This report, prepared from data supplied by Educational Research Service, Inc., deals specifically with 1975-76 comparative data about salaries paid to principals and assistant principals in approximately 700 public school districts. Section 1 compares the lowest and highest 1975-76 salaries paid to principals and assistant principals, using school district enrollment stratum as a comparative factor. Section 2 discloses a similar comparison of salaries paid, using per-pupil-expenditure in the school system as a factor for comparison. Section 3 contains a trend analysis of salaries paid to a selected group of administrators using data from 1974-75 and 1975-76. Caution should be used when drawing inferences from survey data because of the sampling variance associated with studies of this type. (Author)
