The Minnesota Executive Function Scale (MEFS) is a subscription service for assessing executive function skills using a brief, standardized instrument administered on an iPad®. Executive function refers to the neuro-cognitive skills needed for successful learning and performance in school, at work, and in life. They include cognitive flexibility, working memory, and inhibitory control. How does the MEFS work? The MEFS is easy to use, but is intended to be administered only by trained and certified examiners. That is how you can be sure the MEFS results and norms are reliable and valid.

The Early Years Toolbox (EYT) Preschool Situational Self-Regulation Toolkit (PRSIST) Assessment assesses young children’s cognitive and behavioral self-regulation, through observer ratings of children as they engage in authentic, semi-structured activities. Specifically, in one group activity (e.g., memory card game in a group of four) and one individual activity (e.g., curiosity boxes guessing game), an adult facilitating the activity rates aspects of each child's cognitive self-regulation (e.g., sustaining attention, remaining engaged) and their behavioural self-regulation (e.g., resisting impulses, remaining within the rules of the activity). Each rating consists of 8 items, which are explained and described to guide ratings. Free online training in using this tool is available at www.prsist.com.au/assessment.html. This site also provides a full description of PRSIST activities. This assessment takes an average of 8 minutes to complete per child. Scores are presented on the final assessment screen. For more information on PRSIST, visit www.prsist.com.au. For more information on the Early Years Toolbox, see http://www.eytoolbox.com.au About the Early Years Toolbox: The 'Early Years Toolbox' (EYT, for short) is comprised of brief, engaging game-like assessments of children’s self-regulation, executive functioning and vocabulary. These assessments are based on well-established and widely used measures, yet have been adapted and optimised on the basis of 20+ years of research experience working with young children.
