The relationships between occupation, education and intellectual ability at 30 years of age are analysed with particular reference to type of school attended at the age of 14 years. Data utilized are derived from interviews, psychological tests, local files of various schools, and journals of the National Services for Mentally Retarded. The study comprises all live births in the year 1940 of mothers then residing in Bergen, a total of 1570 persons. A sample was taken from this cohort after stratification according to type of school attended at age 14 years. The sample was supplemented with persons who had either attended Special Schools for the educable Mentally Retarded (EMR) or received care from the Services for the Mentally Retarded (SMR). The final sample consisted of 262 persons. A relationship was found for both sexes between type of school attended at the age of 14 years and level of general education at the age of 30. For men, both occupational training acquired and intellecutal ability at 30 years were also clearly related to type of school attended at age 14 years. The test performance of the male group was superior to that of the female group. Differing careers in the two sexes may provide a clue as to the reason underlying this finding.
以14岁时所就读学校的类型为特别参照，分析了30岁时职业、教育与智力之间的关系。所使用的数据来自访谈、心理测试、各类学校的本地档案以及国家智障服务机构的期刊。该研究涵盖了1940年当时居住在卑尔根的母亲所生育的所有活产婴儿，共计1570人。在根据14岁时所就读学校的类型进行分层后，从这一队列中抽取了一个样本。该样本还补充了那些就读于可教育智障特殊学校（EMR）或接受过智障服务机构（SMR）护理的人员。最终样本由262人组成。研究发现，14岁时所就读学校的类型与30岁时的普通教育水平在男女两性中均存在关联。对于男性而言，30岁时所获得的职业培训和智力也与14岁时所就读学校的类型明显相关。男性组的测试表现优于女性组。两性不同的职业发展轨迹或许能为这一发现背后的原因提供线索。
