Aptitude, Achievement, and Intelligence Scores (Young Men's Cohort Only)
Scores from various aptitude and intelligence tests were collected for respondents in the Young Men cohort during the 1968 survey of high schools. Designed primarily to gather information on the characteristics of the secondary school most recently attended and on respondents' academic performance, the survey also collected information on the names of the most recent scholastic aptitude or intelligence test (R01711.-R01718.) taken by those respondents who were subjects of the survey. A composite score is available that combines the results from such tests as the Otis/Beta/Gamma, the California Test of Mental Maturity, and the Lorge-Thorndike Intelligence Test, as well as the PSAT, SAT, and ACT college entrance examinations. The composite score is referred to as the 'IQ Score' (R01711.) and is described in the appendix to Kohen (1973). Table YM1 lists each test and the number of respondents for whom data are available. Additional information on this survey can be found in the "High School & College Surveys" section.

One assessment, the "Knowledge of the World of Work" scale (R00297.-R00325.), was directly administered to the Young Men in 1966. The first part of this scale asked respondents to pick one of three statements that best described the duties of each of ten jobs commonly held by men. For each of these jobs, the respondent then stated how much education was required (i.e., less than a high school diploma, high school diploma, some college, college degree). Finally, the respondent was presented with eight pairs of occupations and asked which of each pair had higher average wages. Several subscores and a total score (R00616.-R00619.) were calculated by survey staff; derivations for these scores are provided in the codebook.
IQ scores were constructed using scores from the tests available from school records (Kohen 1973). While there may be psychometric problems in constructing an IQ measure from a variety of test forms, these constructed variables assist the user who wishes to construct a unified score from having to repeat the work involved in pooling scores. Similar information is available for respondents in the Young Women cohort.
Survey Instruments: The separate instrument called the Young Men and Women School Survey (1968) collected the test score information. The Knowledge of the World of Work scale is located in the "Knowledge of the World of Work" section of the 1966 questionnaire.
Documentation: Appendix 9 in the Young Men Codebook Supplement contains useful background information on the 1968 school survey and details certain variable creation procedures.
