As a key predictor of students' academic achievement parental involvement has been in the centre of attention of both educational researchers and policymakers for quite some time. Immigrant parents represent a growing, but under-researched group with its distinctive experiences and expectations. This study provides a systematic synthesis of 40 qualitative and quantitative studies on parental involvement among immigrant parents in North America, Europe, Asia, and Australia. The analysis showed that immigrant parents face unique challenges to their involvement due to language barriers and lack of familiarity with the educational system of a host country. Subsequently, increased pressure on parents to be more responsible for the educational performance of their children may lead to further educational inequalities among diverse groups of learners.
