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.

Evidence¶
Matthew Johnson 2026¶
Matthew Johnson, Naihobe Gonzalez, Jeffrey Max, Tareena Musaddiq, Sophia Seifert, Michelle Bennett, Ren Schlosser. (2026).

q2 · i? · causal · r?
Quasi-experimental comparison of 9th-grade on-track NSI students to similar students in comparable schools. The report prints an improvement in course pass rates of "3 to 4 percentage points"; no standardized effect size is printed.
"The NSI improved students' grade point average (GPA) by about 0.11 points on a 4-point scale, and improved course pass rates by 3 to 4 percentage points."

q2 · i? · causal · r?
Quasi-experimental comparison of 9th-grade on-track NSI students to comparable non-participating students. No reduction in suspension rates was detected; equivalence was not tested.
"These NSI did not reduce suspension rates."
