Desegregation in the Jefferson County Public Schools (Kentucky) deteriorated in many key aspects but improved in two others during 1983-84. The percentage of schools out of compliance with student enrollment guidelines rose and the number of black teachers fell to their worst levels since school desegregation began. The number and percentage of black vocational teachers also fell to new lows. On the positive side, the distribution of black teachers among schools, and the number and percentage of black administrators improved over 1982-83. School officials' actions and inaction created seemingly unmanageable problems used to justify replacing the desegregation plan in use since 1975-76 with a revised plan. School administrators will need to disclose full and accurate desegregation data if the community is to succeed in monitoring implementation of any future desegregation plan. (Author)
