According to Schacter, (2008) the concept of Kalamazoo Teacher Accountability aroused hostility among 93% of educators participating in the study because the research established a defensive attitude among educators, largely due to the existing performance measurement system for students. The research development path to date has then evolved to provide information on the personal attributes, knowledge, skills, characteristics, teaching methods and behaviors that distinguish high-level educators from mediocre ones. There are teachers of the highest caliber and it can be developed by focusing on efforts to develop and acquire effective teaching performance. It is necessary to establish a knowledge base and continuously update it to promote the development of educator quality. Effective teaching exists, but it seems that it needs to be defined and measured in relation to student outcomes. Initially, the issue of pretests and posttests made sense to teachers as a means of making instructional decisions. Teachers typically use a pre-test to ascertain children's current knowledge base. Unfortunately, teachers have not been provided with the appropriate basic skills to help them decide what to teach and in what depth. As in the case of the Kalamazoo study, teachers may have the idea that they are being evaluated, but they do not understand the totality of their responsibility, which extends beyond their personal immediacy to generations of students and future educators. Therefore, the effectiveness of the pretest needs to be carefully examined. Students must understand the purpose of the pre-test, that scores do not count towards their grade, and know that the outcome of the test is not to achieve high performance in a competitive context… middle of the paper… .5) .
