Desegregation issues continue to be the focus of court litigation in public schools. Since the "Brown v. Board of Education" decision, federal courts have consistently upheld that legally compelled racial segregation of students is a denial of equal protection under the Fourteenth Amendment. Since public school principals play a vital role in implementing court rulings, school board regulations, and state laws, their attitudes toward desegregation litigation is important. This study focused on principals' perceptions, because a 1983 study indicated that Texas schools continue to segregate Mexican-American children. The study attempts to determine the extent of agreement or disagreement toward desegregation rulings by a randomly chosen sample of 600 Texas principals. Using chi-square and other techniques, the study found that a significant percentage of principals agreed with the court decisions. Years of experience and ethnic origin were variables influencing principals' agreement or disagreement with selected court decisions. Sex, type of school, and school district size did not seem to affect agreement or disagreement. Research is needed to determine whether principals' knowledge of school law influences their level of agreement or disagreement. Included is a table analyzing principals' perceptions and seven references. (MLH)
