The Special Educational Needs Coordinator (SENCO) is a teacher responsible for the implementation of policies relating to the inclusion of students with special educational needs (SEN) at various levels of schooling in the mainstream setting. The UK has taken the leading role in SEN coordination since the early 1990s (DFE, 1994). Before 1994, there was no formal requirement for schools to appoint such a teacher. However, the 1994 Code (DFE, 1994) placed a statutory obligation on all schools to identify a specialist teacher to coordinate provision for pupils with SEN, and it described the roles and responsibilities of the SENCO. In the UK, a dominant theme in SENCO research in the past decade has been the extent to which the role is concerned with aspects of leadership and management (e.g., Cole, 2005; Layton, 2005; Rosen-Webb, 2011; Tissot, 2013). The role of SENCOs have been debated in the literature (Norwich, 2010; Oldham & Radford, 2011), specifically concerning whether it should be a specialist role or a more generic management role. An individual's interpretation and enactment of the role of SENCO – as specialist or management, or somewhere in between – depends on the individual (Kearns, 2005) and school-level factors (Blandford, 2013). While the UK schools are exploring effective ways for assuring the effective functioning of SENCOs, Hong Kong followed the footstep of the UK by introducing a similar position in 2015. Through a pilot scheme in 2015, a total of 124 schools, including 65 secondary schools and 59 primary schools, were included. The final evaluation report of the pilot scheme concluded that although there was variation in the roles of SENCOs in different schools, it was clear that they were engaging in more strategic activity as the new role develops (Education Bureau, 2018). In addition, two studies (Poon-McBrayer & Wong, 2013; Poon-McBrayer, 2017) investigating the roles of principal leadership on HK schools' inclusive education reforms found that
