Find all current NIAID paylines in the table below. Our most recent update was on December 17, 2024: We increased fiscal year (FY) 2025 interim paylines for all fellowship award (F) grant types.
Paylines are funding cutoff points for the grant application types listed below. Following the Financial Management Plan, NIAID funds most applications in order by percentile (R01 awards and fellowships) or overall impact score (all others). Each FY, NIAID sets initial paylines conservatively and sets final paylines later. We may fund beyond the paylines near the end of a FY. Learn how NIAID Paylines and Budget Information Changes Throughout the Year.

Note: As of FY 2025, the NIAID funding strategy includes paylines by activity code for most research training and career development funding opportunities. In addition, beginning in FY 2025, NIAID will use the percentile rank in the paylines for fellowship applications (e.g., F30, F31, F32). This kind of ranking permits comparisons across scientific review groups that may have different scoring behaviors. Read more about Paylines and Percentiles.
