This report describes the methodology and presents the findings of a survey of State education agencies concerning the extent of eligibility of school districts for ESEA Title I schoolwide projects and the extent of their participation in such projects. Information provided includes: (1) the number of districts that applied for Title I funds in the 1979-80 school year; (2) the number of these districts having at least one school with 75 percent or more children eligible for Title I; (3) within these districts, the number of schools with 75 percent or more Title I eligible children; (4) the number of districts that applied for a Title I schoolwide project for the 1979-80 school year; and (5) the number of districts that have, or will have, at least one Title I schoolwide project during the 1979-80 school year. Five percent of the districts applying were found to meet the eligibility criterion for schoolwide projects by having at least one school with 75 percent or more Title I eligible children. It was also found that while eligible districts tended to be concentrated in high poverty Southeastern States and in States with medium enrollments and high poverty rates, they occurred throughout the nation.
