Their main focus is on equalisation of opportunity in the labour market, having a comprehensive and coherent syst

16、 disability for children,Measuring capacity and/or performance In some activity domains, seeing and hearing, walking or climbing, parental responses should be valid and reliable. However, questions relating to the childs behaviour (particularly for older children) may be less reliable. Parents may n

The consequence of this interaction and inter-dependence is that a survey about disabled children requires as much if not more information about the family structure, behaviour and attitudes.,14,Defining disability for children,Influence of the educational environment Schools as well as familie

All the problems are recognised; the solutions are known but widespread. Need a synthesis of all the work done so far to arrive at a feasible strategy. The ICF-CY is the overarching topology to bring it all together in a meaningful way.,
