Student Growth Measures for Teachers

A major percentage of each teacher's evaluation comes from how much their students learn throughout the year. Student growth measures are a method for determining how much academic progress students are making by measuring growth between two points in time. 

The challenge for measuring student growth is that not all teachers can use the same assessment. For the purpose of teacher and principal evaluations, there are three ways to measure student growth.

Types of Student Growth Measures

  1. Value-Added
    Ohio’s state tests provide value-added data, which research supports as a valid student growth measure. But because state tests are new, by statute, teachers and principals will not use value-added ratings from state tests for 2014-2015 and 2015-2016 school years as part of their evaluations or when making decisions regarding dismissal, retention, tenure or compensation – unless districts and educators enter into a memorandum of understanding to do so. 
  2. Approved Vendor Assessments
    If Value-Added data is not available, districts or schools can use other assessments provided by national testing vendors and approved for use in Ohio.
  3. Locally Determined Measures
    For subjects where traditional assessments are not an option (such as art or music) districts or schools should establish a process to create locally determined measures, including student learning objectives, to measure student progress.
    Types of locally determined measures include:

State law, Ohio House Bill 64, made adjustments to the Ohio Teacher Evaluation System for the 2015-2016 school year and beyond. Districts will choose between the original teacher evaluation framework (based on teacher performance rating and student growth rating, each at 50 percent) – and the alternative teacher evaluation framework. The alternative framework includes teacher performance at 50 percent, student growth at 35 percent and an additional measure as 15 percent of the evaluation.

The percentages for student growth measure components in both the original and alternative framework are pictured below. These diagrams are from the large graphic charts for the complete original and alternative frameworks that are posted here.
