Workforce 1 will deny you a voucher for CNA/ NAA training if you have not had any previous experience in the field. In my case, before becoming unemployed (as an Executive Assistant), I was attending classes at a community college for nursing. I had to show them that I had finished my prerequisites and had declared nursing as a major. Although, when I attended their grant seminar, they stated that they would also accept time you spent as a volunteer or any type of internship in that profession. However, your advocate will determine if it is a sufficient amount of time or experience. I hope that helps....
