Accurate data related to current salaries are essential in developing and maintaining adequate compensation for administrative personnel. This is the first in a series of comprehensive ERS national studies of salaries and fringe benefits for administrative and supervisory personnel in public schools. This report gives precise information for school districts responding to a national survey of a stratified random sample of large, medium, and small school systems. The major part of the report consists of a system-by-system listing of the 562 districts that furnished usable salary schedule information. The listing gives each system's minimum and maximum scheduled salaries for associate and/or deputy superintendents, assistant superintendents, and certain other central-office positions; and scheduled minimum and maximum salaries for supervising and assistant principals. Salaries shown for superintendents are salaries actually being paid since the salaries of superintendents are usually based on an individual contract with the school board. The listing also includes detailed information regarding the scheduling of salaries for principals (e.g., differentials for days on duty, academic preparation levels, and size of school to which assigned). Also, methods of structuring schedules based on their relationship, or lack of relationship, to the schedules for teachers are shown in the listing. Summary tables are included that show mean, median, and ranges of minimum salaries scheduled and maximum salaries scheduled in reporting systems. (Author)
