Edison gains

Test scores are increasing at Edison schools, the for-profit reports. The average increase in students achieving standards was 7.4 points from 2002-03 to 2003-04, about double the gain rates of local schools, Edison says. Schools with a mostly black enrollment “average one-year gains of 9.2 percentage points and two-year gains of 17.8 percentage points . . . two to three times the gain rates of the districts and states in which these schools are located.”

An independent survey found 84 percent of parents give their Edison school and “A” or “B” grade.
