Kirabo Jackson, an economist at Northwestern University, uses data to demonstrate what most of us know. Teachers have a big impact on student behavior. Their impact on behavior matters far more than their impact on test scores.

Get this: VAM was rewarding the wrong teachers. Not the ones who changed students’ lives, but the ones that raised scores.

Get this: Race to the Top favored the latter (the test score raisers) and fired the ones who made the biggest difference.

Get this: Schools were closed based on the wrong criteria.

Get this: Federal law prioritizes the wrong things.
