The Education Longitudinal Study of 2002 (ELS:2002; https://nces.ed.gov/surveys/els2002/) is a study that is a part of the Education Longitudinal Study program. It is a longitudinal survey that monitors the transitions of a national sample of young people as they progress from tenth grade to, eventually, the world of work. In 2004, the sample was augmented to make it representative of seniors as well. The study was conducted using self-administered questionnaires and cognitive tests of students, parents, teachers, librarians, and school administrators. Students and their high school administrators, library media coordinators, mathematics and English teachers, and parents in the spring term of the 2002 school year were sampled. The study's base year weighted response rate was 87.3 percent for students, 98.5 percent for school administrators, 95.9 percent for library media coordinators, 91.6 percent for both mathematics and English teachers, 87.5 percent for parents, and 67.8 percent for schools. Key statistics produced from ELS:2002 focus on the changes taking place in the lives of students which can be understood by life achievements, aspirations, and experiences.
