Despite giving adequate processing time when expressing behavioral expectations or schedule changes, students may continue to struggle with going from hearing to doing. While the learner may hear the words you are saying they may not be visualizing them accurately and hence are unable to follow through. Save your breath in repeating directions over and over. If the words don’t stick, make a pic.
As a rule of thumb, if there is anything you have to consistently tell your learner five times or more in a day, then make a picture of it. By placing that visual in their environment and then pointing to it when the need arises for priming or redirection you begin to help the learner to take cues from the environment around them instead of from a person. This sets them on the path to independence for it is from the real world that independent people receive cues for behavioral expectations every day. 
The simplicity of the behavioral expectations strategically placed on the Ultimate Access Card are a cornerstone to the tool’s success. Even the specifically designed art itself is exact to the point, eliminating any room for confusion and optimizing understanding for the learner. In some cases students may need to see themselves in the picture. We are then required to take a picture of them engaging in the proper behavior and posting it for them to see.
So what expectations are you repeating over and over? What visuals do you need to create and where do they need to be placed in your room? By using visuals we are teaching our students to read the world around them rather than it being read to them. And those that can read the world around them will have a much higher likelihood of their story being one of independence.
