Latinos, particularly Mexican immigrants, are the fastest-growing population in the United States but lag behind others in educational attainment. Parent involvement in their child's education has been linked to positive student academic outcomes, but few studies have focused specifically on Latino/a parents. To identify and promote culturally salient parent involvement approaches for Mexican immigrant parents, this qualitative strength-based study investigated motivations, actions, and culture of 11 Mexican immigrant parents of students who attended a selective college preparatory high school. The study found that a parent's effort to help their children succeed is not dependent on high levels of parent education or income. Rather, the home-based strategies, many of which are rooted in the Latino culture, and specific outreach by educators influenced parent involvement.
