Eligibility Criteria

Eligibility may vary by award type, please carefully review the grant opportunities page. Select the grant to which you wish to apply to see grant-specific eligibility. You will find eligibility criteria applicable to all ATS grants on the eligibility criteria page.

If you believe that you have a special circumstance in regards to eligibility (e.g. Being beyond 12 years from your degree but took time off for parental leave or military service), please send a brief statement explaining your situation to before proceeding with the letter of intent. 

Multiple Submissions

Applicants may submit multiple scientifically distinct letter of intent (LOI) applications, but ATS will extend at most one invitation to submit a full grant application to each applicant. We recommend you limit your number of submissions to focus on one quality, well-prepared grant proposal.

You may not submit the same application to multiple categories. In choosing a category for your submission, please review the criteria for each award and pick the category most appropriate to your budget and timeline. If you are eligible for a targeted grant that is appropriate to your budget, we recommend you apply to that category over the unrestricted grants which receive the majority of applications.
