From the Contact website:
A carer’s assessment focuses on you as a parent and your needs. Social services should discuss issues like the help you need, and whether there is anyone else who helps or if you are your child’s only carer. The carer’s assessment should also consider your wellbeing, including health and safety issues, and important commitments like relationships and employment.
W H AT T HE L AW SAYS:
Parents of disabled children (called parent carers in the legislation), young people and young carers have strengthened rights to an assessment of their needs under the Children and Families Act 2014. The Children and Families Act amended the Children Act 1989 (sections17ZD, 17ZE12 and 17ZF). Under it, local authorities must assess parent carers if:
‘it appears to the authority that the parent carer may
have needs for support’, or they
‘receive a request from the parent carer to assess the
parent carer’s needs for support.’
These assessments are called parent carer’s needs assessments. The Act also says that:
A parent carer’s needs assessment must include an assessment of whether it is appropriate for the parent carer to provide, or continue to provide, care for the disabled child, in the light of the parent carer’s needs for support, other needs and wishes. (Children Act 1989
section17ZD (9))
They must also take into account:
‘the well-being of the parent carer’, and
‘the need to safeguard and promote the welfare of the disabled child cared for and any other child for whom the parent carer has parental responsibility.’ (Children Act 1989 section17ZD (10)
This ‘wellbeing’ duty is an important addition. It means local authorities must consider a person’s:
personal dignity and respect
physical and mental health and emotional wellbeing
protection from abuse and neglect
control by the individual over day-to-day life
participation in work, education, training or recreation
social and economic wellbeing
domestic, family, and personal relationships
suitability of living accommodation
contribution to society.
