The Studies of Implementation project is a 3-year longitudinal investigation of planned educational change. The research focuses on the process by which an innovation becomes a pattern of individualized schooling. This study identifies those conditions that promote or retard change and relates them to the modifications they foster. It reports on the results of a study of the relationship between the perceived level of participation and the level of job satisfaction of secondary school teachers. The study: (1) tested the Alutto-Belasco argument that an individuals' desire for increased participation mediates this relationship; (2) tested the validity of the commonly used "summated" scoring procedure for measuring decisional participation; and (3) investigated the utility of defining decisional participation in terms of frequency and extent of involvement. The study follows the direction set by Alutto and Belasco (1972), but extends their work by assessing the practicality of considering decisional participation as bidimensional, consisting of the frequency (rate) and extent (quality) of subordinate involvement.
