Key characteristics of Internal Auditors that are necessary to ensure an effective internal audit function

There are three key characteristics which have been identified for internal audit departments, independence, objectivity and professional care. If internal auditors do not possess these characteristics their ability to perform their role effectively will be compromised.

Independence

The internal audit activity should be independent, and the head of internal audit should report to a level within the organisation that allows the internal audit activity to fulfil its responsibilities. It should be free from interference when deciding on the scope of its assurance work, when carrying out the work and when communicating its opinions.

Objectivity

Internal auditors should be objective in carrying out their work. They should have an impartial attitude, and should avoid any conflicts of interest. For example, an internal auditor should not provide assurance services for an operation for which he or she has had management responsibility within the previous year.

Professional care

Internal auditors should exercise due professional care and should have the competence to perform their tasks. They should have some knowledge of the key IT risks and controls, and computer-assisted audit techniques.
