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? New research validating the SEDA measures via a common assessment supports SEDA achievement scores. → Megan Kuhfeld 2019
Evidence¶
Megan Kuhfeld 2019¶
Megan Kuhfeld, Thurston Domina, Paul Hanselman. (2019). Validating the SEDA measures of district educational opportunities via a common assessment.

q2 · i? · associational · r?
The brief's own summary of the validation study states that "New research supports SEDA achievement scores". No effect sizes, sample sizes, or test statistics are printed on the page, so the strength of this support cannot be quantified from this source.
"New research supports SEDA achievement scores, but also reveals some differences in growth estimates."
