Early Years Toolbox (EYT) Go/No-Go is an iPad-based assessment of children's inhibition (i.e., ability to control behavioural impulses). In this game, fish and sharks swim across the screen and children are instructed to tap the screen whenever they see a Fish (‘catch the fish’) and refrain from tapping when a Shark appears (‘avoid the sharks’). This game takes approximately 5 minutes to complete. Scores are presented on the final assessment screen. For more precise research applications, there are options to have the item by item data sent to a user-specified e-mail address or database.

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.
