The IDL Story

IDL was devised in the mid 1980s by educators working with the Starcross Educational Research Association. In 2012 a programme was funded by the Big Lottery called Lifting Barriers.

This allowed IDL to be developed for use within a school environment in conjunction with SENCO leaders. Over a three year period IDL was placed in to 120 primary and secondary schools across the North West. IDL was required to show an increase in reading and spelling ages along with an increase in confidence and self-esteem for those pupils with dyslexia or dyslexic type difficulties.

The results showed an average increase in reading and spelling ages of 11 months after only 26 hours use.

In March 2026, IDL was integrated into our parent company, Ascentis, an educational charity and leading awarding organisation.
