Did Rheeformers Rhee and Henderson Actually Close Any of Those Achievement Gaps in DC Public Schools?
Part Sixteen and Final
Today we look at the black-white and hispanic-white achievement gaps in the Washington, DC public school system, which has now been under mayoral control for seven full years.
My four graphs and tables today will show how laughably pitiful their claims of success really are.
You will see that the achievement gap is pretty much unchanged since the year I retired (2009), but the gap between Rhee’s promises and reality has been getting wider and wider.
A lot of their promises had to do with closing the ‘achievement gaps’ between white and more-affluent students on the one hand, and black, white, and impoverished students on the other hand. As you probably are aware, standardized test scores are very strongly linked to family income and educational levels. You may not be aware that the white population of Washington DC is generally very well-educated.and fairly affluent (unlike rural white populations in, say, West Virginia or Kentucky). Washington has the highest-scoring white student body in the nation on the National Assessment of Educational Progress (NAEP), and the widest gap between the scores of white students and of hispanic or black students.
However, Michelle Rhee and her minions promised spectacular reductions in those gaps, as measured by the relative percentages of students scoring ‘proficient’ or ‘advanced’ on the DC-CAS among white students, hispanic students, black students, and students who are eligible for free and reduced-price lunches (versus those not eligible).
What I found is a complete and utter failure to make any progress whatsoever since 2008 or 2009 — the year that Rhee twisted the arms of every single principal in the school system to come up with miraculous gains, and when many of those principals (and Did Rheeformers Rhee and Henderson Actually Close Any of Those Achievement Gaps in DC Public Schools? | GFBrandenburg's Blog:
