About US Department of the Interior

Who can apply to US Department of the Interior calls?

It is set per call, not per programme. 100% of these calls accept a single applicant; 0 require a consortium. Where the conditions state the requirement we quote the sentence they state it in; where they do not, we infer it from the type of action and mark it as inferred, and an inferred value never appears without that mark.

What does the budget figure mean?

It is the sum of what the funder published per call, in the funder's own currency, converted once at the European Central Bank rates this build holds. Calls that publish no budget contribute nothing rather than an estimate, so the total is a floor, not a guess.

How often does this page change?

The corpus is re-synced nightly and the site is rebuilt with it. Cut-offs and countdowns are recomputed at build time, so a call that closed since the last sync leaves this page rather than sitting here with a stale date.

Can I see only the calls I could win?

Yes, the fit check reads every call on this page against your organisation on the gates that decide admissibility, and it runs in your browser with no account. Calls that block you are shown with the condition that blocks them, because sometimes it is one you can change.
