The purpose of this study was to gather data and test the hypothesis that the number of constant dollars expended for educational supervision by Louisiana public school systems increased during the decade from 1963 to 1974. To facilitate comparison of expenditures from different years, all financial data are expressed in terms of "constant dollars" computed on the base year 1967. Analysis of the data show that the number of supervisors increased 139.9 percent from 1963 to 1974, compared to a 6.8 percent increase in the number of students, a 30.5 percent increase in teachers, and a .1 percent increase in principals. In terms of constant dollars, expenditures for educational supervision increased approximately 700 percent, while total expenditures per student increased 131 percent and average teachers' salaries rose approximately 9 percent. The data also indicate a recent downward trend in total educational expenditures; in constant dollars, expenditures per student declined from a peak of $644 in 1971-72 to $616 in 1973-74. (Author/JG)
