This study asks how Finnish 6-year-olds who stay at home before school start compare in educational outcomes with children who attend public day care. Earlier studies have shown that participation in public day care can enhance school performance especially among disadvantaged children. In Finland, the child home care allowance scheme supports the home care of 6-year-olds if they have a younger sibling under the age of 3 who is also not attending public day care. We used as outcome variables grade point average after compulsory school at age 15 to 16 and dichotomous variable measuring completion of further education by age 25. The study utilized data of the birth cohort 1987 (N = 4,928). The results show that staying at home before school start is associated with poorer school performance but not with completion of further education.
