How would you articulate the difference between growth and proficiency measures?
Reason for asking is to have an intelligent answer when Anchorage School District begs for more money.
Just a theory... teachers are not allowed discretion in assessing and documenting growth in learning because a gaggle of teachers operating independently of each other are unlikely to produce the statistical result necessary to justify purchasing expensive solutions to insulate senior management (and who knows, maybe senior union officials) from the consequences of conflating education with education industry.
Not sure the Department of Education was the best thing that ever befell America's schools...
