I don't know of any scholarships but I know a lot of medical facilities offer assistance in school costs. The hospital I used to work for offered assistance for any part time lpn to finish rn if they agreed to work for at least three years after degree completion. Different hospitals have different rules though. Some pay up front and require a contract that states you have to pay them back if you quit or are fired, others pay after the set years have been worked, etc.
If you are working anywhere now I'd ask about education reimbursement plans.
And there are thousands of small scholarships available online for pretty much everything, $1000 here and $500 there can add up quickly if you take time to write the essays
