“…To date, a number of studies have examined factors during elementary school in relation to convergence of the pre‐K boost. This includes classroom‐level observations of teacher‐child interaction quality (Burchinal et al., 2022; Carr et al., 2019; McCormick et al., 2022); observations of teachers' instruction, planning, and environment based on the Charlotte‐Danielson rubric (Pearman et al., 2020; Swain et al., 2015); measures of structural classroom quality, including teacher degree (Bailey, Jenkins, et a., 2020; Bassok et al., 2019; Jenkins et al., 2018; Magnuson et al., 2007); teacher‐reported measures of teacher‐child relationships (Ansari et al., 2020); measures of instructional content (Burchinal et al., 2022; Jenkins et al., 2018; McCormick et al., 2022); and a measure of the proportion of former pre‐K participating peers in the classroom (Burchinal et al., 2023). Previous studies have also examined school‐ and school district‐level characteristics (Burchinal et al., 2022; Jenkins et al., 2018; Watts et al., 2023) including measures of school‐ or school district‐level achievement growth (Carr, Peisner‐Feinberg, et al., 2021; Carr, Watts, et al., 2021; Pearman et al., 2020; Swain et al., 2015).…”
