High School Longitudinal Study of 2009 (HSLS:09) First Follow-up Restricted-use Data File

HSLS:09, the most recent of the secondary school longitudinal studies sponsored by NCES, follows a nationally-representative cohort of students who were in 9th grade in the fall of 2009. The first follow-up of HSLS:09 was conducted approximately two and a half years after the base year collection, in 2012. This newest wave includes data provided by students and their parents, math and science teachers, and school staff—both administrators and counselors. HSLS:09 emphasizes math and science as well as preparation for postsecondary education and the first follow-up features the following innovations: (1) HSLS:09 collected data from administrators in schools to which HSLS students transferred between fall of 2009 and 2012; (2) School counselor input on school programs available to students and families for postsecondary education and career planning was collected; and (3) The mathematics assessment added two new difficulty levels so that student growth in college preparatory math subjects could be studied.
