The main providers of the DIR method are the parents and other informal carers who undertake the Floortime exercises. They do not need any formal qualifications, although most will have studied the materials published by the Interdisciplinary Council on Development and Learning or attended one or more of their courses.
The other providers may include a range of professionals, such as speech and language therapists, occupational therapists and educators.
In theory, any parent or carer can implement the DIR method for themselves, once they have bought and read relevant training materials or attended relevant training courses provided by the Interdisciplinary Council on Development and Learning.
Professionals, such as speech and language therapists, occupational therapists and educators, will have a range of different credentials and qualifications.
The Interdisciplinary Council on Developmental and Learning website also provides details of approved clinicians who can provide assistance with the DIR method within the USA and some other countries.
