I didn't mind being a "martyr" and staying after 3, or taking work home until school "reform" kicked in.
I was always willing in the 80s and 90s to spend my "own" time making prep for what I was going to do *in class* the next day.
But now they just want ( DEMAND!) scads of inane "data" establishing student progress. The instruments they are using to assess severely-handicapped special ed kids are so utterly asinine that they have to be seen to be believed. They were all hastily devised in the wake of RTTP or just carried over from gen ed. (In which case, they're invalid. The kids are in self-contained sped for a reason. Jeeeeesus.)
According to the Obama administration, everybody has to have data. So the bureaucracy produces data. Doesn't matter what the quality of the data is... just so long as it's data. And LOTS of it. You can't have too much data. Even if no one's being taught properly as a consequence.
Data.
Work of this kind comprised 9/10 of the clerical work I was doing in the last two years before I retired. I imagine a comparable corruption of education is going on in gen ed.
