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.
Association of Social Workers
The Association of Social Workers (ASW) was the main professional body for non-specialised social workers in the United Kingdom. It was established as the British Federation of Social Workers (BFSW) in 1935 and changed its name in 1951. From 1949 it opened its membership to all social workers and from 1951 promoted itself as the body to join to work towards a unified profession.
