The Department of Education’s National Center For Education Statistics offers this database of colleges, private schools, public schools, and libraries. You can search by different ways, including state and city, zip code, distance, and by name. Once you find the institution you are looking for you will get detailed information about the college, public or private school, or library. The information is usually detailed even for private schools, Example: http://nces.ed.gov/surveys/pss/privateschoolsearch/school_detail.asp?Search=1&SchoolID=AA890885&ID=AA890885
