This paper comprises a compilation of information on the positional mobility and migration of superintendents and superintendent-principals within the Oregon public school system. The author reports on studies of 43 superintendents who left their positions in one year. He analyzes (1) the turnover rate and the school system size, (2) the mobility patterns, (3) the nature of the subsequent offices to which the superintendents moved, and (4) the migration between superintendencies by eight superintendents who moved to other district superintendencies. The author notes that the superintendency in a small district is readily interchangeable with the principalship of or a subordinate central office position in a larger school district. (JF)
