Neither worked.
The "No Child" law was proposed by President Bush on January 23, 2001 and enacted on January 8, 2002. On February 9, 2012 President Obama approved waivers of the law to 10 states.
Turning Points
Both pieces of legislation had some sort of negative turning point. Today, ironically, in 1929, the Valentine's Day massacre took place, which made people think that the positive outcomes of prohibition might not outweigh the negative ones.
Some might say the turning point for NCLB was when the GOP went back on a promise to provide more federal aid for low-scoring schools to improve. Others might say it was when President Obama announced waivers for 10 states on February 9, 2012.
