The Effects of Reducing Tracking in Upper Secondary School: Evidence from a Large-Scale Pilot Scheme
利用瑞典教育改革前的大规模试点，研究了增加职业轨学术内容、减少与学术轨差异的政策效果，发现该政策提高了职业学生的受教育年限，但未影响大学入学率或未来收入。
By exploiting an extensive pilot scheme that preceded an educational reform, this paper evaluates the effects of introducing a more comprehensive upper secondary school system in Sweden. The reform reduced the differences between academic and vocational tracks through prolonging and increasing the academic content of the latter. As a result, all vocational students became eligible for university studies. The results suggest that the policy change increased the amount of upper secondary schooling obtained among vocational students, but did not affect enrollment in university studies or students' earnings later in life.
