North Carolina has embarked on an ambitious effort to improve its public schools. Career-and college-ready standards, high-quality assessments, and advanced technology are all part of this effort, and each plays an important role. No part of students' educational experience matters more than the teachers who facilitate their learning. North Carolina's effective educators are those who meets the expectations of the state's Educator Evaluation System. Trained administrators determine to what extent teachers demonstrate leadership, meet diverse students' needs, master content, facilitate learning, and reflect on their craft. The system is built around six standards for teachers: (1) Demonstrate Leadership; (2) Establish Environment; (3) Know Content; (4) Facilitate Learning; (5) Reflect on Practice; and (6) Contribute to Academic Success. The sixth standard focuses on the impact that teachers have on student growth. This document provides a guide for using student growth data to evaluate North Carolina's teachers. The first section summarizes recent changes to the North Carolina Education Evaluation System, including the addition of a new evaluation standard in which growth data inform a teacher's rating. The second section details the various ways in which growth will be calculated. The remaining sections outline which assessment data will be used to measure student progress, how student growth will be calculated using the assessment results, and which data will be included in individual teacher growth values. The guide also outlines local flexibility for measuring student growth as part of the educator effectiveness model.
