The relation between executive functions and school performance in healthy adolescents

How well do executive function tests and questionnaires predict school performance in healthy adolescents? This was investigated in 173 healthy adolescents aged 12-­18 years who study at pre-university education level (in Dutch: vwo). Executive functions were measured with the D-­KEFS subtests Sorting Test and Tower Test, and with the BRIEF-­SR. School performance was measured with end of term grades for Dutch, English and mathematics
