本文讨论了在实验性项目评估中使用倾向评分来估计由项目特征和参与者的项目经验定义的亚组的影响。作者讨论了估计问题，并提供规格测试。他们还讨论了一个被忽视的数据收集设计的使用-获得预测，该计划的招生工作人员对申请人的可能的计划任务和经验-这可以提高匹配的比较样本的质量。他们证明了这种方法的有效性，在生产可靠的亚组调查结果使用的数据，从大规模的实验评估工作队，全国最大的联邦教育和培训计划的弱势青年。
This article discusses the use of propensity scoring in experimental program evaluations to estimate impacts for subgroups defined by program features and participants' program experiences. The authors discuss estimation issues and provide specification tests. They also discuss the use of an overlooked data collection design—obtaining predictions that program intake staff make about applicants' likely program assignments and experiences—that could improve the quality of matched comparison samples. They demonstrate the effectiveness of this approach in producing credible subgroup findings using data from a large-scale experimental evaluation of Job Corps, the nation's largest federal education and training program for disadvantaged youths.
