Within 7 to 10 days after you apply, you should find your initial assignment information in the eRA Commons. You can monitor the status of your application, including the study section to which it is assigned, on the Status Tab in eRA Commons.
At first, the Status Tab may show your integrated review group instead of your specific study section. During the next few days, the Division of Receipt and Referral (DRR) in NIH’s Center for Scientific Review will update this information with the study section assignment. If you don't see your study section assignment within 2 weeks, call DRR at 301-435-0715.
