Legislation requires that a portion of teacher and administrator evaluations be based on "student growth and assessment data." Furthermore, beginning in 2018-2019, the law requires that half of the growth component of evaluations come from state assessment data, when available. 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.
