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? Classification agreement between SWCPM-predicted and ARM-based performance categories is moderate to high: exact match rates range from 74.6 to 90.8 percent and Cohen's kappa from 0.60 to 0.85. → NWEA Psychometrics and Analytics 2024
q2 i? For the two-category proficient/not-proficient decision, overall classification accuracy rates range from 0.81 to 0.96, which the authors interpret as SWCPM being effective at classifying students. → NWEA Psychometrics and Analytics 2024

NWEA Psychometrics and Analytics 2024¶
NWEA Psychometrics and Analytics. (2024). Predicting Amira Reading Mastery Based on NWEA MAP Reading Fluency Benchmark Assessment Scores. https://www.nwea.org/research/publication/predicting-amira-reading-mastery-based-on-nwea-map-reading-fluency-benchmark-assessment-scores/
q2 · i? · associational · r2
Classification accuracy analysis of the weighted linking sample (Tables 3.9 and 3.10) against ARM-defined proficiency, with per-grade Ns from 3,102 to 12,622. The report also states overall classification accuracy "rate ranges from 0.81 to 0.96."
"The exact match rates range from 74.6 to 90.8. Cohen’s kappa values range from 0.60 to 0.85. Both the exact match rates and Cohen’s kappa values suggest a moderate to high level of agreement."
Discussion¶
Related Claims¶
- Literacy screener benchmarks predict which grade 3 students will not meet MCAS ELA expectations, but not necessarily who will meet them — the general claim this finding bears on, with the studies behind it
- MAP Reading Fluency SWCPM scores correlate highly with Amira Reading Mastery scores (r = 0.90–0.96) across grades 1–5 in fall and winter — related
- SWCPM score ranges corresponding to ARM performance levels show monotonic progression across terms within grades, except in first grade — related
- The KEI threshold was accurate for the cohort despite large individual-level prediction errors (53% of proficient and 73% of non-proficient students correctly classified) — related
- Agreement between K–3 screening assessments on risk classification varied from 47 percent to 85 percent depending on the assessment combination — related
- Linear regression outperformed equipercentile and mean-sigma equating for predicting ARM scores and was selected as the final linking model — related
- A body of work standard setting process produced classification agreement rates ranging from 71% to 97% for an alternate portfolio assessment — related
