Psychometrically sound and practical measures of school value, teacher autonomy, and teacher motivation were developed. Further, this study examined relationships among school value, teacher autonomy, and teacher motivation and compared the differences between elementary and secondary school teachers in those variables. Findings showed that those measures are reliable and valid. Also, elementary school teachers scored higher in those three variables than secondary school teachers. Particularly, school value and teacher autonomy were significant predictors of teacher motivation. The implication for school organization is to enhance positive school value and provide teachers with more autonomy, which will encourage teacher motivation.
