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.
q2 i? Corresponding overall false positive error rates are about 10 percent and false negative error rates about 20 percent. → Peter Z. Schochet 2010

q2 · i? · theoretical · r?
Simulation-based error rate analysis of value-added performance classification systems. The abstract states "error rates for overall false positive and negative errors are 10 and 20 percent, respectively" under the studied measurement schemes.
"Corresponding error rates for overall false positive and negative errors are 10 and 20 percent, respectively."
Discussion¶
Related Claims¶
- Overall false positive error rates are about 10 percent and false negative error rates about 20 percent for value-added performance classifications — possibly the same claim (merge candidate)
- Error rates for comparing a teacher's performance to the average are about 25 percent with three years of data and 35 percent with one year of data — related
- Value-added error rates apply to measuring both teacher and school performance in the upper elementary grades using student test score gain data — related
- The working paper examines the sensitivity and precision of teacher value-added estimates under specifications differing in student-level, peer-level, and double-lagged achievement controls — related
