There is scarcely a State in the Union today which is not confronted with many difficult problems due to a lack of adequate school revenues. The increasing numbers demanding education and the increasing demands placed upon the schools have led to enormous increases in expenditures. There is every reason for believing that these expenditures will continue to increase rather than to decrease. As a result of intensive study these authors are convinced of the soundness of the following conclusions: (1) That educational inequalities, flagrant and ominous for the future of our Nation, exist within the borders of almost every State; and (2) that these educational inequalities can not be remedied until the State assumes the responsibility of equalizing school revenues and school burdens. In nearly every State increasing State school funds must be provided; but the provision of larger funds will by no means solve the problem. Equally important is the abolition of the antiquated, unscientific, and unjust methods of apportioning State aid which are still employed in the majority of our States. A study prepared a number of years ago ("State Policies in Public-School Finance," Bureau of Education Bulletin No. 6, 1922) called attention to the fact that increased State revenues must in the future undoubtedly be derived from State taxes. For this reason and because progress in any field of social procedure is impossible except on the basis of a knowledge of existing facts and policies, these authors began, two years ago, studies which undertook to answer two fundamental questions: (1) What types of taxes are our States levying and to what extent are the proceeds of such taxes devoted to public schools? and (2) What State school funds are provided in each of our Commonwealths and in accordance with what principles are such funds apportioned? The primary purpose of the accounts presented in this bulletin is to reveal policies of State origin. For this reason, no attempt has been made to include a description of the methods employed in apportioning funds for vocational education derived from Smith-Hughes subventions and moneys provided by the States or the respective constituent political corporations.
