ABSTRACT This study investigates the impact of parental involvement on the education outcomes of their children, specifically focusing on the completion of high school. It extends the existing literature by considering the characteristics of both children and parents, and by examining non-school-related parental involvement in a child’s everyday life. The analysis utilizes a publicly available database, the National Longitudinal Survey of Youth 1997, with a sample of American respondents born between 1983 and 1984 who lived with both birth parents during their early teenage years. The study employs simple logistic regression and subclassification on propensity score to estimate causal treatment effects. The results indicate that higher parental involvement is associated with an increased probability of high school graduation, while stricter parental behaviour is found to decrease the expected likelihood of completing high school.
