Observations on factor costs in public elementary & secondary Sch's, & on efforts made to measure the productivity of educ'al systems. In current dollars, the instructional expenditures per pupil per day have risen from $ 0.357 in 1929-1930, to $ 1.311 in 1957-1958. The increase for the same period in constant dollars (1949-1950 = 100), is from $0.748 to $0.915. The mean/average of all earned income in the US is used as the deflator for the salary portion of the instructional budget, under the assumption that relative changes in teachers' pay affect the calibre of staff &, hence, the output of Sch systems. Progressive Sch authorities now appear to respond to the demand for higher standards of performance by seeking to make changes in the instructional process via curriculum revision, redeployment of staff, & the use of new physical devices. Costbenefit analysis in educ is not sufficiently developed to make close judgments on the efficiency of alternative combinations of inputs, primarily because unobtrusive means of observing the teaching process are not yet available. Should teaching machines come into widespread use, however, it will be possible to link the individual instruments to a central data bank. Examination of the data obtained may allow fairly sophisticated types of systems analysis to be applied in educ. AA.
