The challenges of executive functioning refer to an individual’s impaired ability to plan, maintain, and regulate their own actions. These challenges manifest differently in individuals, with some being more noticeable than others.
EFSim provides objective information about executive function skills and offers a solution for the early identification of even hidden deficits.


Neurodevelopmental disorders such as ADHD often co-occur with executive function challenges. However, the severity of executive function challenges varies, and not all challenges stem from diagnosable disorders. The data generated by our software helps identify the level of executive function challenges and tailor support to meet the individual’s specific needs.


Executive function skills are essential in daily life, particularly in situations requiring independent action. Challenges in executive functioning impact not only academic learning but also work and social relationships. Early identification of these challenges and providing appropriate support have a significant impact on a person’s overall well-being.

I especially liked your way of dealing with children. In addition, the moment of giving feedback was really clear and informative.
