Aptitude, Achievement & Intelligence Scores

The NLSY79 Child surveys contain a wide range of detailed assessment information about the children of female respondents. Since 1986, a battery of child cognitive, socio-emotional, and physiological assessments has been administered biennially for age appropriate children. Assessments related to aptitude, achievement, and cognitive ability are listed below. Each individual assessment is discussed in more detail in the Assessments section of the topical guide. Users may also wish to review the Introduction to the Assessments section, which contains general information about the administration of the child assessments.
