Edison Schools

Student Achievement Results

Students who attend Edison partnership schools across the country are making striking academic progress and posting significant gains in state-mandated assessments, as documented in the Eighth Annual Report on School Performance (click on the link in the box at right to view the report in its entirety). This report focuses on the academic findings at Edison partnership schools through the 2004-05 academic year.

• The percentage of students in Edison schools achieving standards has increased by an average of 3.75 percentage points in reading and 6.85 percentage points in math from the 2003-2004 school year to the 2004-2005 school year. This one-year rate of gain is approximately twice the gain rates of the states and one-and-a-half times the gain rates of the districts where these schools are located.
  

• Since the 2002-2003 school year, the percentage of students in Edison schools achieving standards of proficiency has increased on average by 10.40 percentage points in reading and 17.48 percentage points in math. Since the 2001-2002 school year the percentage of students in Edison schools achieving standards of proficiency has increased on average by 13.39 percentage points in reading, and 23.97 percentage points in math.

• Edison partnership schools are improving faster than comparable schools. Comparing the gain in z-scores of 97 Edison schools to thousands of schools with similar demographic and performance characteristics shows Edison schools with z-score differences over comparable schools of 0.095 standard deviations in reading and 0.104 standard deviations in math from the 2003-2004 school year to the 2004-2005 school year, by 0.121 standard deviations in reading and 0.242 standard deviations in math from the 2002-2003 school year to the 2004-2005 school year, and by 0.220 standard deviations in reading and 0.439 standard deviations in math from the 2001-2002 school year to the 2004-2005 school year. Researchers generally view differences of 0.20 standard deviation or higher as important.
  

• For the tenth consecutive year, parents are overwhelmingly satisfied with their Edison partnership schools. In an independent survey 86 percent of parents who responded to surveys rate their school an "A" or a "B," with A being the most popular grade. According to an annual Gallup poll, in a similar survey of public school parents nationwide, only 69 percent of parents rated their child's school an "A" or "B."
