The author, director of UCLA's Institute for Democracy, Education, and Access, shares results of a study he led exploring how principals in U.S. high schools are responding to five specific societal challenges; he highlights what principals said about the challenge of gun violence in their schools. More school leaders reported their school being affected by the threat of gun violence than by any of the other four issues--and they see students and student learning impacted by fears about guns. Rogers shares aspects of the gun violence problem that principals must deal with, their perspectives, and various ways principals and schools are responding.
