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? Students in the bottom decile of pre-pandemic achievement had larger initial impacts at the pandemic's onset and made less improvement during 2021-22 than other students. → Karyn Lewis 2022

q2 · i? · associational · r2
Longitudinal follow-up of a subset of 1 million students whose pre-pandemic achievement placed them in the top or bottom decile relative to national pre-pandemic norms. The brief reports "Low achievers experienced larger initial impacts at the onset of the pandemic and less improvement during 2021-22."
"Low achievers experienced larger initial impacts at the onset of the pandemic and less improvement during 2021-22."
Discussion¶
Related Claims¶
- The achievement divide between high and low achievers widened significantly over the last two years of the pandemic — related
- Pandemic-period growth varied by pre-pandemic achievement status: higher achievers' gains were more consistent with projected normative growth while lower achievers more often fell short — possibly the same claim (merge candidate)
- Pandemic-period gains from fall 2019 to fall 2021 fell short of pre-pandemic growth norms — related
- End-of-2021-22 student achievement remained lower than a typical year, with larger declines in math (5 to 10 percentile points) than reading (2 to 4 percentile points) — related
- Student achievement at the start of the 2021-22 school year lagged pre-pandemic norms, especially in math — related
- The 2021-22 COVID learning study investigated fall 2021 achievement versus pre-pandemic fall 2019 levels and fall 2019 to fall 2021 gains versus normative growth expectations — related
- COVID-19 learning deficits arose early in the pandemic and have neither closed nor substantially widened since then — reports the opposite
- School-aged children experienced a substantial overall learning deficit during the COVID-19 pandemic (pooled d = −0.14), equivalent to about 35% of a school year's learning — related
- AI-supported PBL offerings showed higher A-rates and fewer low grades than pre-integration control offerings when including the COVID-19 year — related
