This report describes the fiscal effects of the Chapter 2, Education Consolidation and Improvement Act (ECIA) block grant on the country's largest districts and cities. Although several distinct characteristics are examined, special attention is focused on the differential funding patterns under the block grant in the largest districts that previously received Emergency School Aid Act (ESAA) grants and those that did not. Key findings of this investigation are highlighted in the first section. The second section explains the rationale, objectives, and methodology of the analysis; the objectives were to collect data on allocations to the selected districts under antecedent programs and under the block grant, and to compile information on relevant demographic, fiscal, and programmatic features of the sample districts. The third section presents a detailed explication of cross-time funding patterns under the block grant and its antecedent programs in the country's largest districts and cities. Appendixes provide explanations of district characteristics examined and a discussion of the disparities in funding data for the antecedent programs reported in different data sources. (Author/TE)
