Assessments

What Assessment Scores Are Computed?

The NLSY79 Child data files contain summary scores for each assessment measure. For a subset of assessments, subscores are constructed. Where available, the user is provided with national norms based on the raw scores. Table 1 lists the raw and normed scores that are available for the most recent Child survey year. The data file includes individual item responses as recorded in the field as well as interviewer reports of testing conditions for each assessment. Edit or imputation "flags" are constructed for selected assessments to indicate where prorations were necessary or where alternate scoring schemes were considered.  Scoring procedures are addressed below in relation to specific assessments.

Members of the CHRR staff have examined the assessment data as carefully as possible while preparing the assessment scores for the public use files. Researchers who encounter data or documentation problems with the assessments are encouraged to contact NLS user services. Should a problem be detected, we will inform data users by posting updates to NLSinfo.org and by correcting subsequent public releases.

Other child assessment documentation. Key references related to the assessments are cited in the References section. Users interested in additional research based on the NLSY79 child assessment data are encouraged to access the annotated, online NLS bibliography at www.nlsbibliography.org.

Detailed information about the validity of the Child data through the 1992 survey round can be found in the NLSY79 Children 1992: Description & Evaluation.  Background information on the child assessment data in the initial child survey rounds is discussed in The NLSY Child Handbook. Both documents are available on the Research/Technical Reports page.

Tables that describe the Child assessment scores in each survey round, starting with the 1994 data collection, can be found in a series of reports entitled The NLSY79 Child Assessments: Selected Tables. These reports display distributions of the raw and normed assessment scores by various child characteristics such as age and race/ethnicity. They are also available on the Research/Technical Reports page.
