This is a report of school desegregation in Greenville, Mississippi. In 1964, five years before ordered to do so by a federal judge, Greenville initiated its own plan for majority-to-minority crossover of students on a "freedom of choice" basis. The school board also initiated a voluntary teacher transfer program that met with considerably more success than did the student program. Mutual switches could be and were arranged among the teachers and administrative teacher transfers supplemented the rolls of volunteers. By 1968, just prior to the court order, the previously all white high school had a black student representation of 15%. No white, however, had exercised the freedom to choose the all black high school or any of the all black elementary schools. Another drawback to the Greenville voluntary choice program was that the degree of desegregation was dependent on availability of space in the schools requested. Pressure from the minority community for deliberate speed, expressed through lawsuits filed in court in the mid-1960's, was the impetus for the plan now in operation. Almost everyone interviewed during the case agrees that leadership for implementation came from the students themselves. Today, desegregation of the Greenville public schools is very nearly total. The initial loss of about 15 to 19% of the white students through flight to private schools was the major development during implementation. The single greatest problem according to white administrators, remains how to get back the students from the private academies and to create a closer approximation of the real world mix of people than is presently offered in the schools.
