How do I know if my high school can nominate for a jefferson scholar?

Is there a list of what high schools are eligible to nominate for a jefferson scholar? I see a list for several other top merit based awards (like Morehead-Cain) Thanks

Per their website:

If there is one in the public domain, it may not be up-to-date, as there are 4000 high schools eligible to nominate.
