The rapid expansion of many branches of education in most of the 22-member countries of the Organisation for Economic Cooperation and Development has rarely been accurately forecast. The most important overall objective of educational policy during the decade has been (1) educational opportunity for all and (2) equalization of educational opportunity. This expansion appears to stem from the so-called social demand approach to educational planning, which claims that places should be provided by the public in all branches of education for all children who seek them and who have proved that they have the requisite abilities to benefit from courses in the particular branch of education in which a place is sought. Although it was assumed that rapid expansion of educational opportunity for all would accrue from this approach, the policy actually contains an antiegalitarian bias in favor of middle class children. Both the inputs (resources) and the outputs of the educational systems have increased enormously during the past decade despite partially conflicting manpower and efficiency considerations. A radically new approach to the problem of relating forecasting, planning, and policymaking appears needed for the educational systems in question.
