Improving the signal quality of grades
研究如何通过改进大学评分政策来提高成绩的信号质量，从而更准确地识别优秀学生，减少他们错失选择性机会的情况。以法学院为例，利用40年成绩单数据，发现调整人员、课程和评分政策能显著提升识别效果。
Abstract We investigate how improving the signal quality of grades could enhance the matching of students to selective opportunities that are awarded early in academic programs. To do so, we develop methods to measure the signal quality of grades and to estimate the impact of changes to university policies on the identification of exceptional students for these opportunities. We focus on law schools, a setting where students are awarded important academic and professional opportunities after just one year of a three-year program. Using transcript data from a top law school over a 40-year period, we document large gains in identifying exceptional students if changes were made to certain personnel, course, and grading policies. Our findings provide motivation and a blueprint for how universities could leverage their internal records to ensure that fewer exceptional students miss out on selective opportunities.
