Student Growth

Student Growth Percentiles

A student growth percentile (SGP) describes a student's growth compared to other students with similar prior test scores (their academic peers).

Comprehensive information about SGPs, including FAQs and a video introduction, is available on the Student Growth Percentiles web page.

Student growth is the change in student achievement between two points in time (RCW 28A.405.100). Student growth refers to the learning progress made by students through instructional experiences.

The student growth process includes: setting goals for students, planning instruction and assessment, and reflecting on student progress. Student growth is a substantial factor in evaluating educators.

Student growth is the change in student achievement between two points in time. Student growth data must be a substantial factor in evaluating the summative performance for at least three of the evaluation criteria for both teachers and principals. 

For teachers, there are five components of student growth embedded across criteria three, six, and eight. They are the same state components for each of the approved instructional frameworks. 

  • SG 3.1-Establish Student Growth Goals
    Refers to individual or subgroups of students (achievement/opportunity gap)
  • SG 3.2-Achievement of Student Growth Goals
    Refers to individual or subgroups of students (achievement/opportunity gap)
  • SG 6.1-Establish Student Growth Goals using Multiple Student Data Elements
    Refers to the whole class based on appropriate standards and aligned to school goals
  • SG 6.2-Achievement of Student Growth Goals
    Refers to the whole class based on appropriate standards and aligned to school goals
  • SG 8.1-Establish Team Student Growth Goals
    Refers to the teacher as part of a grade-level, content area, or other school or district team

For school leaders, there are three components of student growth embedded in criteria three, five, and eight. They are also identical across both of the approved leadership frameworks. The components are:

  • SG 3-Provides evidence of student growth that results from the school improvement planning process.
  • SG 5-Provides evidence of student growth of selected teachers.
  • SG 8-Provides evidence of growth in student learning.

Student Growth Rubrics

More than one measure of student growth must be used in scoring the student growth rubrics and it must be determined by an analysis of evidence.

More than one measure of student growth must be used in scoring the student growth rubrics and it must be determined by an analysis of evidence.

Student Growth Impact Rating

Upon completion of the overall summative scoring process, the evaluator will combine only the student growth rubric scores to assess the certificated classroom teacher, principal or assistant principal's student growth impact rating. The student growth impact rating will be determined by the superintendent of public instruction's student impact rating scoring band.

A student growth score of "1" in any of the rubric rows will result in an overall low student growth impact rating. Evaluators must analyze the student growth score in light of the overall summative score and determine outcomes.

Case Stories

The Center for Strengthening the Teaching Profession, in partnership with OSPI convened a group of National Board Certified Teachers to discuss how these teachers are using student growth in their classroom. If you're looking for one of the original case stories, contact tpep@k12.wa.us.
