The purpose of this study was to gather information on the perceptions of sustainability in design held by family and consumer sciences (FCS) students majoring in interior design and apparel design/merchandising. Likert-scale responses were used to explore differences and similarities between students in the two majors. Overall, interior design students' mean scores were higher than those of apparel design/merchandising students, suggesting a greater awareness of sustainable design practices and principles. Understanding students' perceptions provides a basis for considering the inclusion of sustainability and sustainable products and systems in FCS curricula, which may alter professional practice and consumer choices.
