Chester recommending 25% growth

At tomorrow's meeting, the Massachusetts Board of Education will take up the question of how to weigh student growth in district measures. In his memo to the Board, Commissioner Chester is recommending a measure of 75% achievement (aka, plain old MCAS scores) and 25% growth.
He also comments:

I do not accept the proposition that some urban districts must always rank below low-performing suburban or rural districts.

Thank you, Commissioner. Neither do we.

This measure impacts which districts are considered the "lowest-performing" districts, as well as in which ones charter schools are allowed to open or expand.
I will not, unfortunately, be able to be at tomorrow's meeting. Hope James Vaznis is going to tweet!
