Effects of High-Achieving Peers: Findings from a National High School Assignment System
利用土耳其全国高中分配系统的数据，研究发现进入更具选择性的考试学校能显著提高高成就学生的学业成绩和大学录取结果，这与美国精英学校的研究结论不同。
Recent studies of elite exam schools in the United States have yielded the startling conclusion that such schools improve neither educational achievement nor longer-term educational outcomes. Is the same true for exam schools elsewhere? The education system in Turkey is ideal for investigating this question. There, students are placed in exam schools on the basis of a high-stakes national examination. By use of an exceptional database for Turkey not heretofore available, we conduct regression discontinuity analysis exploiting score discontinuities between more than 200 exam schools. We find that attending more selective exam schools yields large achievement gains and improved university placements for high-achieving students.
