Founded in 1992, Edison partners with school districts and charter boards to raise student achievement through its research-based school design, aligned assessment systems, interactive professional development, integrated use of technology and other proven program features. Edison students are achieving annual academic gains well above national norms. Edison Schools now serves more than 132,000 public school students in over 20 states through four different business channels: (1) the management of schools for school districts, (2) charter schools, (3) summer and after-school programs, and (4) achievement management solutions for school systems. The company operates 130 charter and district schools. Between 1992 and 1995 and in on-going efforts, Edison’s team of leading educators and scholars has conducted intensive research to develop its school design and support systems. Edison opened its first four schools in August 1995, and has grown rapidly in every subsequent year. How does Edison operate? How are Edison schools doing?
