‘UDL is a philosophy of education intended to provide access to learning and success for all students (Sokal & Katz, 2015). The Centre for Applied Special Technology (CAST) model of UDL espoused by Rose, Gravel, and Gordon (2014) is based on three principles that include (a) multiple means of engagement, (b) multiple means of representation, and (c) multiple means of action and expression. Because UDL is principle based it is inherently flexible and adaptable to local classroom contexts and circumstances’ (Loreman, 2017: 4).
