I agree that in-class training is always the best, but it's not the most viable option for me. I've worked as a technician before; the state in which I live does not require one to be licensed, but I would like to sit for licensure for myself and for potential career growth. I know that Purdue offers an online technician course and I believe Penn Foster does as well, although I'm not sure whether their accredited. Thank you for the quick responses.
