Common Core state standards for English Language Arts & Literacy
This document gives some insight into the Common Core texts that are being suggested as exemplars for fiction, poetry, drama and informational texts at the different grade levels. (Note: they aren't a reading list per se.)
"The text samples listed primarily serve to exemplify the level of complexity and quality that the Standards require all students in a given grade band to engage with. Additionally, they are suggestive of the breadth of texts that students should encounter in the text types required by the Standards. The choices should serve as useful guideposts in helping educators select texts of similar complexity, quality, and range for their own classrooms. They expressly do not represent a partial or complete reading list."
