Submitting Reference Letters

If you are submitting a reference letter for an LRP applicant, see instead of this topic.

If you are asked to submit a reference letter for someone (meaning you are a 'referee'), you can do so using eRA Commons. Reference letters can be submitted any time after the Funding Opportunity Announcement (FOA) is posted and no later than the submission deadline. Reference letters cannot be accepted through any means other than eRA Commons.

You do not need to log in to eRA Commons to submit a reference letter for an applicant. Although you - as the referee - do not need a Commons role to submit a reference letter, the candidate on whose behalf you are writing must have a valid Commons account and hold the principal investigator (PI) role. If your candidate has no Commons account or does not have the PI role, you receive an error when attempting to submit a letter.

The candidate's signing official (SO), accounts administrator (AA), or administrative official (AO) at the institution must assign the PI role to the candidate's Commons account.
