ISCO-68 stands for the 1968 International Standard Classification of Occupations maintained by the International Labour Office. ISCO-68 has been an extremely useful instrument for harmonizing detailed and crude national occupational classifications to a common key. In 1990, ISCO-68 was replaced by a 1988 edition of the ISCO, which we designate ISKO-88. However, ISCO-68 is in some ways preferable to its successor. In particular, it provides better distinctions among small self-employed and agricultural workers than does ISKO-88. Moreover, many surveys rely upon national census classifications that often closely follow ISCO categories, which before the 1990/91 round of censuses meant ISCO-68. In such instances, mapping national occupation codes to ISCO-68 categories generally provides a better fit than mapping them into ISKO-88 categories. The ISMF project thus uses both ISCO-68 and ISKO-88 as tools for standardizing occupations. The ISMF-project provides the following conversions for public use:
