After IRB training is completed, you must choose which category of review your research requires.
There are four main categories of IRB review:
Below provides a general summary of each these four review categories. For more details and examples of each review, see our Types of IRB Review.
An exempt review doesn't require monitoring by the IRB. Exempt categories are outlined by the Department of Health and Human Services in 45 CFR 46.101(b).
It is important to note that while a project may be exempt from IRB regulations, the ethical principles of conducting human subject research still apply. More importantly, it is not up to the researcher to determine whether a project is exempt. Researchers that believe their project is exempt should submit their research application to the IRB, selecting exempt for their category of review.
Exempt reviews are carried out by the IRB Chair or their designee.
An expedited review is typically carried out by the IRB Chair or their designee.
It involves research that doesn't involve more than minimal risk to participants. Minimal risk is defined as: the probability and magnitude of harm or discomfort anticipated in the research are not greater than those encountered in daily life or through the performance of routine physical or psychological exams/tests.
While the IRB Chair can review and approve expedited review research, the Chair cannot disapprove research proposals without moving the research project to full review.
A full review is necessary when the IRB Chair deems participant risk is more than minimal or when the Chair disapproves an expedited review and moves the research project to full committee review.
A continuing review is necessary when the research project is not complete after one year.
A continuing review reevaluates a project's:
If it is deemed that there is less than minimal risk for participants, the continuing review will be reviewed by the IRB Chair. If there is more than minimal risk, the project will be reviewed by the full IRB.
Full reviews require the researcher to provide a summary protocol and a status report on:
