Preference Assessment Inventories are used to determine what children value the most. Items that are determined highly motivating can then be used when implementing a Work/Reward system. When printed, these Preference Assessment materials fit a 3 inch binder! Materials include Pre-Filled Preference Assessment data sheets for 180 common reinforcers across 6 categories (Edible Reinforcers, Tangible Reinforcers, Sensorimotor Reinforcers, Social Reinforcers, Activity Reinforcers, Community Reinforcers & Create-Your-Own). Corresponding pictures and text are included. Storage pages are available for maintaining an organized assessment system. Assessment materials can be used with children that are able to self-report by presenting objects or pictures and asking them to rate the items (I don't like it, I like it, I love it!). Assessors familiar with the child can complete the assessment for students not yet able to self-report. Choice mats are provided for giving children reinforcer options. This system provides everything you need to assess and record student preferences as often as needed, year after year!
