Home-school partnerships are widely promoted for the positive impact they can have on students’ motivation, engagement, behaviour, and academic and social outcomes. A comprehensive meta-analysis comparing a wide range of educational interventions found that parent involvement had a larger effect on student academic achievement than most other interventions. However, the benefits of parent involvement in one school subject or area are also found to be confined to that area, that is, parent involvement in reading improves students’ reading attainment but not their attainment in mathematics.
