Who Benefits from a Smaller Honors Track?
利用北卡罗来纳州高中数据，研究荣誉班规模变化对不同成绩学生成绩的影响，发现缩小荣誉班（占学生20%-30%）能提升顶尖学生成绩，但扩大比例对中等生有微小增益，却损害底层学生。
<h3>Abstract</h3> This paper characterizes the efficiency and distributional impact of changing the share of students enrolling in honors classrooms. Using North Carolina high school data, we estimate functions capturing the test score impact of alternative honors enrollment shares by predicted performance quintile. We find that smaller honors tracks (20%-30% of students) yield moderate performance gains for top quintile students (~.05-.07 score SDs relative to trackless courses) that decline monotonically across quintiles toward zero for bottom quintile students. However, expanding the honors share beyond 30-35% generates further (small) gains only for the middle quintile, while reducing top quintile gains and causing substantial bottom quintile losses.
