This study explains assessments of fair pay for public school administrators in terms of some individual, job-related, and contextual variables, and it tests Jaques' hypothesis that time-span of discretion is the unconscious measure of level of work in bureaucracies. Data were gathered primarily through telephone interviews with superior/subordinate administrative pairs. The conclusion was that Jaques' concept appears to be too narrow to account for the work of public school administrators. Based on the findings, a multidimensional conception of level of work is proposed for public school administration. (Author/TE)
