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 i3 Correlations between MAP Growth and MCA-III Mathematics scores in Spring 2019 range from r = 0.92 to r = 0.93 across Grades 3–8, which the authors cite as validity evidence for prediction. → Ann Hu 2021

q2 · i3 · associational · r2
Descriptive analysis of Spring 2019 scores from the Minnesota linking study (Table 3.1), with per-grade samples from 3,355 to 5,621 students. The article reports correlation coefficients of r = 0.92 to r = 0.93, stating "The correlation coefficients between the scores range from 0.92 to 0.93" across Grades 3–8.
"The correlation coefficients between the scores range from 0.92 to 0.93. These values indicate a strong relationship among the scores, which is important validity evidence for the claim that MAP Growth scores are good predictors of performance on the MCA-III tests."
Discussion¶
Related Claims¶
- MAP Growth state-test correlations exceed 0.8 for most Grade 3-8 concurrent indices, with mathematics correlations higher than reading — a broader claim this one bears on
- MAP Growth spring RIT cut scores classify students as proficient or not proficient on the MCA-III Mathematics test with 0.87–0.90 overall accuracy — related
- Linking studies connect MAP Growth scores to state summative proficiency predictions and external measures — a broader claim this one bears on
- Proficiency projections estimate the probability of reaching Meets proficiency on the state test from fall, winter, or spring RIT scores — related
