About ETSAt ETS, we advance quality and equity in education for people worldwide by creating assessments based on rigorous research. ETS serves individuals, educational institutions and government agencies by providing customized solutions for teacher certification, English language learning, and elementary, secondary and postsecondary education, and by conducting education research, analysis and policy studies. Founded as a nonprofit in 1947, ETS develops, administers and scores more than 50 million tests annually -including the TOEFL ® and TOEIC ® tests, the GRE ® tests and The Praxis Series ® assessments -in more than 180 countries, at over 9,000 locations worldwide. The early education field increasingly is recognizing the key role played by young children's executive function (EF) skills, generally defined as the cognitive abilities that consciously support goal-directed behaviors. To provide the field with an overview of research conducted on this topic over the past 15 years, we review research on the traits and skills that fall under the broader umbrella of preschool EF and the role it plays in young children's developmental and academic outcomes. Also addressed are the child, environmental, activity-related, and curricular factors potentially impacting the development of EF and some EF-related topics for which additional research is needed. Finally, we provide practical and psychometric information regarding six examples of measures that focus on assessing preschoolers' EF skills. This report can serve as a resource for early childhood researchers and practitioners who are interested in understanding EF development during the early years. By highlighting some topics for which additional research is needed and providing information regarding examples of valid and reliable measures to assess EF in children ages 3-5 years, we hope this report also will serve as a springboard for future studies related to preschool EF.Keywords Executive function; preschool; assessment doi:10.1002/ets2.12148The early education field is increasingly recognizing the key role played by young children's executive function (EF) skills, generally defined as the cognitive abilities that consciously support goal-directed behaviors (Diamond, 2006;Garon, Bryson, & Smith, 2008). This recognition is important given the continued policy emphasis on expanding at-risk children's access to publicly funded prekindergarten (Barnett et al., 2016) and the central role that EF skills play in children's learning and overall school readiness (Blair, 2002;Blair & Razza, 2007;Obradovic, Portilla, & Boyce, 2012;Zelazo, Blair, & Willoughby, 2016). The extent to which EF may serve as a critical contributor to children's early education outcomes may be particularly salient in light of recent data on the out-of-school suspension rat...
