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.
q1 i? Seasonality, specifically summer loss, affects estimates of school effectiveness, and ignoring summer loss can change which schools are identified as low performers. → NWEA Research 2019

q1 · i? · associational · r?
The research brief's own description states it examines "the effect of seasonality on estimates of school effectiveness" and that ignoring summer loss can impact low-performer identification. No methods, sample, or effect sizes are printed on the page, so this is recorded as an unquantified assertion.
"Learn more about the effect of seasonality on estimates of school effectiveness and how ignoring summer loss can impact which schools are identified as low performers."
Discussion¶
Related Claims¶
- Ignoring summer loss changes which schools are identified as low performers — possibly the same claim (merge candidate)
- Seasonality affects estimates of school effectiveness — a broader claim this one bears on
- School effectiveness estimates from fall-to-spring versus spring-to-spring growth correlate only moderately to strongly (.399 to .705), below the .90 threshold at which rank orderings diverge in accountability — a narrower finding that bears on this claim
- The proposed seasonal growth model combines polynomial terms for year-to-year growth with piecewise terms for within-year gains and losses — related
- School growth estimates based on two years of data correlate around .55–.58 with estimates based on all five elementary years, below the .90 threshold at which ESSA accountability determinations would likely change — related
- Mean achievement in the studied cohort shows a saw-tooth seasonal pattern, with within-year gains followed by summer declines (summer learning loss) — related
