This study focuses on the construction and validation of a Teacher Performance Scale for Higher Secondary Teachers (TPSHSS), designed to assess teachers’ in depth knowledge about the subject, and their professional and relational competence. The research employed a random sampling technique. Initially, a thorough literature review and group discussions with Psychologists, teachers and experts in the field of education were held in order to frame the relevant statements. Initially 38 statements were made. The scale was administered to a sample of 100 higher secondary teachers across different educational institutions of Shopian and Pulwama. The investigator has used a normative survey method for the study. Item analysis was adopted for the final selection of items. The total scores were calculated separately and they were arranged in the descending order. The top 25% and the bottom 25% of scores alone were taken into account. The difference in means of the high and low groups for each item was tested for significance by computing the t- ratios. Items with ‘t’ value of 1.96 and above were selected for the final tool. Thus 30 statements were selected and 8 have been eliminated. This scale provides educators, counselors, and researchers with a psychometrically sound tool for assessing and enhancing teacher performance among higher secondary teachers.
