This report from the 2018 Cardus Education Survey examines the school sector effect on education and career outcomes for graduates of nongovernmental and public schools in the U.S. It is based on a representative survey of 1500 randomly selected American high school graduates (ages 24-39). The Cardus Education Survey includes a large number of controls for many factors in student development such as parental education, religion, and income, to isolate a school sector’s particular impact.
