Teacher Evaluation: Overview

Due to the cancelation of the New Jersey Student Learning Assessment (NJSLA) in school year 2020-2021 median Student Growth Percentiles (mSGP) will not be included the summative score of any teacher, Principal, Assistant Principal (AP) or Vice Principal (VP). It is anticipated that NJSLA testing will resume in the 2021-2022 school year and thus, mSGPs will once again be included in the summative score of all eligible teachers, Principals, APs and VPs for the 2022-2023 school year.

SGP is a measure of how much a student improves his or her state test performance from one year to the next compared to students across the state with a similar score history.

Teacher evaluation consists of two primary components:

  • Teacher Practice - measured primarily by classroom observations; and
  • Student Achievement  - measured by Student Growth Objectives, and, additionally, Student Growth Percentiles for teachers of students who take state tests.
