Does your company where you work as a CNA offer any scholarships
or maybe even a nursing school loan?
I would first ask your HR person, but if they say no ask your Director of Nursing or Administrator. Tell them you're in a bind (for whatever reason) and you really want to go to nursing school. Some companies have systems set up to offer loans to employees.
I would also look into associations & organizations in areas you are interested in. A lot of them offer scholarships to those pursuing nursing school.
I don't know if you're in Massachusetts, but there is a company called Mass Senior Care that offers scholarships for nursing staff working in long term care.
Hope this helps! Good Luck!
