No Child Left Behind (NCLB) was passed in 2001 to improve education through standard-based tests and funding tied to scores. However, it failed to provide adequate funding and over-emphasized testing at the cost of a well-rounded education. President Obama promised changes including reducing the high-stakes of standardized tests, measuring student growth, and increasing early childhood programs and parent involvement. These changes aim to better support teachers and students while maintaining NCLB's goals of accountability and improved school quality.
