Percentages of fee increases are included. Section II shows full-time salaries for beginning and experienced teachers, with the same geographic breakdown as in section I. This section also shows the range of highest, median, and lowest salaries for the year, as well as the percentage of increase in medians since 1978-79. Section III concentrates on salary ranges for full-time administrative officers for size and type (day and boarding) of school.
