The Department of Work and Pensions disability assessment is a measure of physical and mental capacities under clinical or controlled conditions from occupational health in respect to employment performance. The test for disability is capability as ""the mental or physical impairment with an adverse effect on day-to-day activities"" as social performance. The assessment of capacity is used in a home based disability assessment under s.47 NHS and Community Care Act 1990. For a parent, a parental disability is the mental or physical impairment with the adverse effect on the day-to-day activity of giving the child the care it would be reasonable to expect a parent to give a similar child (s.31 Children Act 1989). Whatever their mental or physical impairments parents should be given the necessary disability support to care for their children to maintain a reasonable standard of health and development. (s.17(10) Children Act 1989). For those with parental responsibility mental capacity to make decisions in own best interests is extended to parental capacity to make decisions in the best interests of the child by Working Together to Safeguard Children. The s.47 disability assessment is extended by Part III and s.8 Part 1 Schedule 2 Children Act 1989. Part III Children Act 1989 includes s.17 and the local authority duty to safeguard and promote the welfare of children by the provision of services for the families of children in need. The services include advocacy services for advice and assistance in decision making when exercising the authorities of parental responsibility. This was another clear intention of the act described in the Department of Health Introduction as ""the belief that children are best brought up in the family with both parents playing a full part. the local authority duty to provide support for children and families."" The s.47 disability assessment is to support mental health care in the community and is conducted with a view to a possible deprivation of liberty for those who lack the capability to care for themselves in the community under Schedule A1 Mental Capacity Act 2005. The decision is made after a Multi Agency Risk Assessment Conference known as MARAC. In the case a parent who is not capable of meeting the child's needs then the local authority can intervene with a court order under s.31(2) Children Act 1989. To do so they must meet the public law thresholds that the child is suffering, or likely to suffer, significant harm attributable to the care it would be reasonable to expect a parent to give, the same criteria as for parental disability support.
