- There is a connection between whites being out of the public school system and a predominance of African Americans in the same districts’ public schools.
- Public schools do worse than public schools students in districts with relatively few White students in nonpublic schools.
- Both of the school-level characteristics (racial composition of schools and average socioeconomic family background of students in schools) are significantly related to school performance. The greater the percentage of Black students in a school, the lower the average score of that school; conversely, the higher the average socioeconomic background of students in a school, the higher the average score.
- In districts that have many White students in nonpublic schools, the educational advantage of family socioeconomic background is less closely related to test performance, and the gap between Whites and Blacks is greater.
- The withdrawal of White students from the public school system has a negative impact on schools because it results in the concentration of minority students in public schools.
- Parents who choose to send their children to nonpublic schools, rather than public schools, can, by following their own self-interest, create an interesting and troubling sociological dilemma.
- The withdrawal of White students from the public school system is negatively related to academic achievement because it tends to concentrate minority students in public schools.
- There indeed appears to be a correlation between the percentage of White students enrolled outside of the public school system and the concentration of minority students enrolled outside of the public school system and the concentration of minority students in public schools in the same district.
- Whether White students are in public school systems or not appears to make a difference. Individual test scores are lower in districts in which the White students tend to be outside of the public school system. Further, the Black-White gap is greater in districts with many Whites in nonpublic schools.
- Heavy representation of whites in nonpublic schools is related to the school performance of students because districts with large White nonpublic school populations tend to have greater minority predominance in the public schools.
