Past researchers have claimed that it is possible to over-involve individuals in decision-making and that this saturation may result in a decrease in job satisfaction. This paper presents a synthesis of three studies that covered the kindergarten through 12-th grade spectrum and tested the curvilinear relationship between teacher involvement in decision-making and job satisfaction. The research found that a significant relationship existed between respondents' decision condition and their level of job satisfaction. The results also indicate that the point of saturation has not been reached. From the responses in these studies it is reasonable to assume that administrators have considerable latitude in which to increase teacher involvement in decision-making before diminishing job satisfaction. The paper includes an extensive reference list, two tables, and one illustrative figure. (Author/MD)
