In the broadest sense parent involvement in schools refers to “parents’ involvement in their children’s education”. This chapter examines the effects of socioeconomic factors on parent involvement in their children’s education, both at home and in school. It reviews the effects of parent involvement, including parental attitudes toward education, on student achievement. The chapter profiles the effects of a variety of school intervention programs for disadvantaged students, which employ a heavy parent involvement component. It indicates that parents’ involvement in their children’s education is directly related to their academic achievement. Although parents who are socioeconomically disadvantaged tend to participate less in their children’s education, school programs to involve parents can help offset the negative effects of poverty.
