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.
