Step-by-step explanation:
Who Established the 'No Child Left Behind Act'?
The No Child Left Behind Act (NCLB) was established by President George W. Bush. This legislation was signed into law in January 2002 as a significant amendment to the Elementary and Secondary Education Act (ESEA) of 1965. President Bush's administration aimed to bridge the achievement gap between students of varied demographic backgrounds, holding schools accountable for student performance. Under the Act, schools receiving federal funds were subject to a system of testing in reading and math to measure and improve student performance. Schools not meeting certain performance criteria risked corrective actions, including changes in staff or even closure. President Obama's Secretary of Education, Arne Duncan, later sought to address the perceived deficiencies of NCLB.
