Hello! I have a question for school nurses in PA - is it possible to become certified with the NBCSN and not enroll in classes for certification at a college?? Like, I just want to take the test and not get half a master's degree. Is that kosher? FWIW I work at a private school and certification is not required, but I kind of want to do it anyway. And I do not want to pay more than whatever it costs to take the test!
