East Side Charter & NYC Success Academy Benefit Immensely From Attrition & Proficiency Scores

On Diane Ravitch’s blog, she wrote an article today based on an editorial in the Wall Street Journal about the attrition rate at the Success Academy in Harlem.  The editorial, by Michael Mulgrew, the President of the United Federation of Teachers in NYC, pointed out Success Academy 13 in Harlem has very high attrition rates and high-needs children frequently leave the school.  This puts the school at an advantage in terms of proficiency scores on standardized testing.

Two months ago, Nelia Dolan pointed out that in one year, East Side Charter in Wilmington had 62 children in one grade, and their scores were lower on DCAS.  The scores dramatically improved the next two years, however that same group of kids was reduced to 29.  This illusion of improvement plays out constantly in Delaware and across America.  Success is only as great as the true story, and the story by Mulgrew gives some startling facts:

“While Ms. Moskowitz cites a recent report from the city’s Independent Budget Office about student attrition in charters, she neglects to mention an earlier IBO report that found that it is the less successful students who tend to leave New York City charters. And as Princess Lyles and Dan Clark note “Keeping Precious Charter-School Seats Filled,” op-ed, Feb. 3), failure to fill these seats allows a school to maintain “the illusion of success,” as the percentage of proficient students rises.”

As Governor Markell continues to compare the six priority schools in Wilmington to East Side Charter and Booker T. Washington Elementary School in Dover, he forgets these types of facts.  Booker T., I recently found out, also holds the district’s gifted and talented program for elementary schools in the district.

Say, didn’t one of Delaware’s biggest charter supporter also write an editorial about the myth of cherry-picking in Delaware charter schools?  I seem to recall that….
