The Georgia Department of Education (GaDOE) conducted an
extensive process, working with multiple educator advisory groups and technical
advisors, to select and implement its student growth model. As part of this
process, GaDOE contracted with three leading, external researchers to begin the
process of validating the model and its use in the state’s educator
effectiveness system. We are pleased to release this set of five studies and
overview that contribute to a technical evaluation of the Georgia Student
Growth Model.
