In this study, we examine the features of school choice by comparing parental involvement between denominational and public schools. In Hungary, denominational schools reemerged after the fall of communism in 1989, and their share increased further after 2010. The survey data, we employ, refer to primary school children's parents and were focused on parental involvement at home and at school. Our hypothesis is based on the work of Epstein and Coleman and suggests a prominent role for denominational schools in parental involvement. However, our results show that Hungarian denominational schools differ in terms of parental involvement and school choice from what theory or practice in other western countries suggests. School choice of Hungarian parents is primarily driven by the intention to ensure a more culturally and economically homogeneous and safer environment for their children. Parental involvement tends to be stronger at home and at school due to higher parental religiosity, regardless of the school sector. The novelty of our findings is, that opposite to the literature, mostly not the school type but parents' religiosity increase both the home based and the school based parental involvement.
