I was asked about my educational background and job experience. Also was thoroughly checked for any issues in my background that would be negative for a teacher. Sent for fingerprinting and had to fill out several forms. Biggest issue was the fact it was a several step process, but the office personnel giving instructions would only tell you about one thing at a time. Made you feel as if you were a child & having secrets kept from you. Also pay is better if you have a college degree, but it’s still not great! A lot of other subs I met did it for extra income or to be closer to their children.
