This study investigated the purpose and role of class evaluation standards and the reason to develop these teaching standards using literature review, survey, classroom observation and teacher interviews. Based on the teachers’opinion, we also investigated who should develop teaching standards and who will benefit most from the standards. In sum, the standards for teaching evaluation should help to form (a) the guidelines for beginners, (b) the directives for specialists, (c) the principles for grasping areas for improvements, and (d) the means for communicating with other communities. In addition, teachers should take responsibility for developing teaching standards as the basis for evaluating their own work and improving their own professional learning to provide quality assurance. The development of subject specific teaching standards is not possible without active participation of teachers as well as other stakeholders in education.
