Edison Scores

With about one-half of Edison's 2001-2002 test scores so far recorded, the average annual improvement rate thus far is approximately 6.5 points on 100- point scale.

According to John Chubb the system-wide gains recorded thus far include dramatic improvement rates in Washington D.C. (average gains of seven, 10 and 17 percentiles in three schools); Chicago (an average gain of 14 percentiles in a K-12 charter school); Baltimore (average gains of 10, 16 and 24 percentiles in three schools); and Dallas (average gains of seven percentage points in seven schools).

[Update] The Atlantic-Journal Constitution also runs a somewhat favorable article about Edison and local experiences with the company.
