National Insurance number
The National Insurance number is used as a reference number in the Pay As You Earn system, and also by the self-employed. It is also used in applications for Individual Savings Accounts (ISAs), to check that an individual has opened only one ISA in a tax year.
Qualifications for professional social work
Non-registered or non-qualified social care practitioners in the United Kingdom, often referred to as Social Services Assistants, Child and Family Workers or Community Care Assistant or Community Care Workers (not to be confused with domiciliary or care home care workers), are unregistered social care practitioners that often do not hold any formal social work qualification and they must practice under the direct supervision of a registered social worker. This is not the case in Scotland where the scope of registration for social service workers is more advanced.
