This report is based on 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. The cohort was surveyed again in spring 2012 when most students were in the eleventh grade. The 2012 survey included questions about whether students had left their base-year school and asked the reasons why. This Data Point focuses on the 11.5 percent of students in the HSLS cohort who reported that they changed their educational setting by transferring schools or becoming homeschooled between the time they were surveyed in 2009 and the time they were surveyed in 2012. The following statistics are presented: (1) What are the self-reported reasons that students change their educational setting?; and (2) Do student-reported reasons for changing their educational setting vary by socioeconomic status (SES)?
