I am unhappy I am not clearer about this, though I think I am beginning to get the gist of things, which clearly may vary in each state. We DO have, here in OH, STNA's, state tested nursing assistants. They are registered with the state...but I am struggling to find info on "certified" nursing assistants OR "certified" home health aides. I am increasingly being led to conclude that many medical/dental assisting "colleges" that are typically private/for-profit have short term courses for these fields and the courses are covered by grants the student(s) qualify for. In the end, when they refer to themselves as "certified" I think it may mean nothing more than a paper certificate their training source handed them. Anyone have any thoughts/experience with this??
