Ten years after its inception, it appears increasingly clear that NCLB will not meet its ambitious 2014 goals

No Child Left Behind is in shambles.

In a report released Thursday, the Center on Education Policy found that 48 percent of the nation's public schools failed to meet NCLB goals in 2011. This is up from 39 percent in 2010 and 29 percent in 2006. Furthermore, there is a great disparity in the performance among states. For instance, 11 percent of Wisconsin schools fell short of advancement goals; in Florida, that number was 89 percent.

In addition to a divergent, confusing map of educational progress across the country, the report makes it clear that NCLB will not make succeed in reaching its main goal of all states being proficient by 2014 -- especially with statistics showing that the number of schools missing the mark is increasing each year.

The Center's report also points out a glaring flaw in way states measure Adequate Yearly Progress, NCLB's means of judging schools' performance. The problem: there's simply no consistency. Each state sets its own standards, creating its own proficiency goals, testing with its own exams, and reporting its progress with its own metrics. But still, according to the report, "if a school fails to make AYP [Adequate Yearly Progress] for two consecutive years or more, it is considered 'in need of improvement' and must submit to certain interventions mandated by NCLB that are intended to improve achievement."
