School desegregation was implemented in New Castle County, Delaware, in September 1978. This longitudinal study examines the changes that have occurred in the attitudes of students and parents after the first year. Initial differences in attitudes and changes in attitudes for both students and parents are discussed according to original school district (city or suburban), race, sex, grade level, and socioeconomic status. Findings indicate that after one year of school desegregation, racial attitudes among all students became less positive and that perceived school quality declined among parents. The study reveals, however, that attitudes of parents towards school desegregation itself became more positive. (Author/APM)
