Following the UNESCO initial statement in 1994 that inclusive schools were the most effective way to counter discriminatory approaches and attitudes toward students with a disability, international legislation and policy has evolved to challenge exclusionary practices and focus attention on equal opportunities for all learners. Inclusion in education is now accepted as a basic right and the foundation for a fairer and equal society. In opposition to earlier dual systems of regular and special education, inclusive education presents a changed paradigm in the way that learners with diverse needs are educated. Specifically, generalist teachers are now required to be able to cater to the needs of the most diverse student populations both academically and socially within regular classrooms.
In most regions, there has been a rather slow and lagging change in teacher preparation to support these new developments. It is frequently documented that new graduates and in-service teachers are not well prepared for managing inclusive classrooms and understanding differences among students. Many teachers will say that they require more professional learning opportunities about inclusive education than they currently receive. When teachers are appropriately trained, have positive attitudes toward including students with diverse abilities, and have access to appropriate resources and support, there are many good practices that become evident. Conversely, inadequate teacher education and a lack of suitable resources often inhibit teachers from developing the appropriate beliefs or attitudes necessary for becoming inclusive practitioners.
As the demand for better training of teachers about the inclusion of students with diverse abilities increases, the question that arises is what constitutes best-practice professional learning for upskilling teachers about inclusive education? While a variety of existing practices ranging from in-school support to system-wide approaches are employed globally, identifying which to use must be grounded in the context and specific needs of individual teachers and schools. This article provides a review of the range of models of whole-school methods, including focusing on teacher competencies, developing school and university links, engaging in collaborative scholarship, and establishing professional learning communities. System support is also examined, as this is critical to effective training. The Hong Kong model is cited as a good example of a collaborative government system/university partnership toward upskilling teachers about inclusive education. This model provides a realistic approach to addressing this issue when a longitudinal plan has been implemented to upskill regular class teachers in inclusive education, using initially an off-site training program followed by a school-based whole-school approach that may be of interest to many other systems. Consideration is also given to the training needs of education assistants who work in inclusive classrooms and their roles in supporting students. The importance of lifelong professional learning should underpin decisions regarding what model or approach to adopt, as student and teacher needs will undoubtedly change over time.
