This study assessed student performance in 40 schools that were already implementing the EIC approach. It was completed by Lieberman and Hoody in partnership with 12 State Departments of Education. The data came from site visits to all 40 schools and inclued four different teacher surveys, interviews with more than 400 students and 250 teachers and administrators. Moreover, in 14 of the subject schools, the EIC students were compared with students from the same schools who were in traditional classrooms looking at on standardized test scores, grade point averages, attendance, student attitude measures, and records of disciplinary actions.
The results: higher scores on standardized measures of academic achievement in reading, writing, math, science, and social studies; reduced discipline and classroom management problems; increased engagement and enthusiasm for learning; and greater pride and ownership in their accomplishments.
