A Metaregression Analysis Of The Effects Of School Racial And Ethnic Composition On K-12 Reading, Language Arts, And English Outcomes

Racial and ethnic differences in educational outcomes significantly narrowed during the 1970s and 1980s when K-12 public schools were desegregated. However, when schools resegregated starting roughly in the late 1980s, racial gaps in outcomes widened again. Because of literacy's pivotal role in learning, the authors investigate if segregation contributes to racial gaps in K-12 reading performance. Drawing upon structural vulnerability and cumulative advantage/disadvantage theories to frame this study, the authors conduct multilevel metaregression analyses of 131 effect sizes from 30 primary studies to investigate if school composition effects contribute to racial gaps in K-12 reading outcomes and if any effects vary in magnitude or direction for students from different racial/ethnic backgrounds or grade levels. The metaregression analyses control for the primary studies' regression model characteristics and research designs. The results indicate a small, negative, statistically significant relationship between the percentage of a school's disadvantaged minority enrollment and the mean reading achievement of the students who attend it. The negative association is stronger when segregation is measured by percentage Black and is stronger for high school students. These two findings suggest that the disadvantages of segregated education cumulate as more structurally vulnerable students transition from elementary to secondary school. Additional results suggest that a school's racial composition effect is not the same as its socioeconomic status composition effect. The two organizational characteristics have distinct, albeit interrelated, influences on reading scores. Together the findings suggest that racially and ethnically segregated schooling both reflects and helps reproduce racial/ethnic inequality in literacy outcomes.
