Diane Ravitch Explains Why She Changed Her Mind

about "school reform." To sum up, it's because it won't work and is destructive to public education:

Although this target was generally recognized as utopian, schools faced draconian penalties—eventually including closure or privatization—if every group in the school did not make adequate yearly progress. By 2008, 35% of the nation's public schools were labeled "failing schools," and that number seems sure to grow each year as the deadline nears.

Since the law permitted every state to define "proficiency" as it chose, many states announced impressive gains. But the states' claims of startling improvement were contradicted by the federally sponsored National Assessment of Educational Progress (NAEP). Eighth grade students improved not at all on the federal test of reading even though they had been tested annually by their states in 2003, 2004, 2005, 2006 and 2007.

Meanwhile the states responded to NCLB by dumbing down their standards so that they could claim to be making progress. Some states declared that between 80%-90% of their students were proficient, but on the federal test only a third or less were. Because the law demanded progress only in reading and math, schools were incentivized to show gains only on those subjects. Hundreds of millions of dollars were invested in test-preparation materials. Meanwhile, there was no incentive to teach the arts, science, history, literature, geography, civics, foreign languages or physical education.

In short, accountability turned into a nightmare for American schools, producing graduates who were drilled regularly on the basic skills but were often ignorant about almost everything else. Colleges continued to complain about the poor preparation of entering students, who not only had meager knowledge of the world but still required remediation in basic skills. This was not my vision of good education.
