No Child Left Behind
The No Child Left Behind Act, or NCLB, was a federal education-reform bill that was signed into law by President George W. Bush in 2002. NCLB reauthorized the Elementary and Secondary Education Act of 1965.
NCLB provided federal money to schools to improve academic outcomes among students. The primary purpose of NCLB was to ensure that students in every public school achieved important learning goals while being educated in safe classrooms by well-prepared teachers.
NCLB was replaced with the Every Student Succeeds Act in 2017.
