Protocol Decision Tree

This tool was developed to help investigators identify the most likely level of IRB review for their new study submission. Please note that a submitted study must be reviewed by Human Subjects Office (HSO) staff, and the level of review may change based on additional information at that time.

When used correctly, the following yes/no questions (and a few multiple choice questions) will provide guidance that is accurate for most studies, but cannot be relied upon for a completely accurate determination in all cases. In some cases, additional study information that is not captured through the following questions will result in a different level of review than provided by this tool.

Please review HSO guidance and learning guides for more information on the submission process, and contact HSO staff with any questions. When you are ready to begin the process, please click the button below.
