This 25th annual report summarizes recent activities in Ohio that were provided by means of Chapter 1 of the Elementary and Secondary Education Act. Information presented concerns: (1) statistics for fiscal 1990; (2) participation trends; (3) instructional impact; (4) expenditure and staffing patterns; (5) parent involvement; and (6) 5-year trends. Initial discussion explains the basic Chapter 1 services provided by Ohio's public school districts. Statistics for the current year and 5-year trends clearly indicate that the program helps children become successful learners. Subsequent discussion describes the special Chapter 1 services provided for the children of migratory agricultural workers and handicapped, neglected, or delinquent children who are being educated in state agency schools. Statistics related to this part of the discussion also indicate the beneficial human impact of the supplemental services provided through federal aid to education. Thirty-four tables supplement the text. (RH)
