It depends on what your state board of nursing has to say.

Do yourself a favor: get your GED if you think that you cannot get through high school. If you ever want to be a nurse (and this applies for both RN and LPN) will need a high school diploma or a GED.

It is very hard to get a job without a high school diploma or a GED nowadays.

You can get your GED if you feel that you are having trouble in High school. Then you can apply to get your CNA. My question is why do that, go all the way and go for RN.

Good Luck to you hun

It requires a high school diploma to be a CNA as does 99% of any other job you look for-If you can’t deal with high school whwt makes you thin you’ll be able to deal with CNA training

Im not sure how it is now but it used to be that if had your GED that was as good as a diploma.
If you drop out and get your ged then you should have no problem with doing what you need to do to become a CNA.

Seriously, three months isnt that long to hold on. Consider your options, all the pros and cons of doing what your thinking about doing. Look into the GED program before doing anything hasty
