No Child Left Behind (NCLB) or commonly referred to Nicle B.

The No Child Left Behind Act of 2001 (No Child Left Behind) is a landmark in education reform designed to improve student achievement and change the culture of America's schools. President George W. Bush describes this law as the "cornerstone of my administration." Clearly, our children are our future, and, as President Bush has expressed, "Too many of our neediest children are being left behind."

With passage of No Child Left Behind, Congress reauthorized the Elementary and Secondary Education Act (ESEA)--the principal federal law affecting education from kindergarten through high school. In amending ESEA, the new law represents a sweeping overhaul of federal efforts to support elementary and secondary education in the United States. It is built on four common-sense pillars: accountability for results; an emphasis on doing what works based on scientific research; expanded parental options; and expanded local control and flexibility.
