The CHKS is sponsored by the California Department of Education. It is a very important survey that will help promote better health among our youth, improve the school learning environment and combat problems such as drug abuse and violence. The survey was developed by WestEd, a public, non-profit educational institution. If you have any questions about this survey, or about your rights, call Dr. Michael Corke (619) 594-2635 at the City Heights Educational Collaborative.
