Mind the Gap [LINK]

Whenever you hear of a "gap," it generally means the underlying trend is fine in absolute terms.

Based on a recent Globe report on outgoing Boston school superintendent Thomas Payzant, Lisa Guisbond cites the increased achievement gap between poor minority and affluent white students under his tenure as evidence of the failure of MCAS. But the same report noted that while Boston's dropout rate remained flat, SAT scores and the college enrollment rate both increased. Boston's parents, especially those who understand mathematics, should be more interested in whether MCAS might improve their children's performance than in whether it might benefit other children more.
