Revisiting the Effect of the Kalamazoo Promise on Achievement
MetadataShow full item record
Many people believe that the Kalamazoo Promise raised the achievement of Kalamazoo Public Schools students. Previous research has shown small increases in standardized test scores relative to comparison districts, but these results were not statistically significant. The author analyzed aggregate test score data from 2005-2013 to study changes between Kalamazoo and five comparison districts. The author found that Kalamazoo made statistically significant gains relative to their comparisons in every demographic group for nearly every subject. These gains were of similar magnitude across ages, genders, and racial categories. However, economically disadvantaged students had lower gains than non-economically disadvantaged students, although they still made positive gains relative to comparison districts.
