The problem was to compare regional high schools including grades 9 to 12, small high schools having the same grades, and other high schools having per-pupil cost comparable to regional high schools in terms of the following criteria: (a) per-pupil expenditures; (b) pupil-teacher ratios; (c) number of different preparations per teacher; (d) scope of course offerings in each major curricular field; (e) ages of teachers; (f) teacher salaries; (g) educational experience of teachers; (h) availability of library and guidance personnel; and (i) educational preparation (degree level) of teachers. Results indicated that per-pupil cost in regional high schools is approximately $100 more than the per-pupil expenditure in small high schools; average pupil-teacher ratios in the 3 types of high schools do not vary greatly; teachers in small high schools average more different teaching preparation than their counterparts in regional and nonregional high schools; course offerings are fewer in the small high school; ages of teachers in the 3 types of high schools are roughly comparable but the salaries are smaller in the small high school; teachers in regional and selected nonregional high schools have the highest level of educational attainment; and guidance counselors and librarians are less likely to be available to students in small high schools.
