Since early in this century educators have been proposing staffing formulas they believe will facilitate educational quality. The resulting guidelines represent a wide range of recommendations--from the possible to the utopian. School boards, teachers' groups, administrators, consultants, and taxpayers thus have a range of choices among the recommendations presented herein. In any situation, however, three factors will affect their choices of guidelines: the needs of the pupils, the availability of qualified personnel, and the funds available. This report contains no concise summary of low, high, and/or typical recommendations for each position. Several factors make it impossible to compare accurately and fairly the recommendations within the 32 tables--various measures are used in the ratios; the titles used to group information may not represent comparable responsibilities; because it is not always known whether a given ratio represents the author's recommendation for minimum, adequate, or optimum staffing, dissimilar ratios might be compared; and recommended ratios are influenced by the supply of educational personnel and the prevailing practices. A bibliography is included. (Author/IRT)
