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? Charter students in Idaho experience higher academic progress than their TPS peers in reading, equivalent to 24 additional days of learning in a 180-day school year. → CREDO 2019
q2 i? The difference in math growth between Idaho charter students and their TPS VCRs is not statistically significant. → CREDO 2019 (2)
Evidence¶
CREDO 2019¶
CREDO, Center for Research on Education Outcomes, Stanford University. (2019). Charter School Performance in Idaho. https://credo.stanford.edu
q2 · i? · causal · r?
Statewide quasi-experimental analysis comparing all matched Idaho charter students with their Virtual Control Records across two growth periods, 2014-15 to 2016-17. Charter students show "higher academic progress than their TPS peers in reading," equal to 24 additional days of learning.
"charter students in Idah o experience higher academic progress than their TPS peers in reading. This advantage for charter students is equivalent to 24 additional days of learning in reading in a 180 -day school year."

q2 · i? · causal · r?
The same statewide VCR comparison finds no statistically significant math difference; the report states charter students experience "similar growth in the 180 -da y period as they would have in a traditional school setting." No effect size is printed.
"Because the difference in the growth in math is no t statistically significant, Idah o charter students experience similar growth in the 180 -da y period as they would have in a traditional school setting."
