As school is back in session, what is the most important piece of advice you can offer caregivers and teachers of autistic students?

Autistic students, and students in general, have difficulties with change and unpredictability. This makes the transition from breaks back to school difficult. To make this transition easier and more enjoyable, it can be helpful for caregivers and teachers to provide spoken and visual timelines (or stories for younger students) of what they will be doing before they begin and throughout the transition.
