Offer
01
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.
03
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.
05
Supports Early Intervention
By identifying executive function challenges early, EFSim helps families, schools, and clinicians take proactive steps. This can include tailored educational strategies, behavioral support, or referral for a full ADHD diagnostic assessment if needed.

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 upto 92% for detecting ADHD-related executive function deficits.
