A Game of Inches
One of the more telling episodes in education I’ve seen over the past couple of years was a little dispute over Michelle Rhee’s testing record that flared up last year. Alan Ginsburg, a retired U.S. Department of Education official, released an informal report in which he presented the NAEP cohort changes that occurred during the first two years of Michelle Rhee’s tenure (2007-2009), and compared them with those during the superintendencies of her two predecessors.
Ginsburg concluded that the increases under Chancellor Rhee, though positive, were less rapid than in previous years (2000 to 2007 in math, 2003 to 2007 in reading). Soon thereafter, Paul Peterson, director of Harvard’s Program on Educational Leadership and Governance, published an article in Education Next that disputed Ginsburg’s findings. Peterson found that increases under Rhee amounted to roughly three scale score points per year, compared with around 1-1.5 points annually between 2000 and 2007 (the actual amounts varied by subject and grade).
Both articles were generally cautious in tone and in their conclusions about the actual causes of the testing trends. The technical details of the two reports – who’s “wrong” or “right” – are not important for this post (especially since more recent NAEP results have since been released). More interesting was how people reacted – and didn’t react – to the dueling analyses.
