This pamphlet from the U.S. Department of Education provides information about FERPA and the steps that school officials are allowed to take in order to ensure school safety, including during health or safety emergencies. Also explained are whether FERPA applies to law enforcement unit records (collected by security staff at schools), security videos, and personal knowledge or observation. (posted November 5, 2012)
