Research studies involving human subjects require IRB review. Evaluative studies and activities do not. However, it is not always easy to distinguish between these two types of projects and many projects frequently have elements of both. Therefore, the decision about whether review is required should be made in concert with the IRB.
If you think that your project is limited to evaluation activities and therefore not subject to IRB oversight, please submit a Determination Form. This form as well as additional information for when IRB review is required can be found on the "Does your study require IRB review?" webpage. Specifically, the Scenarios and Research Versus Program Evaluation Checklist found on the bottom of this page may be useful.
