From an educator's perspective the greatest difference between Common Core State Standards and the State Standards that were mandated under No Child Left Behind (NCLB) is academic rigor and consistency. Under NCLB each state had to create their own standards for every subject area. Some states had higher standards and expectations than others. If you made standards easy, more students would be marked proficient under NCLB. Common Core State Standards were developed by a consortium of states. What we are experiencing now is a gap between holding students to basic standards and holding them to high standards. Most states adopted Common Core State Standards or similar versions of the standards so that they could waive the mandates of No Child Left Behind.
