If asked to name a common intervention strategy that is useful with all individuals with autism spectrum disorder (ASD), adults familiar with the disability would likely respond with “the use of a schedule.” Schedules are considered to be a common positive programming element that one should automatically consider providing for a person with ASD. Often care providers or staff wait until behavioral issues require the introduction of a schedule and the subsequent training regarding its use. Other times, people will fade out the use of a schedule because they insist that the student or their child knows his/her schedule and does not need a physical representation; often this action must be reversed. Even though schedules themselves look rather innocuous and mundane, they represent a powerful intervention tool. This article will review the important functional, cognitive, and physical features of schedule use. It hopefully will be easier to support this strategy when one understands various aspects of deliberate design.
First, let’s explore the parameters of a typical schedule. Wait! There is no such thing as a traditional looking schedule. Schedules vary in appearance according to student ability, need, and the design preferences of the person preparing the schedule. A schedule typically displays, via a visual format, information about forthcoming activities. Student schedules can look different from one another along several dimensions.
First, developers can organize schedule information in a simultaneous or sequential display. In a simultaneous display, a number of event entries can be seen at once, but the person is directed to access the information, as needed, in a sequential order from a vertical (top to bottom) orientation to a horizontal (left to right) display (see illustration a and b). An alternative for students who would be overwhelmed by seeing multiple pictures on a display is the sequential display. The sequential order of activities is signaled by the physical arrangement of information that only displays one item at a time. Often times, this is a series of cards on a ring or a single item per page in a notebook (see illustration c).
Schedules can also vary by symbol representation. Objects, pictures, pictures with words, or just text might be used to represent an activity or location. The pictures might be photographs, hand drawn depictions, commercial basic line drawings (e.g., Mayer-Johnson PCS Picture Communication Symbols), or more detailed commercial drawings such as found on a PECS vocabulary CD available through Pyramid Educational Consultants, Inc. Size and clarity of items may also vary between displays. Having symbols that are easily recognized would seem to be important for motivation and comprehension of meaning.
Pictured symbols may appear on a singular flat surface display that might be taped to a desk, wall, or be tucked into a pocket inside a notebook. Pictured symbols could also appear on individual cards that fit into a slot chart, notebook, or attach by Velcro to a hanging display. The pictured items may be laminated or covered with clear contact paper. If objects are needed as symbols, they also might be attached with Velcro to a display or they might be individually put into a series of horizontally or vertically connected open faced containers.
Displays may also contain pockets for objects or pictures that represent completed activities. The pockets might be on the front of the display or, in some cases, on the back.
Students need to be taught how to use a schedule (procedural information). Adults who design schedules should have cognitive objectives that are embedded in the schedule design. Through experience, some of the students will cognitively recognize what the schedule can do for them; others may use it only as part of a taught routine that directs their movement from one location to another. It is not always easy to separate out the advantages for the adults vs. the student. The true power of a schedule is measured by the following underlying accomplishments. For the student, a schedule:
