This document describes the model used by the New York State Education Department (NYSED) to measure student growth for institutional accountability in New York State for the 2016/17 school year. In 2016/17, growth models were implemented for institutional accountability in Grades 4-8 ELA and mathematics. All models are based on assessing each student's change in performance between 2015/16 (and prior years) and 2016/17 on State assessments compared with students who have similar prior performance. Revisions to the State-provided growth model will be considered in future years. The results presented in this report are based on 2016/17 and prior school years' data, with some comparison to prior-year results. This technical report contains four main sections: (1) Data -- Description of the data used to implement the student growth model, including data processing rules and relevant issues that arose during processing; (2) Model -- Description of the unadjusted statistical model; (3) Reporting -- Description of reporting metrics; and (4) Results -- Overview of key model results aimed at providing information on model quality and characteristics.
