EVAAS value-added modeling is based on the philosophy that all kids count and that schools should not be held responsible for the things they cannot change, like a child’s socio-economic status, and that schools should be responsible for the things they can change, like a child’s growth during a year of schooling. We believe that: --All kids count --All kids can learn --All kids deserve opportunities to make appropriate academic progress every year --Educators can manage their effectiveness to improve student opportunities. More specifically, value-added does this by following the same student over time and utilizing all available scores from each student’s informational array.
