Raising Student Achievement
Many districts are facing the difficult challenge of improving student achievement to meet increasingly rigorous standards. Over the past ten years Edison Schools has invested considerable time and focus on research and development to create comprehensive systems and a world-class school design that help our partner districts drive student achievement. In more than one hundred communities across the country, our partners have proven that this system works.
- 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.

- Historically underperforming partnership schools have dramatically raised achievement over time in comparison to schools with similar levels of economic disadvantage and ethnicity. 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 0.220 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.
