This paper discusses some of the questions and issues implied in the California Serrano vs Priest decision. Note is made that if courts adopt a strict definition of uniformity as a criterion of equality, States may have to abandon local taxes and establish systems of full State funding plus federal aids. On the other hand, if courts adopt dynamic criteria of equalization, with some tolerance between the highest and lowest expenditure per unit of comparable need, States might, with some reform, retain local-State-federal participation. The author indicates that federal general aid to education will become increasingly important in the future. (JF)
