It is very common these days when I walk into a house with a child and parent who has lots of adaptive equipment and needs guidance on how to put all the pieces together utilizing the brains of the entire child's Individualized Family Support Team (IFSP) members. In the assistive technology world, we say that the best AT evaluation happens when the AT specialist collaborates with all of the client's therapists (occupational therapist, physical therpist, speech pathologist, parents, social workers, etc.).
I find that the SETT Framework created by Joy Zabala to be the best AT assessment in the field. It take as a real world look at the child's global abilities through a rubric. Collaboratively, the team determines what sort of equipment (i.e. tools) would be appropriate for the child to complete a task(s) in his/her daily routine.
