摘要：The aim of this study was to develop and validate an instrument of classroom climate based on the instrument developed in Australia. The instrument consisted of two forms, the actual and preferred forms, to measure aspects of the actual and preferred classroom climate. The study involved 1126 grade V and VI elementary school students in Padang, West Sumatera. Data were analysed by applying factor analysis, Cronbach Alpha and discriminant validity. The result of the study demontrsted that the empirical evidence supported the items grouped into scales. The internal consistency of the instrument was higher than the previous version. Each item of the instrument does not overlap with the others. So, the instrument can be implemented to measur classroom climate. It is suggested to validate the instrument for junior high school students.
