This study investigated the relation between multidimensional aspects of high school students' perceptions of their parental involvement and their achievement. It explored differences in socio-economic backgrounds, ethnicity, gender, and higher and lower achieving students, and a structural model was developed to further investigate these relations. A parental involvement questionnaire and measures of efficacy, liking and achievement in mathematics and reading were administered to a sample of 1,554 New Zealand high school students from 59 schools. In the view of students, there is support for parents to be talking to their children about learning and schooling and having high expectations of them and their future in learning, especially for lower achieving students. Students who claim that their parents are talking with their teachers or attending school meetings are more likely to have lower achievement. The implications from this study relate to developing student self-regulation for learning in home, providing more surface than deeper learning as homework, and assisting parents to learn the language of learning and schooling.
