Central exams are often hypothesized to favorably affect incentive structures in schools. Indeed, previous research provides vast evidence on the positive effects of central exams on student test scores. But critics warn that these effects may arise through the strategic behavior of students and teachers, which may not affect human capital accumulation in the long run. Exploiting variation in examination types across school systems and over time, we provide the first evidence that central exams positively affect adult skills. However, estimated effects on skills are small and we find no significant average effect on earnings.
