In pre-Reformation England religious orders undertook the main share of what is in modern parlance known as social or welfare work, that is, the care or relief of the sick, the fatherless, the needy and the aged. After the Reformation this kind of work was apt to be neglected, or undertaken in a somewhat inhuman spirit under the auspices of the Poor Law. By the eighteenth century, however, the country’s conscience began to be stirred by the sight of so much misery, and hospitals, orphanages and rescue homes were founded by public subscription or private philanthropy. This good work continued throughout the nineteenth century, inspired generally by religious principles and in the main sponsored by various religious organisations. By the end of the century, however, a more scientific approach to social work began to manifest itself. The Charity Organisation Society was founded to discourage indiscriminate almsgiving and substitute an organised system based on family case-work, and the Webbs, although they disapproved strongly of C.O.S. methods, were among the most vociferous champions of a more scientific approach to social problems.

This scientific attitude has in our century led to the transformation of the social worker from a well-meaning amateur, usually with a strong sense of vocation, into a trained professional. Most social service posts advertised today require of applicants a Diploma in Social Science such as is granted by universities on completion of a course both academic and practical. The academic part, includes study of such subjects as constitutional and economic history, economics, political theory, local government and psychology.
