Good fucking grief! Did you come up with all this bullshit yourself or plagiarize it?
As a math teacher, I was a damned good one, but I had a colleague who taught AP Calculus who put Jaime Escalante to the task. None of his students ever failed the AP test. As a history teacher, there was no comparison, as I taught every grade from 6th to 12th. Yes, that is conceited but I had many principals reflect that in my evaluations.
On this message board, I believe that I am the only who also served as an administrator. That experience counts a great deal in these discussions because most teachers do not have that type of career.
I am glad that you are concerned about your grandchild's education. I have a total of 4 kids in three different school systems in two states. My own children were educated in schools or districts where I taught. They didn't turn out so badly. In fact, my daughter-in-law was one of my students when she was in the 10th grade, later fell in love and married my son. She breezed through college as did my youngest daughter.
I don't have an agenda, I think you are just throwing out the biggest words in a limited vocabulary, unable to tell the truth. Your opinion means nothing to me, just as it should. You are an unqualified know-nothing.
