Hello! I grew up in Conover, went to school in Claremont, and I think I can help you.
I got my CNA 1 at CVCC. It was a night class, about 6 months long. They also had a daytime class. Go to the west building off of 64/70, near the stoplight (continuing ed class, the building with the playground out front).
Also, check at the Lutheran Home off of Springs Road. They used to have a CNA class that was available also. Good luck!
PS- I worked at Abernathy Center in Newton after graduation. I LOVED it!
