The Watson Institute has three LEAP preschool locations in Pennsylvania. A number of other schools in the US have now adopted the LEAP model, either by undertaking the training provided by the Watson Institute or by purchasing the relevant manuals. We have been unable to identify any providers of LEAP in other countries.
Teachers and other professionals involved in LEAP, such as speech and language therapists, will have a range of different credentials and qualifications.
Other people, including parents and other members of the family, may also be involved. They do not need any formal qualifications, although most will have studied the materials published by the Watson Institute or attended one or more of their courses.
However, Strain and Bovey (2011) reported that it took two years before most teachers were able to implement LEAP as it was designed to be used.
