What does NCLB stand for?

The acronym NCLB stands for No Child Left Behind, which was a significant piece of legislation enacted in the United States in 2001. This law aimed to improve educational outcomes for all students, particularly those from disadvantaged backgrounds, by holding schools accountable for student performance and requiring assessments to measure progress. The primary goal was to close the achievement gap and ensure that every child received a quality education, regardless of their socioeconomic status.

The other options do not accurately reflect what NCLB stands for. They either reference organizations or initiatives that do not exist or do not pertain to the context of educational legislation in the U.S. The focus of NCLB was specifically on accountability in education and improving access to quality education for all children, making "No Child Left Behind" distinctly recognizable and relevant in discussions about educational policies and reforms.
