Can teachers' capabilities be defined as an environmental factor that can facilitate people with disabilities?

The roles and functions of assessment is a nodal point in support of the inclusive paradigm, first of all, is linked to the need for individual human fulfilment – that characterizes the ultimate goal of education: an education is only truly suitable for freedom if it is able to guarantee the possibility of realizing the life projects that individuals have reason to choose – secondly, it is necessary to consider the resources that students have at their disposal to achieve the learning objectives. From this perspective, human development do not end with the quantitative dimension of resources, but rather involve complex areas, related partly to social life and partly to the quality of life of individuals.
