How it works
What we offer

Gamified Executive Function Assessment
EFSim is a web-based, gamified tool designed to assess executive functions such as attention, memory, planning, and impulse control. It simulates a realistic home environment where users complete everyday tasks, making the experience engaging and naturalistic rather than clinical.

Objective and Clinically Valid
Unlike traditional questionnaires, EFSim provides objective, data-driven insights into cognitive performance. It is CE-certified and backed by research, offering a sensitivity of up to 88% and specificity up to 92% for detecting ADHD-related executive function deficits.

Fast and Accessible
The test can be completed online in a short session using any computer, either at home or in school settings. This accessibility helps reduce long waiting times for ADHD assessments and provides families with actionable insights quickly.

Dual Reporting for Clarity
EFSim generates two instant reports: one for healthcare professionals with detailed cognitive metrics, and another for parents or schools with practical guidance for immediate support. This dual approach ensures clarity and next steps for all stakeholders.

Supports Early Intervention
By identifying executive function challenges early, EFSim helps families, schools, and clinicians take proactive steps. This can include tailored educational strategies, behavioural support, or referral for a full ADHD diagnostic assessment if needed.

Reducing Barriers to Care
EFSim aims to streamline ADHD pathways, cutting down inappropriate referrals and reducing waiting lists. It empowers parents and professionals with actionable data, improving the overall experience and outcomes for children and young people.
