State Model Evaluation System for Principals/Assistant Principals

Principal Quality Standards

To support districts in their implementation of Senate Bill 10-191, CDE created a State Model Evaluation System for principals that aligns with State Board of Education rules. Under the model system, principals are evaluated on seven Quality Standards (download the Principal Quality Standards overview) :

  • Half of the evaluation will be based on the six professional practice Quality Standards: strategic leadership, instructional leadership, school cultural and equity leadership, human resource leadership, managerial leadership and external development leadership. The Quality Standards can be measured using the state-developed rubric that identifies the practices necessary to achieve the standards.
  • The other half of a principal’s evaluation will be based on Measures of Student Learning which measures the academic growth of the students in their school. Principals must have a team attribution student growth score and student growth scores that are aligned to their teachers.

Measuring the 50% Student Learning

The "Measures of Student Learning Guidance" is intended to give districts and BOCES a starting point for determining the 50 percent measures of student learning portion of teacher and principal evaluations. CDE is using pilot experience and overall feedback to improve this guidance over time. To access, visit the Measures of Student Learning Guidance website.

Determining a Final Educator Effectiveness Rating

S.B. 10-191 requires that 50 percent of an educator’s evaluation be based on professional practices and 50 percent be based on multiple measures of student learning. Educators will earn a professional practice score based on the rubric and a measures of student learning score based on multiple measures. The professional practices score and the measures of student learning scores are combined to determine an overall effectiveness rating of Ineffective, Partially Effective, Effective or Highly Effective.There are several approaches and methods for combining these measures to arrive at a final effectiveness rating for educators.
