This Data Point utilizes data from the High School Longitudinal Study of 2009 (HSLS:09), a nationally representative, longitudinal study of more than 23,000 ninth-graders in 2009. HSLS:09 surveyed students, their parents, math and science teachers, school administrators, and school counselors. The study included information about students who were enrolled in school in the fall term of 2009 as ninth-graders and who were not enrolled in school and had not earned a regular high school diploma or alternative credential such as a GED in spring 2012, when they should have been 11th-graders. These students are referred to as “dropouts” in this report
