Research has shown that early intervention is critical in successful remediation of students with Dyscalculia.
Unfortunately there are not many tools available or easily usable for parents, teachers and counselors to help them detect Dyscalculia without going to a provider for a full fledged psycho-educational assessment.
DyscalculiaScreener.org is now available and has a number of tools, free or low cost, to do an early detection to be able to take decisions about further testing or starting with interventions.
