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? Average CSEM values are fairly similar across deciles, with lowest values in middle score deciles and somewhat larger values at the lower and upper ends, especially in Reading's first decile. → MAP Growth Technical Report Spanish Addendum for 2024–2025 2026

q2 · i? · design · r2
CSEM analysis by subject, grade, decile score group, and term (Figure 4.3, Tables 4.5–4.6). A MAP Growth test event targets "a CSEM of about 3.3 RIT points", and precision was broadly consistent across demographic subgroups.
"average CSEM values are fairly similar across deciles within each subject, with the lowest values generally observed among students in the middle score deciles and somewhat larger values observed at the lower and upper ends of the score distribution"
Discussion¶
Related Claims¶
- MAP Growth reliability coefficients average about 0.95, with lower values in Science and early grades and stronger test-retest reliability over shorter intervals — related
- Reliability of state test scores is highest near cut-scores or the mean and much lower for very high- or low-performing students — a broader claim this one bears on
- DC estimates tend to be lowest when the cut score is set at the peak of the score distribution, where inconsistent decisions are most likely — related
- Spanish examinee RIT scores and item difficulty increase on average from kindergarten through high school, with item difficulty matching student ability — related
- Spanish Math and Reading scores show high marginal reliability and moderate-to-strong test-retest stability, lowest for fall–spring and kindergarten — related
