A specialised knowledge and counselling organisation (Videns- og Specialradgivningsorganisation, VISO) within this board provides advice to municipalities, institutions and citizens across the country in the area of special needs education and rare special needs free of charge. Examples for the areas of expertise include, autism, cerebral palsy and diffuse brain injuries, hearing loss, and self-harm. Typically, teachers and school leaders should in the first instance discuss their needs with their local educational-psychological advisory service (PPR), which should then decide if VISO should become involved.
