An institutional review board (IRB) is a formal committee that reviews and approves research proposals involving human subjects before data collection begins, making sure the study protects participants and follows ethical rules. In AP Research, gaining IRB approval is part of employing ethical research practices (EK 1.5D2).
An institutional review board (IRB) is a committee that checks your research plan before you're allowed to collect data from people. If your AP Research study involves human subjects in any way (surveys, interviews, experiments, focus groups, observations), an IRB looks at your proposal and asks the hard questions first. Is participation voluntary? Do participants know what they're agreeing to (informed consent)? Could anyone be harmed, embarrassed, or have their privacy violated? Are minors or other vulnerable groups protected? Only after the board signs off can you start gathering data.
The AP Research CED is direct about this. EK 1.5D2 states that laws, rules, and guidelines govern researchers, especially when studies involve humans and animals, and that scholars gain approval to conduct research with humans through an IRB. In practice, many AP Research schools set up their own IRB (often teachers and administrators) to review student proposals. Think of the IRB as a safety inspection for your method. It doesn't judge whether your research question is interesting; it judges whether your way of answering it treats people ethically.
The IRB lives in Unit 1 (Question and Explore), under learning objective AP Research 1.4.E, employing ethical research practices. The CED makes ethics non-negotiable. EK 1.5D1 says scholars have ethical and moral responsibilities when they conduct research, and EK 1.5D2 names the IRB as the specific mechanism for human-subjects approval. This matters for your project timeline too. EK 1.5C1 says scholars plan inquiry while accounting for deadlines, risks, and setbacks, and IRB review is exactly the kind of step that takes time. If your method involves people, you can't collect a single data point until approval comes through, so building IRB time into your plan is part of demonstrating the perseverance and planning skills in AP Research 1.4.D. Skipping ethics review isn't a shortcut; it can invalidate your entire study.

Designing and implementing a scholarly inquiry (AP Research 1.4.C) means aligning your method with your question, and the IRB is the checkpoint that asks whether that method is ethical, not just effective. A clever design that exploits participants isn't scholarly. The IRB keeps inquiry honest.
Sampling (Units 1 and 4)
How you recruit participants is an ethics question, not just a stats question. An IRB scrutinizes your sampling plan for coercion (like surveying your own friends who feel pressured to say yes) and for protections around minors, which matters a lot when most of your accessible population is high schoolers.
Intellectual property (Unit 1)
The IRB sits right next to intellectual property in the CED's ethics cluster. EK 1.5D2 covers approval to study humans, while EK 1.5D3 covers copyright and patent rules for using others' instruments and work. Together they define what 'ethical research practices' means in AP Research: protect people, and credit creators.
Generalizability (Units 1 and 5)
IRB constraints shape who you can study, and who you study shapes how far your conclusions stretch. If ethics rules limit you to consenting students at one school, EK 1.4.A1 reminds you that scope affects generalizability, so your discussion section needs to own that limitation.
AP Research isn't scored with a traditional sit-down exam. Your score comes from the Academic Paper and the Presentation and Oral Defense, and the IRB shows up in both. In your paper's Method section, you describe how you collected data ethically, including informed consent and, if your study involved human subjects, the approval process you went through. In the oral defense, panelists can ask how you handled ethical responsibilities, and being able to explain your IRB process (or explain why your study didn't require one, like a pure content analysis of published texts) signals you understand EK 1.5D1 and 1.5D2. Practically, the highest-stakes moment is before any scoring happens. If your method involves people, you need approval before collecting data, so the IRB is a gate you pass through, not a fact you memorize.
Both involve other scholars evaluating research, but they evaluate different things at different times. An IRB reviews your proposal BEFORE the study runs, asking whether the method treats human participants ethically. Peer review happens AFTER the research is done, when experts evaluate a finished paper's quality and rigor before publication. The IRB protects people; peer review protects the scholarly conversation. In AP Research terms, the IRB belongs to ethical practices (1.4.E), while peer review connects to evaluating source credibility (1.4.A), since peer-reviewed status is one marker of a credible source.
An IRB is a formal committee that reviews and approves research involving human subjects before data collection starts, and the AP Research CED names it directly in EK 1.5D2.
If your AP Research method involves people in any way, including surveys and interviews, you need IRB approval before you collect any data.
The IRB checks for informed consent, voluntary participation, privacy protection, and minimized risk of harm, with extra protection for minors.
IRB review takes time, so build it into your project timeline as part of the planning and perseverance skills in AP Research 1.4.D.
The IRB is different from peer review. The IRB approves a method before the study runs, while peer review evaluates a finished paper afterward.
Your Academic Paper's Method section and your oral defense should both show you understand the ethical responsibilities behind your data collection.
An IRB is a committee that reviews research proposals involving human subjects to make sure participants are protected. The AP Research CED (EK 1.5D2) says scholars gain approval to conduct research with humans through an IRB, so it's the official gate before human-subjects data collection.
Yes, if your method involves human subjects, including surveys, interviews, experiments, or observations of people. If you're only analyzing published texts, existing public datasets, or artifacts, you typically don't need human-subjects approval, but check with your AP Research teacher because your school sets the process.
No. An IRB evaluates the ethics of a proposed method before a study runs, while peer review evaluates the quality of a finished paper before publication. One protects participants, the other vets scholarship.
No. Data collected before approval is collected unethically and can invalidate your study. The CED frames IRB approval as something you gain before conducting research with humans, so plan your timeline around the review period.
Many schools running AP Research create their own review board, often made up of teachers, administrators, and sometimes community members, to review student proposals. The exact makeup varies by school, but the job is the same as a university IRB: assess risk, consent, and participant protection before approving the study.
