State YBTC Challenge Sites
State YBTC Challenges are held in states with more than one Local Challenge site. Winners from each Local Challenge site participate in the State Challenge for their state. The winner of the State Challenge earns the title of State Challenge Champion and moves on to the National Challenge in Philadelphia!
State Challenges are organized through the collaborative efforts of CEF, Local Challenge Organizers, and other generous sponsors and volunteers.If you would like to be a part of Challenge planning in your state, please contact us atchallenge@chemed.orgto learn how you can get involved.
If your site does not currently have any Local Challenge sites, browse the Local Challenges page to learn how to start the Challenge in your community and in your state!
