Every school must be able to answer this question: How do we assure that we have a great faculty to deliver the mission with excellence, and ultimately increase student performance, satisfaction, and enthusiasm? While the answer, “with an effective teacher evaluation process,” is a common response, a significant problem arises—teacher evaluation processes are completely ineffective. Large-scale research has found schools do not accurately discriminate between effective and ineffective teachers,1 nor do they drive professional development or improve student outcomes.2 In our travels, ISM Consultants have found few schools that serve as exemplars in this area. Your school likely struggles to establish an effective, consistent, and culture-enriching evaluation process.
