The 4th UC Davis C-STEM Day was held on May 31, 2014. This year it was expanded to two locations: UC Davis and UC Irvine. The 2014 C-STEM Day was organized by the UC Davis Center for Integrated Computing and STEM Education (C-STEM). Coastline ROP also co-organized the C-STEM Day at UC Irvine. More than 40 HP and Intel volunteers as well as volunteers from other companies at the UC Davis location served as judges for the RoboPlay Challenge Competition and the Math Programming Competition.
