The content and social validity of an educational planning tool named COACH (Choosing Options and Accommodations for Children) were explored through two studies. Study 1 presents questionnaire feedback from six groups of experts (N = 78) in the field of deaf-blindness and multiple disabilities regarding the purpose, philosophy, content, process, and presentation of COACH. Study 2 presents social validation feedback from parents whose children are deaf-blind and have multiple disabilities regarding a set of valued life outcomes included in COACH. The combined results of these studies provide initial validation that COACH is congruent with exemplary practice and offer consumer-based suggestions for its potential improvement.
