Title I, Part A, of the Elementary and Secondary Education Act (ESEA) authorises federal aid to local educational agencies (LEAs) for the education of disadvantaged children. Title I-A grants provide supplementary educational and related services to low-achieving and other pupils attending pre-kindergarten through grade 12 schools with relatively high concentrations of pupils from low-income families. In recent years, they have also become a "vehicle" to which a number of requirements affecting broad aspects of public K-12 education for all pupils have been attached as a condition for receiving Title I-A grants. This book examines the formulas used to allocate Title I-A funds to states, LEAs, and schools. These formulas are used to allocate funds not only under the largest federal K-12 education program, but also several other ESEA and non-ESEA programs under which grants are made in proportion to ESEA Title I-A allocations.
