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
    If available, teachers must include Value-Added data in the student growth measure.  If allowed by law, the local education agency may also use local student growth measures. 
  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:

Due to changes in Sub. Ohio House Bill 362, school districts have the option to make a change in their  teacher evaluation framework beginning in the 2014-2015 school year. This change in law allows districts to choose between the current (original) teacher evaluation structure (based on teacher performance rating and student growth rating, each at 50 percent) – and a new alternative teacher evaluation structure. The alternative framework includes student growth and teacher performance at 42.5 percent each, as well as 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.
