In Which We Make Sweeping Generalizations from a Sample of 69 Teach for America Teachers in North Carolina
There is a long discussion of that study here. As I wrote then:
I’m all for Teach for America as a stopgap, but the achievement gap claim is fanciful thinking. Why? By comparison, the black-white gap in NAEP math achievement in grade 12 is approximately 1 standard deviation (and is likely larger because many black students have left by grade 12). An advantage of .04-.1 standard deviations over teachers with 3-5 years experience in the same school is not going to significantly close the achievement gap. This is not an advantage over teachers in the nearest suburb or the best schools in the city that don’t staff TFA teachers, and is hardly a convincing rationale to permanently staff tough schools with a revolving corps of academically talented 2-year teachers.
