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? In the 2015-2016 growth period, Idaho charter students' gains do not differ statistically from TPS peers in either reading or math. → CREDO 2019
q2 i? In the 2016-2017 growth period, Idaho charter students' reading gains are significantly higher than TPS peers, about 24 more days of learning. → 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?
Growth-period disaggregation of the statewide VCR analysis. The 2015-2016 period shows no statistically significant difference in either subject; equivalence was not otherwise tested.
"The gains of Idaho charter school students in the 2015 -2016 growth period do not differ statistically from the performance of their TPS peers in either reading or math."
CREDO 2019 (2)¶
CREDO, Center for Research on Education Outcomes, Stanford University. (2019). Charter School Performance in Idaho. https://credo.stanford.edu
q2 · i? · causal · r?
In the 2016-2017 growth period of the same VCR analysis, charter students' reading gains are significantly higher, with growth of approximately 24 more days of learning in reading compared to TPS counterparts; math gains show no statistically significant difference.
"the gains of Idaho charter school students in the 2016-2017 growth period are sign ificantly higher than the growth of their TPS peers in reading"
