The studies presented by Reardon, Kalogrides, and Ho provide preliminary support for a National Assessment of Educational Progress–based aggregate linking of state assessments when used for research purposes. In this commentary, I suggest future efforts to explore possible sources of district-level bias, evaluation of predictive accuracy at the state level, and a better understanding of the performance of the linking when applied to the inevitable nonrepresentative district samples that will be encountered in research studies.

关于Reardon，Kalogrides和Ho的“聚合级测试量表链接的验证方法：将学区测试成绩分布映射到一个通用量表的案例研究”的评论

Reardon，Kalogrides和Ho提出的研究为基于国家教育进展评估的州评估的总体链接提供了初步支持。在这篇评论中，我建议未来的工作，以探索区级偏差的可能来源，评估州一级的预测准确性，以及将其应用于不可避免的非代表性区样本时更好地理解链接的性能。研究研究。
