“I spent 3 weeks as Assistant Principal for summer school and then 2 weeks taking a class”
I am sure this was not in your salary and you were paid extra.
In Texas Principle in Middle School makes around $ 105K for example here is 3 without much looking.
Polytechnic HS Principal Hs $104,860
Southwest HS Principal Hs $104,860
Diamond HS Principal Hs $104,860
My information is from this website. When this was released in the local paper the Texas Public Employees went nuts and tried to remove it.

Yes I was paid extra, it amounted to just under minimum wage with the extra prep and follow up we had to do. Once again it was my choice, and the money I made from that paid for the class I took. Our district is a relatively poor rural school district and does not have extra funds.
