It is one of the curiosities of our time that reformers point to D.C. as one of their triumphs, based on the gain of a few points in test scores on NAEP and rising graduation rates.

D.C. remains one of the lowest performing districts in the nation. And on those same NAEP tests that gladden the hearts of reformers, the D.C. schools have the biggest achievement gaps between blacks and whites and between Hispanics and whites of any urban district in the nation.

D.C. is not a model for the nation.

Reformers pointed to impressive graduation rates as evidence for the D.C. Miracle.

Now we know that the D.C. graduation rates were phony, and that about a third of graduates received diplomas despite absences and lacking credits.
