Developing the “Teacher Perceived Performance Scale” Assessing the Secondary School Teachers’ Perceived Performance in General Teacher Professional Competencies

This research aims to develop a valid and reliable tool to assess the perceived performance of secondary school teachers in general competency areas of the teaching profession. For this aim, a 66-item 5-point Likert-type draft scale form was developed by arranging the general competency indicators of the teaching profession. First, the form was revised after taking expert opinions for content and face validity and administered to 310 secondary school teachers working in the central district of Çanakkale. Exploratory factor analysis was carried out with the data gathered. Then, to verify the structure obtained, the form was administered to 119 secondary school teachers working in Çanakkale districts, and a confirmatory factor analysis was conducted. The structure of the scale consisting of 23 items under five factors was confirmed (?2/df = 1.68, root mean square error of approximation = 0.08, root mean square residual = 0.04, comparative fit index = 0.94, non-formed fit index = 0.94). Finally, the internal consistency coefficient of the whole scale was calculated as 0.90.
