Complete the continuing review form. The continuing review form can be found on the Forms & Templates page.
Submit the completed continuing review report form and, if needed, any other supporting materials directly to the IRB for review.
If the IRB asks for revisions or additional information, prepare revised/additional materials and submit them to the IRB, along with a cover memo itemizing the changes/additions.
Once you have appropriately addressed all of the IRBs concerns, the IRB will issue an approval memo, and you are authorized to continue your research past the current expiration date.
