Regarding what to charge for teaching outside of school...
I teach a Saturday school art class for high school students at a local
college that is free to students but is supported by the local school
district. The class runs for 6 Saturdays and each of the sessions last for
3 hours. I combine both traditional art studio and computer art lessons /
teaching and learning strategies in my program.
The district pays me $1800 for the 18 hours, out of which I spend $400 for
art supplies that I disburse among the students during the last class. That
leaves about $78 an hour. In addition, it is about an 80 mile round trip
for me each Saturday or 480 miles total. Factoring gas and mileage into the
equation figuring on $.40 a mile, that reduces the hourly rate to roughly
$67 per hour. My class size is roughly 20 students. If each student was to
pay an equal portion of that, their cost would be $3.35 an hour X 18 hours
which would equal $60.30 for the 6 Saturdays.
Given all of that, you certainly will have to figure on material costs,
travel expenses, and number of hours you wish to set to make this worthwhile
for you.
