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? Model-based estimates show math within-year growth of 13.4 RIT in second grade, slowing at roughly 1.4 RIT per year across school years. → Soland 2019

q2 · i? · associational · r2
Fixed-effects estimates from the CP growth model fit to MAP Growth data, math centered at Grade 2 (Table 3). Estimates are model-based with printed standard errors; descriptive parameters only, so impact is null.
"students increase their test scores between fall and spring of second grade by an estimated 13.4 RIT. However, that within-year growth from year one slows as students move through school at a rate of roughly 1.4 RIT per year."
Discussion¶
Related Claims¶
- Within-year (fall-to-spring) achievement gains decelerate linearly as students move through school, at roughly 1.4 to 4 RIT per year depending on subject and centering grade — related
- In the study data, mean spring grade-2 math RIT was 190.6 with linear spring-to-spring growth of 14.5 RIT, and mean fall-to-spring gain in grade-2 math was 13.4 RIT — related
- Mathematics growth in Grades 1-3 is nonlinear with deceleration, so more growth occurs in the first half of the school year, and average growth rates decline across grade levels — related
- More of the variance in linear growth lies at the school level for fall-to-spring than for spring-to-spring estimates, in some cases twice or three times as much — related
