This study investigated whether family structure accounts for adolescent academic performance in Finland in the analysis. The thirteen- to fourteen-year-old (grade 8) students' (N = 171) literacy skills were measured and their mathematical performance was tested. Information about family structure was gathered via a questionnaire sent to their homes. The findings of the study revealed that adolescents from other than two-parent intact families performed particularly well in regard to literacy skills. There were no gender differences with respect to either skill. The adolescents came from families of each type of structure, across all skill levels, suggesting that adolescent learning outcomes are not determined by diversity in family structure.
