What state do you live in? Here in NYS, you don't need a GED, but a lot of facilities require one for hiring purposes. The hospital I work in requires a GED or HS Diploma, and a lot of the area nursing facilities do as well. Just check the facility and see what the requirements are.
I live in GA, and when I was a CNA, none of my employers ever ask to see my HS diploma or to see a GED. However, most applications, if not all, ask about graduating HS, college and or tech school. But if they don't ask to see anything how do they know?
That's a good question and I'm not sure of the answer. I've never been asked to show my HS Diploma. I'm not sure if that's something thta would show up in a background check or not though. Better safe than sorry...I would definitely not lie about education to get a job. It seems like it could come back and bite you in the butt somehow.
I wouldn't lie either. There are state sites (I know in Florida they do) where you can take you GED test as well as complete whatever classes to get your HSD. I would, it may not seem important, but a lot of employers (I haven't seen one that doesn't) require it. FYI it does show up in background checks, as long as they are looking for it anyway.
