The Lidcombe Program was developed in Australia and is now used by most speech-language pathologists there. The Lidcombe Program Treatment Guide has been translated into a number of languages, and these translations can be downloaded from this website. There is an international Lidcombe Program Trainers Consortium, with members in several countries. The Consortium has provided Lidcombe Program training to thousands of speech-language pathologists in those and other countries. You can read about the consortium at this website.
