The Collaborative for the Continuous Improvement of Educator Effectiveness Systems

The Collaborative for the Continuous Improvement of Educator Effectiveness Systems (the “Collaborative”) is a 2-year initiative that supports six states (Arizona, Colorado, Delaware, Massachusetts, Rhode Island, and Tennessee) in investigating ways to improve educator evaluation and professional support systems. The Collaborative works to improve evaluation systems so that the process 1) assesses teacher performance in a valid and meaningful way and 2) uses that information to best support educator growth and development.

By refining and improving evaluation and professional support systems, states can build and sustain an educator workforce that is continuously improving their practices in ways that serve all students.

Partnership and Approach

The project is led through a partnership of the Center on Great Teachers & Leaders (GTL), the West Comprehensive Center, and six states. The Comprehensive Center partners convene participating states in an ongoing community of practice, which includes a series of in-person meetings and virtual cafés to facilitate connections between states and experts, as well as by pairing participating states to collaborate on shared problems of practice.

Why the Collaborative?

Since 2010, most states have adopted new educator evaluation laws and policies. States and districts have invested extensive resources in designing and implementing these systems and have seen significant system improvements. However, states continue to seek opportunities to improve systems that impact educator practices.

Rather than jettisoning or putting the brakes on this work, states participating in the Collaborative opted to stay the course, to examine lessons learned, and to use this information to strengthen educator evaluation and professional support systems to better fit the needs and priorities of local educators.

Focus: Problem of Practice and Strategies

Rooted in a continuous improvement approach, each state built on what worked within their existing system while recalibrating their models to improve educator practices and to expand the knowledge and skills of educators, both individually and collectively.

Each state involved identified a specific problem of practice along with strategies to address this problem, then relied on the Collaborative community to:

  • Hone the design and implementation of the strategy
  • Consider alignment to the larger state educator effectiveness system
  • Monitor progress toward goals and outcomes
