description: The National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. The additional files contained in this component of the Add Health project are from the Adolescent Health and Academic Achievement (AHAA) study and provide an opportunity to examine the effects of education on adolescent behavior, academic achievement, and cognitive and psychosocial development in the 1990s. The AHAA study contributes to Add Health by providing the high school transcripts of Add Health Wave III sample members. The AHAA data provides indicators of (1) educational achievement, (2) course taking patterns, (3) curricular exposure, and (4) educational contexts within and between schools, all of which can be linked to the Add Health survey data.

description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Performed consistency checks.; Standardized missing values.; Checked for undocumented or out-of-range codes..

description: Wave I, Stage 1 School sample: stratified, random sample of all high schools in the United States. A school was eligible for the sample if it included an 11th grade and had a minimum enrollment of 30 students. A feeder school, a school that sent graduates to the high school and that included a 7th grade, was also recruited from the community. Wave I, Stage 2: An in-home sample of 20,745 adolescents consisting of a core sample from each community plus selected special oversamples was interviewed in 1995. Eligibility for the oversamples was determined by the adolescent's responses on the In-School Questionnaire. Adolescents could qualify for more than one sample. At Wave II, respondents who were in grades 7-11 at Wave I were re-interviewed. Wave III: The in-home Wave III sample consists of Wave I respondents who could be located and re-interviewed six years later. Wave III also collected High School Transcript Release Forms to be used for the AHAA study. At Wave IV, 15,701 Wave I respondents were re-interviewed in 2008.
