Hi!
I always encourage pilots to substitute teach.
Wisconsin has the strictest requirements to be a sub, which is a 4-yr. degree. Most states have a number of college credits required, such as 60 credits beyond HS.
Most places need subs bad. I have subbed K-12 in 15 school districts. In NE WI where I live they paid about $100/day 2 years ago.
I would say subbing in the lowest grades are the most difficult, as you're always doing stuff. The highest technical HS subjects, such as Calculus, Chemistry or Chinese III are easy, because the teachers assume that you'll know nothing about the subjects, so they'ver prepared the lesson plans accordingly.
School districts typically have a computer call you in the morning. If you don't answer, they go to the next person. If you answer, it'll ask you if you want to sub in a certain position at a certain school. You can say yes or no.
Some districts call you, so you can call them ahead of time with your schedule to tell them which days you're available.
It's great to sub 3-4 days/month and make an extra $3-$400 dollars for the month.
