This report is an early release of a measurement instrument used in a longitudinal project Management Implications of Team Teaching (MITT), and is taken from a larger, technical Project MITT report, "Governance and Task Interdependence in Schools: First Report of a Longitudinal Study." The report describes the development of a 24-item questionnaire scale assessing the sense of work autonomy among classroom teachers. The conceptualization of the domain and the procedures used in scale development are described. Data regarding scale reliability and score distributions for a population of teachers as well as the results of factor analyses undertaken to examine the dimensionality of the scale are included.
