Abstract
Systematic preference assessment is the process of presenting sampling trials and observing the person's response. The response to those items is then interpreted as an indicator of preference. The empirical research on systematic preference assessment has greatly advanced the field's understanding of how to identify the preferences of individuals with nonsymbolic and limited symbolic communication skills. The purpose of this paper is to translate this research into guidelines for planning systematic preference assessments that strive to reduce the risk of missing or misinterpreting the person's preferences, as well as increase the social validity of the process and outcomes. We present four guiding questions for practitioners to plan preference assessments: (a) What will be offered? (b) When and where will sampling opportunities take place? (c) Who will present the sampling options? and (d) How will sampling options be presented?
