“…A second limitation of the extant research evaluating at‐scale public preschool programs is a near‐exclusive focus on academic outcomes, ignoring EF (for exceptions, see Ansari et al, 2020; Weiland & Yoshikawa, 2013). Evidence from evaluations of specialized curricula or interventions focused on improving EF in preschool contexts suggests preschool may improve children's EF skills at the end of the preschool year (e.g., Bierman et al, 2008; Day et al, 2022; Diamond et al, 2007; Howard et al, 2020; Raver et al, 2008). Given that EF skills have long been considered “cornerstones of development” because they facilitate success in other domains (Robson et al, 2020; Shonkoff & Phillips, 2000; Spiegel et al, 2021), it is important to consider whether, for how long, and to what extent there may be impacts of more typical preschool attendance on EF that continue during and beyond kindergarten.…”
