Institut der Wirtschaftsprüfer in Deutschland e.V. (IDW)

Founded in 1932, the IDW is an incorporated association of over 13,000 German public auditors and auditing firms. The IDW represents profession's interests both within Germany and internationally, undertaking technical work relevant to the fields in which its members are active. Members have access to a wide range of services and also, through the IDW Academy, an extensive program of education and continuous professional education. Membership of the IDW is voluntary, and it is gratifying that more than 85 % of the German public auditor profession are members of the IDW.

German public auditors are members of a highly esteemed profession; the only profession authorised to perform statutory audits of German companies legally defined as large. However the services German public auditors offer are not limited to auditing, but extend from tax advice, including legal representation in tax matters, to providing expertise in any area of business management, insolvency, trusteeship, advice on financial matters and under certain circumstances even legal advice.
Before they are officially appointed, candidates must gain appropriate professional experience before passing stringent professional examinations covering a range of subjects essential to the profession and finally swear the professional oath before the German Chamber of Public Auditors [Wirtschaftsprüferkammer]; membership of which is compulsory.
