This report summarizes data that address several aspects of the Elementary and Secondary Education Act's Title I program. It includes information on districts, schools and students served, range of instructional and support services provided, Title I staffing patterns, and schools' progress toward meeting performance standards as reported in Title I performance reports submitted by states in the U.S. The report illustrates the scope of the Title I program during two successive school years and identifies emerging trends in the design and implementation of the programs conducted in participating districts and schools nationwide. The document addresses the Title I Grants to Local Educational Agencies Program Part A. The Part A program provides federal financial assistance to eligible school districts and schools to aid their efforts in helping children meet challenging standards, with a particular emphasis on children who are at risk of not meeting such standards. Information is also provided on the Title I State Agency Program for Neglected or Delinquent Children and Youth, which provides free public education to children in institutions for neglected or delinquent children, in addition to educating juveniles through the age of 21 who are in adult correctional institutions.
