Development and Validation of Teachers' Job Performance Scale

The present article describes the process of development of an indigenous scale to measure the job performance of school teachers. The development and validation of this scale was carried out in different steps by using independent samples. The Teachers' Job Performance Scale (IJPS) comprises 25 items with 5-point rating scale. The teachers' performance was evaluated by their students. A sample of 180 students of secondary schools was taken to evaluate their 60 teachers. Each teacher was rated by three students. The factor analysis of items revealed four factors i.e., teaching skills, management skills, discipline and regularity, and interpersonal skills as the determinants of teachers' job performance. The psychometric properties of TJPS revealed that it has alpha coefficient of .94 for the entire scale and has sufficient internal consistency, and inter­ rater reliability. The empirical evaluation also shows sufficient validity of scale.
