Skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. Skill level is measured operationally by considering one or more of:

• the nature of the work performed in an occupation in relation to the characteristic tasks and duties defined for each ISCO-08 skill level;
• the level of formal education defined in terms of the International Standard Classification of Education (ISCED-97) (UNESCO, 1997) required for competent performance of the tasks and duties involved; and
• the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
