Littleton Public Schools is proud to be implementing the Colorado Academic Standards (CAS) and the Common Core State Standards (CCSS). The Colorado Academic Standards were adopted by the state of Colorado in December 2009. In August of 2010, Colorado joined 44 other states in adopting the Common Core State Standards for English Language Arts and for Mathematics. Both sets of standards reflect 21st Century learning and college and career readiness skills. During the 2013-2014 year, most content areas across K-12 in LPS will be implementing these new standards.
