Boundary settings are a type of environmental support for students with ASD. Basic boundary markers which establish physical space for specific activities such as break time areas, and reading areas help students differentiate expectations across settings, especially when one area is used for different activities (this is very common in classrooms around the world). For example, if two or more tasks must be completed at the same work space or work area, using a colored tablecloth can help distinguish one activity from another. Reading could take place at the table and then it could be covered with an orange tablecloth when it is time for math. Additionally, sectioning off an area on the floor with colored tape, rugs, or anything else that would indicate where a student is expected to be during any given activity is an effective environmental support. This type of marking or labeling is simple and seems to be a minor modification, but in fact, it is highly effective for working with students with ASD. These modifications can reduce students’ confusion and increase clarity by identifying expectations.
It is important to note that simply applying these types of environmental supports without explicitly demonstrating them to the student and explaining what they are intended for will likely not result in the desired outcome. It is almost always necessary to show the student how they are intended to be followed for the markers and boundaries to be effective. Often times, showing or demonstrating to the students how the boundaries and markers are to be followed needs to be done repeatedly and over time.
Finally, when boundaries and markers begin to show effectiveness with students with ASD, rewards for appropriately following the supports should be utilized. That is, when a student correctly follows them they should be provided with social praise or other types of rewards.
