In 2013, 25 states required that student achievement is a big or the biggest part of teacher evaluations. Twenty-seven states required teacher evaluations be based on a variety of student assessments and work samples and 44 states required classroom observations to be put into teacher evaluations. It describes a variety of methods, such as observations, student assessments, student work samples and examples of teacher work, that education leaders use to determine the effectiveness of a K-12 educator. Educator effectiveness is a method used in the K-12 school system that uses multiple measures of assessments including classroom observations, student work samples, assessment scores and teacher artifacts, to determine the impact a particular teacher has on student's learning outcomes.
