I've been doing some work on informational text (used to be called "nonfiction") and why it's important that we change to reading more of it. The Common Core really creates a shift in terms of how much information text students should be reading at all levels.
Since assessment drives everything (in good ways and in bad), how much informational text is on our assessments? This is what I figured out when I looked at it recently.
MCAS—at least 50%
AP English—50% (AP Language—11th grade)
SAT Subject Tests—95%
PARCC Sample Items—about 50%
NECAP—11th grade is 50%
I would conclude that the push for informational text will help students on current assessments and make them more prepared for college and career!
