IDL provides specialist award-winning literacy and numeracy interventions at a primary and secondary level. IDL Literacy supports learners with dyslexia and other learning difficulties to increase their reading and spelling ages. The programme was specifically designed for those with dyslexia but can also be used effectively as a school wide literacy solution. IDL Numeracy is a maths resource that helps to improve ability for low-attaining learners in mathematics. It includes a fully graded course to support the National Curriculum for both Key Stage 1 and Key Stage 2 maths. We also offer free dyscalculia screening software to all schools.
