There are several reasons for a student to go to Home Base. First, staff can choose to have the student go to their Home Base if they see anxiety and or stress beginning to escalate. Next, Home Base could be used as a check-in and out location where students meet with a support person to go over the day and any challenges the student may face during the day (e.g. A substitute teacher). The final way is for the student to determine that Home Base is where they need to be. The ultimate goal is for the ASD student to be able to self-regulate their emotions and notice when they need there break.
I would know that this intervention was working if he would have been able to make the decision to go to Home Base when he was beginning to have a meltdown. Another indicator could be if the classroom teacher’s suggestion that Home Base would be a good place for them at the moment and they go there without an argument.
