Overview of R01 Process and Due Dates

This application to funding timeline is for Unsolicited, Investigator-Initiated R01s (not applications responding to initiatives) by review cycle for fiscal year 2025 funding.

For other application types or other years, go to the NIH Standard Due Dates for Competing Applications. Also check other NIAID Timelines & Due Dates.

The text below uses actual R01 submission deadlines for investigator-initiated applications. We based them on NIH standard due dates. If a standard date falls on a weekend or holiday, we adjusted it to the next business day.

Preparation Stage

Step 1. Prepare your application

First learn about Types of Funding Opportunities and Understand NIAID Research Priorities. Then get advice from NIAID's Apply for a Grant and mentors.

Since your institution may take days, weeks, or months to process a grant application, get your internal due date from your business office. Also check the timing for any required NIH or NIAID preapprovals before you apply. Learn more at Some Deadlines Are Before the Application Due Date.

Based on your internal deadline and accounting for preapproval steps, we recommend that you allow at least this much time to Prepare Your Application and Apply for a Grant:

  • Two months: Planning and writing.
  • One month: Getting feedback.
  • Two weeks: Checks and edits.
