q3 · i? · associational · r2

Analysis of MAP Growth assessment data from "6 million students in grades 3-8" comparing fall 2021 achievement and pandemic-period gains to pre-pandemic trends; the brief reports achievement lagged norms, "especially in math." No effect sizes are printed in the available text.

"The results showed that, on average, both student achievement at the start of the 2021-22 school year and student gains across the pandemic (from fall 2019 to fall 2021) lagged pre-pandemic norms, especially in math."
