The current study aims at exploring the common means that may improve organizational effectiveness by focusing on two main facets of organizational qualities: teacher commitment and job satisfaction. Data were collected from 841 randomly sampled teachers employed in 118 elementary schools in Israel. Multiple regression analyses revealed that the single variable that predicted both types of commitment (organizational and professional) and both types of satisfaction (intrinsic and extrinsic) was teachers’ perceptions of the fit between one’s job demands and abilities. The second most influential predictor was principals’ interaction with the teachers.
