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? · associational · r?
Large-scale analysis of science test scores across seven school years (2019 through 2024), described by the authors as "the first large-scale, in-depth analysis of how science achievement in the U.S. was influenced by the COVID-19 pandemic." No effect sizes are printed in the available text.
"As part of this study, our researchers examined science test scores across seven school years to understand how COVID-19 influenced science achievement."
Discussion¶
Related Claims¶
- NWEA's 2024 technical brief examines pandemic impacts on science achievement and gains from 2019 through 2024, continuing research on COVID-19 school-closure effects on learning — possibly the same claim (merge candidate)
- Pandemic-period gains from fall 2019 to fall 2021 fell short of pre-pandemic growth norms — related
- Student achievement at the start of the 2021-22 school year lagged pre-pandemic norms, especially in math — related
- Reading and math gains during 2020-21 were diminished compared to pre-pandemic trends, especially in the latter half of the school year — related
- A 2021 review series aims to provide a definitive account of the best available evidence on how the COVID-19 pandemic affected America's students academically — a broader claim this one bears on
- BIPOC students' math achievement in fall 2020 dropped substantially relative to pre-pandemic national norms, with the largest declines in grades 4-6 — related
- The “From loss to recovery” brief examines two components of school recovery post-COVID to understand diverging recovery patterns across schools — related
