CNA certification

Hi all! New to this, but had a question regarding CNA certification. I;m a stay at home mom, and I have a daughter with a medical condition. She'll need surgery in the mext month or so (possibly sooner) so taking classes or training outside the home is not possible at this time. I see that Stratford Career Institue offers a Nursing Assistant program with all the courses geared towards that topic. Is it possible to study this at home and be able to sit for the state certification? Will studying at home have any sort of benefits for when I can return to work? I don't want to waste money if its not going to help me in anyway. I'm sorry this is so long, but I would appreciate any information anybody has! Thank You!!
