only one will count.
- A vague claim that doesn't take a clear position.
- Evidence without reasoning — you must explain how it supports the claim, naming a psychological concept. Reasoning is 4 of the 7 points.
- Summarizing all three sources instead of arguing — the EBQ rewards a focused argument, not a book report.
Because reasoning means applying real concepts, the EBQ rewards deep understanding over memorization — exactly what running the experiments builds. Strengthen your concept base with the study guide and the units overview.
EBQ — FAQ
Is the EBQ harder than the AAQ?
Most students find it more demanding because it's longer, source-heavy, and requires applying concepts in your own reasoning — but it's also where understanding (not memorization) pays off most. The extra time (about 45 minutes) is built in for that reason.
How many points is the EBQ worth?
7 raw points — 1 for the claim, plus 1 evidence and 2 reasoning in each of Parts B and C. With the AAQ's 7 points, free response is 14 raw points and one-third of the exam.
What's the first free-response question?
The AAQ (Article Analysis Question), which analyzes a single study. See the exam timing guide to plan both.
