The Myth of the Super TFA Teacher is Crushed by TFA’s Own Research

A study conducted in Texas with the cooperation of Teach for America claims to pretend that TFA teachers are more effective than their peers. We’ve all heard this claim before, including from frauds like Michelle Rhee, who made up fables about her mythical and fantastic successes during her three years as a TFA newbie in Baltimore.

However, the facts and tables in the report itself shows exactly the opposite, at least for TFA members who are in their first two years (and for many of them, their only two years) in the classroom.

For example, look at the following tables, which I cut and pasted from the report:

how TFA teachers compare with their peers

Notice what the data is saying in the first four bar graphs above. Dark blue means that the students of that group of TFA teachers were significantly more likely to pass the STAAR test than the students of other, matched, non-TFA teachers. Black means that the students of that group of TFA teachers were NOT more likely to pass, and that this is statistically significant.

Also notice that they do NOT ask the question of whether students of TFA teachers do significantly worse on that test than do students of other teachers. We can only guess.

(1) During the first year that a TFA ‘corps member’ is in the classroom, in 44% to 46% of the cases, their students do NOT do significantly better than their peers on a state-wide standardized test than do the students of non-TFA teachers. We don’t know for a fact that the students actually did WORSE than those taught by non-TFA teachers, but it is certainly a strong possibility. Only in 1/6 to 1/4 of the cases (16% to 26%), do the students of the TFA first-year teachers do significantly better than the students of other, comparable teachers.

(2) Apparently students of second-year TFA teachers in Texas do even worse than those of first-year TFA teachers, especially in reading, because the dark blue sections of the third and fourth bar graphs are significantly smaller than those for the first and second bar graphs, and the black section of bar graph 3 (reading) is much larger than it was in bar graph 1.

Bar graphs 3 and 4 include both first year and second year TFA teachers; since the combined figures for both years 1 and 2 are much worse than for just year 1, that must mean that TFA teachers get worse at preparing their students for the STAAR test during their second year.

(3) However, the relatively few TFA corps members who successfully exit TFA and go on to remain as classroom teachers apparently do much better than the peers that were selected by this study (that’s bar graphs 5 and 6; note the dark blue sections are much larger).

However, let me quote the conclusions written by the authors of this report concerning this graph:

“Students of TFA alumni were significantly more likely to pass STAAR Reading and Math in 77% and 82% of all Reading & Math analyses, respectively. TFA corps members are more effective in Math than Reading. ”

I will let you, the reader, make your own decision as to whether preparing students to pass tests like the PARCC or the STAAR is a worthy goal. But it’s almost all the data that we have.

Thanks to Gary Rubinstein for his blog post, pointing me towards this study.
