There is this school where Iam a member of Board of Management. We receiveved a new principal last year who introduced something new to the school- rewarding best improved (not top performers) student in academics and discipline. This sounded strange but it has surprised most in just one year. Even those students that teachers thought were incapacitated in various ways have shown tremendous improvement. Recognising individual efforts lead to development of positive attitude by both teachers and students which is very important in creating an inclusive school. 

I also recall one incidence that happened 20 years ago when I was a class teacher in high school. This mother brought a small small girl to be admitted in Form one ( she was 14 years but her growth hormones had stalled and she looked 6 years old or so ). They came with an equally small desk and chair ( they were certain the girl would not get an appropriate sitting arrangement). On admission, the mother insisted I take her to class with her daughter and she carried the desk and the girl carried the chair. They went and placed it at the front of the class and just next to the teachers table. Talk of being assertive! Nobody dared make fun of that girl for the four years she was in that school. Teachers and students respected and included her in all school activities. Parents play a major role in the success of inclusive ethos and culture.
