If they got paid by what they produced, they are way over paid.
Sometimes I think their pay should be compared with that of baby sitters, and not that of educators.
Okay! $3.00 an hour is an estimated rate for child care services. A typical teacher works a 7 hour day. So, 7 X $3.00 = $21.00 a day. Oh wait! that $3.00 per hour is per child. So, we then have $21.00 X 30 students, giving us $630.00 per day. Then, we take $630.00 X 184 work days and we get $115,920.00 per year.
Are you sure you want to pay teachers the same rate as a Childcare provider (which, for the record, $3.00 an hour is a very low estimate).
