From the study: "The purpose of this study was to explore the reading performance scores of elementary school students in one school district before and after school closures due to COVID-19. This nonexperimental, exploratory study of quantitative, archival data was designed to explore a single cohort (N = 2,006) of third- through fifth-grade students’ i-Ready reading diagnostic scale scores from five different assessment periods: before school closures in spring 2020 and four subsequent assessment periods after face-to-face instruction resumed in fall 2020."
