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.

Discussion¶
Related Claims¶
- The 2025 MAP Growth norming sample showed no systematic differences from the U.S. public school target population on selected school-level correlates, with no standardized mean difference reaching the 0.2 threshold — related
- Norming-sample testing volume is concentrated in kindergarten and grade 1, which together account for more than 70% of test events — related
- EISA-based MAP Growth testing produced slightly lower fall Mathematics scores but higher winter and spring Mathematics scores than traditional MAP Growth, and equipercentile linking was used to align the two versions for norming — related
- The 2025 MAP Growth norms adopted a two-year, two-level piecewise mixed-effects design because two consecutive years of data are sufficient for within-year and adjacent-year growth norms — related
- The course-specific MAP Growth norms were built from 747,936 test events administered to 342,821 students in Grades 6–12 across 50 states between Fall 2017 and Spring 2019. — related
- The 2025 MAP Growth Norms are based on national test samples from 2022–23 and 2023–24, and dashboard results are not comparable to reports using 2020 norms — related
