Mazany says staff and teacher morale was extremely low when he took over from former schools CEO Ron Huberman and that the district has been paying attention to the wrong things.
"The focus has shifted to an emphasis on testing. In essence, what we have done, we have traded off quality teaching in exchange for the tyranny testing," said Mazany told ABC7.
To change that, Mazany is drafting a new education plan that he believes will get the system back on track.
That plan will go to Mayor-elect Rahm Emanuel who takes office in May. It's up to Emanuel to pick a permanent schools chief.
Mazany firmly says he isn't a candidate for the job, but when asked if he'd accept the position if asked he isn't saying no.
He says his focus right now has to be on laying the groundwork for a solid school system next year.
