 The movement resulted in the No Child Left Behind Act (NCLB) of 2001, which required that states make yearly progress towards having all students be proficient by 2014, as evidenced by annual standardized testing.In response to growing public disapproval with NCLB as the deadline approached without any state being able to reach this goal, the Obama administration began granting waivers to states exempting them from NCLB testing requirements.The waivers were linked to various reforms, such as the adoption of common standards by a consortium of states, of which the Common Core was the only one.
