Development and standardization of the DALI-DAB (dyslexia assessment for languages of India - dyslexia assessment battery).

A majority of Indian schoolchildren are biliterate in that they acquire literacy in at least two language systems, necessitating dyslexia assessment in both. The DALI-DAB assesses risk for dyslexia by evaluating reading ability and literacy-learning potential through a battery including literacy tests (letter and word reading, spelling, nonword reading, reading comprehension), and mediator skills (phonological awareness, processing automaticity and executive fluency, oral language) in multiple languages. DALI-DAB was developed in three languages - English, Hindi, and Marathi - and standardized on a sample of 1013 children.
