Chubb and Clark Examine State Achievement Gap


• Dr. Matthew Ladner

Some states are serious, others Shirley when it comes to education reform.

John Chubb and Constance Clark have a very interesting new study out from Education Sector called The New State Achievement Gap: How NCLB Waivers Could Make it Worse or Better.

Chubb and Clark examine NAEP data and find that states are diverging into leaders and laggards. In the relative blink of an eye between 2003 and 2011 they found the gap between the performance of students in the best and worst performing states grew to 60 percent of the size of the White-Black achievement gap on the combined NAEP exams (4th/8th reading and math).

Ladner: New State Achievement Gap in Context

Note that part of what has happened here is that the White-Black gap shrank a bit. Note, however, that it is still sickeningly large. Keep in mind that 10 points roughly equates to a grade level worth of average progress on NAEP- so 105 points across four tests is quite disgusting. The state achievement gap meanwhile grew steadily.

Chubb and Clark’s paper would have benefited from examination of the gory details about how some states are playing fast and loose regarding NAEP inclusion standards for special needs and English language learners- especially in the case of Maryland and Kentucky. These details do not however take away the broad point- some states are improving and some are getting left behind.

Ladner: State Comparisons

The study gets even more interesting as the authors compare the NCLB waivers, accountability systems and standards choices of states with strong and weak NAEP gain performances. Included among these is a comparison between Florida and South Carolina. The referee needs to step in and wrap up Maryland before he pummels West Virginia to death. “Self-reflection” for teacher evaluation Mountaineers? Surely you can’t be serious…

In a not-quite-elliptical fashion, Chubb and Clark note a clustering of states with a recent history of weak NAEP gains with unconvincing NCLB waiver promises and the Smarter Balanced Assessment Consortium. I’m shocked…

Chubb and Clark have turned in a very interesting and nuanced examination of scores and policy.
