Pre-Proposals/Letters of Intent

A pre-proposal or letter of intent (LOI) outlines an understanding between a sponsor and a PI which they intend to formalize.

Non-Binding Pre-Proposals/LOIs

The majority of sponsor requests for pre-proposals/LOIs may be submitted directly by the PI/DLCI to the sponsor without RAS endorsement. These pre-proposals/LOIs are non-binding to MIT, will not result automatically in an award, and do not require institutional sign-off in RAS. 

Pre-Proposals/LOIs Requiring RAS Review or Signature

Pre-proposals/LOIs must be entered and routed in KC if they:

  • Are from international sponsors
  • Require institutional signature or submission by an authorized official (such as in NSF Research.gov, NSPIRES or Grants.gov Workspace)
  • Include binding commitments
  • May result automatically in an award

If you aren’t sure about whether your pre-proposal/LOI requires RAS review and submission, please contact your RAS CA. PIs/DLCIs should route pre-proposals/LOIs as early as possible. 

Limited Submissions

For proposals responding to limited submission opportunities, contact Research Development.
