Add Health Cohort/Academic Year Match

This example illustrates how course-taking and survey data match up for students enrolled in 9th grade in the Fall of 1994. For this cohort, their 9th grade course-taking (considered their “Year 1” of high school) occurred during the same year as the In-School and Wave I surveys. Wave II corresponds with their second year of high school course-taking (their “Year 2”). The linking indicators in the AHAA data set provides school year and grade level indicators which enable analysts to match Add Health respondents’ Wave I survey data to their transcript-determined academic year placement (i.e. Year 1, Year 2, Year 3, Year 4).
