High School Longitudinal Study of 2009

HSLS:09 follows a nationally representative cohort of Fall 2009 9th-graders as they progress through high school and transition into postsecondary education and/or the labor force. The study also contains a special emphasis on exploring the path that leads students to pursue and persist in courses and careers in STEM fields. This cohort was reinterviewed in 2011, 2012, 2013, and 2016.

A school-level file is available for the Base Year (2009).
