International Standard Classification of Occupations

The International Standard Classification of Occupations  is an International Labour Organization (ILO) classification structure. The current version, known as ISCO-88, is the third iteration, following ISCO-58 and ISCO-66. There is an updated version of the structure being prepared for release by 2008.

The ILO describes the purpose of the ISCO-88 as: "a tool for organising jobs into a clearly defined set of groups according to the tasks and duties undertaken in the job. It is intended both for statistical users and for client oriented users. The main client oriented applications are in the recruitment of workers through employment offices, in the management of short or long term migration of workers between countries as well as in the development of vocational training programmes and guidance."

ISCO-88
The ISCO-88 divides jobs into 10 major groups, with each group further organized into sub-major, minor and unit (not shown) groups.
