“On average, high school students taught by TFA corps members performed significantly better on state-required end-of-course exams, especially in math and science, than peers taught by far more experienced instructors. The TFA teachers’ effect on student achievement in core classroom subjects was nearly three times the effect of teachers with three or more years of experience.” …Ms. Hannaway notes, “Students are better off being exposed to teachers with a high level of skill.”
Do you think the teachers’ unions agree with that? Uh, no…. The study referenced in this WSJ op-ed is from the Urban Institute: The Effect of Teach for America on Student Performance in High School. All I’ve had time to read is the Urban Institute summary — the conclusions look plausible, but let’s look for objective critiques of the study. I’ve read enough education study results to appreciate that it isn’t trivial to get reliable, repeatable results.
