Middle school Teach For America teachers in Texas seem to be holding their own in the classroom, outperforming other novice teachers in math, according to a recently released study from the San Antonio, Texas-based Edvance, an independent evaluation firm.
TFA alumni also did better than other veteran teachers in that subject, the study found.
The effect size was equivalent to 4+ months of extra time in school.
Some positive effects for English, too, though smaller.
