The National Center for Education Statistics (NCES) in August 2013 released selected findings from the 2011-12 Schools and Staffing Survey (SASS), a nationally representative survey of public and private school principals and teachers.

The survey offers a rich assortment of information about schools, the people who run them, and the students who attend them. It turns out, for example, that 64 percent of graduates from all private high schools and 81 percent of graduates from Catholic high schools go on to a four-year college. The same is true for 40 percent of graduates from traditional public schools and 37 percent of graduates from public charter schools.
