Introduction to the Insights

We are in the midst of a massive shift toward transforming today’s teacher effectiveness systems. The old systems - based on institutional metrics of seniority, principal observation and degrees or certifications earned – historically led to only two possible ratings of effectiveness: satisfactory or unsatisfactory. How possibly can we acknowledge and act on differences in teacher effectiveness when nearly all teachers – 99 percent in many districts – earn the “satisfactory” rating? How possibly can teachers reach their full potential when so little information is provided to help them grow and build on their strengths?
