Abstract: Parent's participation in education has a positive effect on primary school pupils' academic performance. In this article foreign scientific researches on psychological pedagogy devoted to the correlation between parents' participation and school success, published between 2009 and 20019 in peer-reviewed academic journals, are observed. Authors examined the conceptual approaches to determining a parents' participation in the educational process and its main forms - participation in school life and homeschooling and its connection with the academic performance of primary schoolers. The theoretical analysis of literature was used as the principal method of the research of main approaches to the solution of the studied scientific problem. On the developed topic, were studied researches, identified by searching the Web of Science and PsychINFO databases. As a result of the study, there were determined individual variables of parents' participation which are directly connected with success in primary school: 1) home reading, 2) parental expectations and aspirations, 3) communication between parents and children on school education and 4) parental encouragement and support for learning. Variables, which mediate the connection between parents' participation and school success, based on certain types of parent's participation (at school and at home), were determined. The results of the study deepen and expand knowledge about the correlation between different forms of parents' participation in education and school performance of primary schoolers. The authors' recommendations can be used to improve the strategies of educational interaction between the school and pupils' families, aimed at developing measures to prevent school failure.
