Student Growth for Educator Evaluation
Legislation requires that 25 percent of teacher and administrator evaluations be based on "student growth and assessment data” during the 2016-2017 and 2017-2018 school years. Furthermore, beginning in 2018-2019, the law requires that 40 percent of half of teacher and administrator evaluations be based on "student growth and assessment data”, with half of the growth component of evaluations comprised of state assessment data for tested grades and subjects. Schools, districts, ISDs, and PSAs using educator evaluation as a continual improvement process are encouraged to define student growth and assessment data as the academic performance of a student or group of students over two or more time points (Castellano and Ho, 2013). Below, you will find resources that will help you as you determine the best way to use state and local data in evaluations that are fair to educators and most likely to lead to improved teacher performance.
Approaches to Measuring Student Growth
- Student Growth Percentiles (SGPs)
Student Growth Percentiles (SGPs) represent one powerful way to quantify the learning of individual students over one or more years. Conceptually, SGPs communicate the degree to which a student has learned in a particular domain, compared to a group of academic peers who had a comparable score on the previous test (or multiple previous tests) in that subject.
- Student Learning Objectives (SLOs)
Student Learning Objectives (SLOs) are measurable, long-term, academic goals, informed by available data, that a teacher or teacher team sets at the beginning of the year for all students.

- A Practitioner's Guide to Growth Models
A Practitioner's Guide to Growth Models clearly describes different ways to calculate student academic growth and to make judgments about the adequacy of that growth. It helps to clarify the questions that each model answers best as well as the limitations of each model.
