The document discusses Illinois' adoption of the Common Core State Standards to replace previous state standards. It outlines a three-phase implementation process occurring from 2010-2014. School districts are directed to analyze gaps between the Common Core and current practices, update curriculum maps and identify professional development needs. The Common Core includes fewer and clearer standards in English language arts and literacy, mathematics and other subjects. Gap analysis work has begun in sample districts to identify changes needed at various grade levels in language arts and math.
