The article focuses on the effect of federal policy on services delivered through Title I of the Elementary and Secondary Education Act in the U.S. Title I has two main purposes. The first is to provide districts with support that will allow them to offer educational services to students who both need the services and who reside in low-income areas. The second is to provide services, which expand the Title I student's regular curriculum. These requirements are meant to insure that the services provided by Title I are related to the needs of the children to be served, and that they are carefully planned, implemented and evaluated. Although these requirements determine to some extent whether Title I does expand and improve services, four of the eight fund allocation provisions have a much greater effect. These are the comparability, supplement not supplant, excess costs, and equitably provided requirements. The comparability requirements are school-level requirements. Generally, they require that the level of services provided from state and local funds in every Title I school be comparable to the average level in non-Title I schools.
