Parent engagement in education has been shown to have positive effects on students' academic and social/emotional success. However, much of the research has focused on younger students. Less attention has been given to parent engagement at the secondary level, especially with respect to how parents choose to engage and how adolescents perceive this engagement. This article reviews the literature on parent engagement at the secondary level, focusing on its importance to academic achievement, high school completion rates, and social-emotional functioning. Factors influencing parents' decisions to become engaged are discussed, including parental self-efficacy, role construction, and specific invitations from the child. Parent engagement remains important at the secondary level, though parent behaviors appear to change to match the developmental needs of students. Implications for practice and future research are discussed.
