German schools of social work developed in the imperial period, and in 1917, they came together to form 'the Konferenz Socialer Frauenschulen und Wohlfahrtschulen Deutschlands' in order to bring about some uniform standards. The first state regulations were issued in Prussia, followed by new regulations in 1920 and similar decrees in other German states. In 1930, The Ministry of Social Work published proposals for a standard syllabus for all schools of social work, with a Diploma granted at the end of a probationary year.
