One question separates these two, and getting it right protects both the child and you.
An adaptation is any change you make to help a child access learning. Adaptations come in two kinds, and the difference between them matters more than almost anything else in this workshop.
The test is one question: has the objective changed? If it has not, it is an accommodation. If it has, it is a modification.
Accommodations are yours to make. You can put headphones on a desk tomorrow and tell nobody.
Modifications change what a child is being taught, so they need to be a deliberate decision, recorded, and shared with parents and with whoever teaches that child next.
A modification made quietly, lesson by lesson, becomes a child who has been taught something different for a year without anyone agreeing to it.
Differentiation changes the road. Modification changes the destination. Both are legitimate, but only one of them is yours to decide alone.
This space is just for you. Nothing here is saved or shared, so write freely.
