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? Concordance studies found fall Mathematics scores in most grades slightly lower for EISA users than comparison groups, while winter and spring Mathematics scores in all grades were higher, producing increased within-year growth relative to comparison groups. → 2025 MAP Growth Norms Technical Manual 2025

q2 · i? · associational · r2
Section 2.6 reports concordance studies (attributed to Lewis and Kuhfeld 2024) comparing EISA and traditional MAP Growth; the manual states fall Mathematics scores "were slightlylowerforEISAuserscomparedtocomparisongroupsusingtraditionalMAPGrowthassessments" and that winter and spring scores in all grades were higher. No effect sizes are printed.
"results from pilot and follow-up concordance studies showed that fall Mathematics scores in most grades were slightlylowerforEISAuserscomparedtocomparisongroupsusingtraditionalMAPGrowthassessments"
