EFSim (Executive Function Simulation) is a clinically validated, gamified digital assessment tool designed to evaluate attention and executive function in children. EFSim is a test classified as an MDR Class IIA medical device, it uses a browser-based simulation of everyday life to capture objective, reliable behavioral data. The tool generates comprehensive, automated reports that help healthcare professionals and educators identify specific neurodivergent challenges while bypassing the limitations of traditional subjective questionnaires. Already integrated into UK and Finnish school health systems and specialized hospital units like HUS, EFSim is also expanding its clinical footprint across the UK’s NHS networks. Ultimately, EFSim accelerates access to early intervention, helping families and professionals establish efficient, child-centered care pathways.
