Elementary school children in a large public urban school system (Chicago) can be tracked into adolescence, together with their families, by using student numbers established by the Chicago Public Schools. This paper reports on the linkage between a psychiatric follow-up study and the data bank of the Chicago Public Schools. The authors were able to find information about the location and grade placement of 87% of an urban ghetto neighborhood's first grade children after a seven to ten-year lapse in contact. The children about whom information was found did not differ from those missing in the early measures of their school achievement and psychological wellbeing. However, first grade measures of school success of failure did relate to grade placement of children ten years later, as did first grade ratings of bizarreness.
在一个大型城市公立学校系统（芝加哥）中，可以利用芝加哥公立学校分配的学号，将小学生及其家庭追踪到青春期。本文报告了一项精神病学随访研究与芝加哥公立学校数据库之间的关联。在中断联系七至十年后，作者能够找到城市贫民区一个社区87%的一年级儿童的位置和年级信息。找到信息的儿童与那些在学业成绩和心理健康早期测量中缺失信息的儿童并无差异。然而，一年级时学业成败的测量结果确实与十年后儿童的年级安排有关，一年级时的怪异行为评分也与之相关。
