Robert Kolker has written an excellent analysis of the anti-testing movement. The central figures are not “white suburban moms,” but a family from the Dominican Republic. Young Oscar, who loved school, loses interest when his favorite subjects and activities are replaced by test prep. The larger the test looms, the less Oscar cares about school.

Into this vivid story, Kolker weaves an overview of the opt out movement. For years, it was small but noisy. With the advent of Common Core testing, which failed 70% of students in New York State, the movement is flourishing. The more disgusted the students and parents are, the more their education is turned into endless testing, the more the movement finds new converts.
