Institutional Review Board (IRB) in AP Psychology

In AP Psychology, an Institutional Review Board (IRB) is a committee at a research institution that reviews a study before it begins to make sure it protects human participants' rights and welfare, through informed consent, minimal harm, confidentiality, and debriefing.

What is Institutional Review Board (IRB)?

An Institutional Review Board (IRB) is the ethics checkpoint for research on people. Before a psychologist at a university or hospital can run a study with human participants, they submit their plan to the IRB. The board reviews the risks, the benefits, and the procedures. Then it approves the study, asks for changes, or rejects it.

Think of the IRB as the bouncer at the door of a study. It checks a few things before anyone gets in. Will participants give informed consent? Is any harm kept to a minimum? Will their data stay confidential? If the study uses deception or a confederate, is that truly necessary, and will participants be debriefed afterward? This is exactly what the CED asks you to do in Science Practice 2.D. You evaluate whether a research scenario followed appropriate ethical procedures, and IRB approval is the first step in that process.

Why Institutional Review Board (IRB) matters in AP® Psychology

The IRB lives in Science Practice 2 (Research Methods and Design). That's a course-wide skill rather than one numbered topic, so it can show up attached to research from any unit. It most directly supports AP Psych Science Practice 2.D (evaluate whether a research scenario followed appropriate ethical procedures). It also connects to 2.B and 2.C, because ethics rules apply to experiments, surveys, correlational studies, and case studies alike. On the exam, the IRB is your go-to answer when a question asks who decides whether a study is ethical enough to run, or what step a researcher skipped.

How Institutional Review Board (IRB) connects across the course

Informed Consent, Confidentiality, and Ethics (Science Practice 2)

These are the rules, and the IRB is the group that enforces them. When an FRQ asks how a researcher protected participants, naming informed consent or confidentiality explains what was done. Naming the IRB explains who signed off on it.

Deception, Confederates, and Debriefing (Science Practice 2)

Some classic studies only work if participants don't know the real purpose, sometimes with a confederate playing a role. An IRB can approve deception only when the study couldn't work without it and the risk is low. Debriefing is the required cleanup step that tells participants the truth afterward.

Experimental vs. Non-Experimental Designs (Science Practice 2)

IRB review isn't just for lab experiments with a control group. Surveys, correlational studies, and case studies still involve real people, so they still need approval. That's why ethics questions can be attached to any research design the exam gives you.

Peer Review (Science Practice 2)

Peer review and the IRB both put a study in front of outside judges, but at opposite ends of the research timeline. The IRB checks ethics before data collection. Peer review checks scientific quality after the study is done, before it gets published.

Is Institutional Review Board (IRB) on the AP® Psychology exam?

The IRB shows up when the exam asks you to evaluate the ethics of a research scenario (Science Practice 2.D). In multiple choice, expect stems like "Before beginning the study, the researcher should first obtain approval from..." or "Which group is responsible for ensuring a study protects participants?" The answer is the IRB.

In free response, the term appeared in the 2018 SAQ Q2. That question described a survey about the physical and psychological health of high school students, including items on stress levels and absences. Scenarios like this one, with minors answering personal questions, are a natural setup for ethics. You may need to explain how the study protects participants, such as getting consent from parents and the students themselves, keeping answers confidential, and getting IRB approval before collecting data.

To earn the point, apply it to the scenario. Don't just write "the IRB makes it ethical." Say what the IRB would require in this specific study and why.

Institutional Review Board (IRB) vs Peer Review

Both involve outside experts judging a study, so students mix them up. The difference is timing and purpose. An IRB reviews a study before it starts and asks whether it's ethical and safe for participants. Peer review happens after the study is done and asks whether the methods and conclusions are scientifically sound enough to publish. A study can pass IRB review and still get rejected in peer review for weak methods.

Key things to remember about Institutional Review Board (IRB)

• An Institutional Review Board (IRB) is a committee that must approve research on human participants before the study begins.

• The IRB checks for informed consent, minimal harm, confidentiality, and debriefing, which are the core ethical guidelines in AP Psychology.

• An IRB can approve deception or the use of a confederate, but only if it's necessary for the study and participants are debriefed afterward.

• IRB review applies to every research design with people, including experiments, surveys, correlational studies, and case studies.

• The IRB reviews ethics before a study, while peer review evaluates scientific quality after a study, before publication.

• On FRQs, tie the IRB to the specific scenario by explaining what protections it would require for those participants, not just naming it.

Frequently asked questions about Institutional Review Board (IRB)

What is an Institutional Review Board (IRB) in AP Psychology?

An IRB is a committee at a research institution that reviews studies involving human participants before they begin. It makes sure the study protects participants' rights and welfare through steps like informed consent, confidentiality, and debriefing.

Does an IRB ban all deception in psychology research?

No. An IRB can approve deception when the study couldn't work without it and the risk to participants is low. The researcher must debrief participants afterward and explain the true purpose of the study.

How is an IRB different from peer review?

An IRB reviews a study's ethics before any data is collected. Peer review evaluates a finished study's methods and conclusions before it gets published. One protects participants, and the other protects the quality of the science.

Do surveys and correlational studies need IRB approval?

Yes. Any research with human participants needs ethical review, not just experiments. The 2018 AP Psych SAQ Q2 used the term in a survey of high school students' stress and absences, which shows that non-experimental studies raise ethics questions too.

Is the IRB on the AP Psych exam?

Yes. It falls under Science Practice 2.D, which asks you to evaluate whether a research scenario followed appropriate ethical procedures. It can appear in multiple-choice questions and in FRQs, including the 2018 SAQ Q2.
