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? The strong linear HSGPA–graduation trend (coefficient 0.703) does not vary significantly by high school; only the small quadratic term varies slightly (0.103). → Allensworth 2019

Allensworth 2019¶
Allensworth, Elaine M., & Clark, Kallie. (2019). Are GPAs an Inconsistent Measure of College Readiness across High Schools? Examining Assumptions about Grades versus Standardized Test Scores.

q2 · i? · associational · r3
Random-slope hierarchical model of students nested in high schools (n=17,753). The article states the "noise that is introduced by variation in the linear and quadratic components is small relative to the signal from the linear slope (0.703)".
"The strong linear trend (coefficient of 0.703), does not vary significantly by high school. The quadratic term (coefficient of 0.062) does vary slightly across schools (0.103)."
Discussion¶
Related Claims¶
- ACT scores show a weak relationship with college graduation, with slope variation across high schools larger than the average signal — related
- HSGPA has a strong, positive relationship with college graduation that does not vary significantly in its linear slope across high schools — possibly the same claim (merge candidate)
- HSGPAs have a strong, consistent relationship with college graduation that is larger than school effects, while ACT scores have a weak relationship smaller than high school effects with slopes varying by school — a broader claim this one bears on
- HSGPA strongly predicts six-year college graduation among four-year college enrollees, with odds of graduating doubling per standard deviation of HSGPA — related
- Adding ACT scores to models with HSGPA contributes little to the prediction of college graduation and does not reduce between-school variability — related
- ACT scores weakly predict college graduation, and the school-level variance in the ACT slope (0.192) exceeds the average slope (0.129), so school effects introduce more noise than the ACT signal — related
- Both HSGPA and ACT strongly predict four-year college enrollment and enrollment in colleges with strong graduation rates — related
- For four-year (rather than six-year) graduation, ACT scores are slightly predictive but their coefficient is one-sixth the HSGPA coefficient — related
