Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i0 In a randomized experiment, students taught by TFA teachers scored higher in math achievement than students taught by comparison teachers, with an impact of about 15 percent of a standard deviation. → Steven Glazerman 2006

q3 · i0 · causal · r?
Randomized experiment studying the impact of Teach For America on student achievement and other outcomes (2001-2004). The study finds "TFA teachers had a positive impact on math achievement" with a printed effect size of "about 15 percent of a standard deviation, equivalent to about one month of instruction."
"TFA teachers had a positive impact on math achievement and no impact on reading achievement. The size of the impact on math achievement was about 15 percent of a standard deviation, equivalent to about one month of instruction."
Discussion¶
Related Claims¶
- The findings contradict claims that alternative teacher preparation programs such as Teach For America harm students — a broader claim this one bears on
- Teach For America teachers had no impact on student reading achievement — related
- TFA teachers have positive effects on mathematics achievement for students in grades pre-K-12, based on six studies — a broader claim this one bears on
- TFA secondary math teachers increase student math achievement by 0.07 standard deviations over one school year relative to other math teachers in the same schools — related
- A randomized controlled trial found TFA secondary math teachers outperformed non-TFA comparison teachers in mathematics achievement — possibly the same claim (merge candidate)
- Teach For America teachers had no impacts on other outcomes such as attendance, promotion, or disciplinary incidents — related
- Secondary math students taught by Teach For America teachers outperformed peers taught by traditional-route teachers by 0.06 standard deviations — related
- Students of certified teachers outperformed students of under-certified teachers, including TFA teachers, on all three SAT-9 subtests in low-income districts — reports the opposite
