Nerd Tools

NERD Tools Foundation was established in 2018 by a group of scientists with the aim of developing and promoting Educational Neuroscience Research.

NERD seeks to develop diagnostic and intervention tools which could also act as assistive technological aids for learning.

First Specific Learning Disability (SLD) Toolkit in India

NERD Tools foundation has developed a Specific Learning Disability (SLD) Toolkit for assessment of Dyslexia, Dyscalculia and Dysgraphia. These tools are based on latest research in neuroscience. The tools assess age appropriate core abilities and skills in children and are curriculum agnostic. The tools are culturally and contextually appropriate for India and will be available in multiple India languages. Once assessed, an intervention regime can be formulated specific to a child’s type and degree of disability.
