As part of its Race to the Top (RTT) grant, the Office of the State Superintendent of Education (OSSE) in Washington, DC, developed a school-level model to measure growth in student achievement over time. Different education agencies in the District of Columbia are using the data from this model for different purposes, including informational reporting and as one component of a school-level accountability system.
The model used by OSSE is a “student growth percentile” (SGP) or “median growth percentile” (MGP) model and includes only test scores to measure growth (i.e., with no adjustments for student or school-level contextual variables). A detailed description of the model can be found in the attached report.
