Students who repeat a grade are at a higher risk of dropping out of high school. Previous research has examined this in a methodologically aggregated way (e.g., repeated any grade versus never repeated) or only specific grades/grade ranges (e.g., Kindergarten or elementary) leaving questions about which grades are more detrimental to repeat with respect to school dropout. This study uses data from the National Center for Education Statistics (N = 9,309) to comparatively examine which grades, when repeated, show the strongest associations with dropping out. Overall, those who repeated sixth or seventh had the highest odds of dropping out of high school with unique patterns by gender and race/ethnicity. These grades are typically when youth transition into middle school. When examined through a developmental lens, these results highlight the important impact that grade retention while youth experience other normative physical, cognitive, and social changes.

复读成绩的学生更有可能辍学。先前的研究以方法学上的汇总方式（例如，重复任何等级而不是从未重复）或仅特定等级/等级范围（例如，幼儿园或小学）对该问题进行了检查，从而提出了关于哪个等级对辍学的危害更大的问题。本研究使用国家教育统计中心（N= 9,309），以比较检查哪些成绩在重复时显示出与辍学之间的最强关联。总体而言，那些重复第六或第七次考试的人，按性别和种族/民族划分的独特模式，高中辍学的几率最高。这些成绩通常是在青年过渡到中学时提出的。当从发展的角度来看时，这些结果突出了年级保持率的重要影响，而青年经历了其他规范的身体，认知和社会变化。
