The document is a quiz about the "Please wait" procedure used in PECS (Picture Exchange Communication System) training. It asks 10 multiple-choice or true/false questions to test the learner's understanding of: 1) The ultimate goal of using Please wait, 2) When to start Please wait after PECS phases, 3) How phase 1 of Please wait is structured, 4) When and where to collect data on a learner's progress with Please wait. The quiz appears to evaluate if the learner understands the key components and proper implementation of the Please wait procedure at different phases.
