Willingness to spend on education is influenced by many factors. This article presents hypotheses concerning socio-demographic and economic determinants for household spending on Polish children’s education. These hypotheses were tested on the data from an exploratory study “Household educational spending and its determinants”, which was conducted by the Educational Research Institute in Poland in 2012. The main goal of this research was to characterise private household spending on education. Determinants of total, obligatory and other private household expenditure on education were analysed using OLS regression. Obligatory expenditure on school not only includes fees, but also all expenditure required for formal education such as textbooks and uniforms. The analysis showed that the cultural capital of households, parents’ education and family wealth had significant influence on their educational expenditure. Parental opinions about school were also significant as a predicator.
