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? Using the same method on the full samples, NWEA districts show .015 SDs math recovery versus .045 for ERS, and -.008 SDs ELA change versus .019 for ERS. → Dan Dewey 2024

Dan Dewey, Erin Fahle, Tom Kane, Megan Kuhfeld, Sean F. Reardon. (2024). Reconciling Recent Evidence on Academic Recovery in the US from 2022 to 2023. https://www.nwea.org/research/publication/reconciling-recent-evidence-on-academic-recovery-in-the-us-from-2022-to-2023/
q2 · i? · associational · r2
Same-method, different-sample comparison applying the ERS recovery methodology to approximately 2,300 NWEA districts and comparing with approximately 5,300 ERS districts. The comparison "still showed significantly different results in the two studies."
"The NWEA data show a far smaller recovery in math than the ERS data (.015 compared to .045 SDs); NWEA data show a negative recovery in ELA (-.008 SDs), while ERS data show a small positive ELA recovery trend (.019 SDs)."
Discussion¶
Related Claims¶
- After excluding Illinois and Ohio, ELA scores showed essentially no recovery from 2022 to 2023 in the remaining 24 ERS states — related
- Math achievement improved by about .045 standard deviations from 2022 to 2023 in the 28 states included in the ERS math sample — related
- The math discrepancy between NWEA and ERS recovery estimates is largely driven by differences in their samples of districts — related
