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? Goodness-of-fit analyses indicate the constructs measured by the Spanish tests across language background groups are at least tau-equivalent and mostly parallel equivalent, supporting use with students of different language backgrounds receiving different classroom instruction. → NWEA 2021

q2 · i? · design · r2
Internal-structure validity analysis (Chapter 8) of goodness-of-fit indices for the Spanish MAP Growth Reading tests. The report concludes the constructs are "at least tau-equivalent and most of them are parallel equivalent" across language background groups; no fit index values are quoted in the text provided.
"Overall, the goodness-of-fit results indicate that the constructs measured by the Spanish MAP Growth Reading tests across language background groups are at least tau-equivalent and most of them are parallel equivalent."

Related Claims¶
- English and Spanish MAP Growth Reading scales were statistically linked via a bilingual group design despite measuring similar but not identical constructs — related
- MLGM model fit failed for the Indiana mathematics test, the sole exception to invariance support — related
- DIF study finds most items in category A, with C DIF rare (~1%) except for the Native English/Bilingual group (6.66%) — related
- The authors conclude that MAP reading and mathematics CAT constructs are invariant across five time points in ten states (except Indiana mathematics), though their mathematics tables show strong-invariance CFI drops above 0.01 in most states — related
- Most Spanish test items show negligible differential item functioning across gender and Hispanic–White comparisons — related
- TRC-Spanish is the assessment least correlated with the others, though strongly correlated with TRC-English — related
