Students with SEBD bring a major challenge to the success of inclusive education. Positive relationships between teachers and students have been found to be a factor vital to the development of students with SEBD. A study reported that students with severe SEBD perceived the teacher student (t-s) relationship in residential schools as better than that in mainstream schools. In Hong Kong, students with SEBD may either study in mainstream schools, or special schools. Some special schools provide residential services. In Thailand, parents can only choose mainstream schools (either public or private) for their children with SEBD. From a qualitative approach, a study was conducted in two Hong Kong special schools (one primary and one secondary) and one private school (with both primary and secondary sections) in Thailand to explore teachers’ perception of the t-s relationship among students with SEBD. The three schools offer residential services. Information was collected mainly from individual interviews with 21 teachers from these three schools. Themes emerging from the analysis reflect that the cultural concerns about the difference between “relationship” and “guanxi” require further elaboration and discussion. Copyright © 2019 ICTEL.
