Leadership for inclusion is a contested concept with competing definitions suggested by many researchers and educa- tionalists. While broad and narrow interpretations of ‘inclusion’ exist, this article focuses solely on the inclusion of learners with special educational needs (SEN) in Irish mainstream schools. A critical literature review of various different leadership typologies, relevant to inclusive education, is presented, from a practising principal’s perspective. This review is used to theorise a hybrid leadership typology, present in schools where children with SEN are included in mainstream classes. The centrepiece of this theoretical model is that any leadership approach, in an inclusive education setting, must be triadic in structure. As a construct, it must be underpinned by a triad of teacher leadership, managerial leadership and values leadership. The argument is advanced that if this triadic structure is to flourish, then a distributed leadership framework is a necessity.
