The first of three major shifts in the English Language Arts/Literacy Framework is building knowledge through content-rich informational text. In grades K-5, the 2009 reading framework of the National Assessment of Educational Progress (NAEP) recommend a 50/50 balance between literary and informational reading, based on the understanding that students need to gain knowledge about the world as they read. In grades 6–12, there is an even greater emphasis on informational reading, affording students more opportunity to build knowledge in various disciplines through reading, writing, and literacy skills while meeting the increased rigor of standards in their other subjects.
