On December 10, 2015 President Obama signed into law the Every Student Succeeds Act which does away with provisions of the No Child Left Behind Act. The four versions of the bill [S.1177.ENR] are available from THOMAS (The Library of Congress).
The White House blog post of Dec. 7, 2015 compares President Obama'a priorities for the Every Student Succeeds Act with those of the Bipartisan Bill and No Child Left Behind. The Senate Legislative Activity page shows the main provisions of the act while the Education Week blog explains them.
