Yeah. I used to substitute teach when I was unemployed. Was pretty easy process. I had to apply to the state for a certificate which was basically them verifying I had the degree I claimed from an accredited instituion. then I stopped at the high school administrative office and told the secretary I wanted to be on the list and showed my certificate and gave some preferences (I had a bs so asked for science and math but ultimately did a variety of other subjects and did enjoy them). I stopped though because now I would need to go to the district office and do a bunch of paperwork and have to pay them to do a background check and get finger printed (the state cert had a fee but it was small and one and done while every district would need its own check). The cost was such that if I susbstituted one day im not sure it would cover it. It was fine doing it but it became much more of a hassel and I could get a job quickly and end up losing money on the deal (I mean again the state cert could still lose money but it was like a super token sum. Maybe 5 or 15 dollars). Kids wear their ids around their necks now. ugh.
