This document reports on a study of structural characteristics in the administrative behavior of Israeli school administrators and compares the findings with similar studies conducted in the United States, Canada, and Australia. The sample consisted of eight high school administrators, whose on-the-job behavior was observed for 5 hours per day for a total of 10 days each. Results of the study show clear similarities between the structural characteristics of Israeli school administrators and administrators in other countries in the following five respects: (1) most administrators' activities are concentrated in their offices, indicating a dominant trend of territoriality; (2) a very large proportion of administrators' time is spent in verbal contacts, whether by means of direct talks or telephone calls; (3) administrators usually relate to people on a one-to-one basis, or in "dyads"; (4) the initiation of administrative activities is almost equally divided between administrator-initiated activities and activities initiated by others; and (5) administrative activities are characterized by brevity, fragmentation, and variety. The document concludes with an in-depth discussion of the importance of utilizing the knowledge of administrative patterns of communication and participation and of the allocation of administrative time. Four tables and five figures are included. A one-page bibliography is appended. (IW)
