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? Previous charter school research has shown mixed results for student achievement, which could be the consequence of different policy environments or methodological approaches with differing assumptions across studies. → Ron Zimmer 2012

Ron Zimmer, Brian Gill, Kevin Booker, Stéphane Lavertu, John Wittle. (2012). Examining Charter Student Achievement Effects Across Seven States. Economics of Education Review, vol. 31, issue 2. https://www.mathematica.org/publications/examining-charter-student-achievement-effects-across-seven-states
q2 · i? · causal · r?
The publication's summary paragraph states, as background motivation, that "Previous charter school research has shown mixed results for student achievement" and offers two candidate explanations: differing policy environments and methodological approaches with differing assumptions. No effect sizes or study counts are printed on the page.
"Previous charter school research has shown mixed results for student achievement, which could be the consequence of different policy environments or methodological approaches with differing assumptions across studies."
