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? Students in middle charter schools experience the weakest growth, equivalent to 35 fewer days of learning than TPS VCRs in both reading and math. → CREDO 2019
q2 i? Multi-level charter school students post the strongest reading growth, equivalent to 24 additional 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?
Grade-configuration disaggregation of the VCR comparison (elementary, middle, high, multi-level). Middle charter school students trail their TPS virtual twins by an equivalent of 35 fewer days of learning in either subject.
"Students in middle charter schools experience the weakest growth compared to their TPS virtual twins in both reading and math, where they have an equivalent of 35 fewer days of learning than TPS VCRs in either subject."
CREDO 2019 (2)¶
CREDO, Center for Research on Education Outcomes, Stanford University. (2019). Charter School Performance in Idaho. https://credo.stanford.edu
q2 · i? · associational · r?
In the same configuration analysis, multi-level charter students post the strongest reading growth versus their TPS virtual twins, equivalent to 24 additional days of learning, with similar math growth.
"charter multi-level school students post the strongest academic growth compared to their TPS virtual twins in reading. Their growth in math is similar ."
