We examined levels of financial literacy (knowledge, attitudes, self-efficacy, and self-reported behavior) among 15-year-old high school students in the Netherlands (N=2025), and investigated which factors are associated with the different financial literacy components. Our findings show lower levels of financial literacy among students in the lowest track in high school, students with low mathematical ability, immigrant students, students with low SES, students with mothers without a university degree, and students who do not discuss financial matters with family and peers. Notably, our findings show a large gap in financial knowledge levels between the lowest and highest high-school tracks in the Netherlands. These findings are useful for designing effective financial education and intervention programs, and for identifying groups that may benefit the most from financial education programs.
