1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.International Standard Classification of Occupations (ISCO)

Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.This classification is almost identical to the ISCO08 from the International Labour Organization (ILO) (except for the omission of two codes, see question 3c for further explanation).
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)The classification structure is identical.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.One minor group (224: paramedical practitioners) and subsequent unit group (2240: paramedical practitioners) from the ISCO08 is not used in Belgium, because these occupations don’t occur in Belgium and the title of this code could be confused with what we call ‘paramedische beroepen’. For this reason these codes were omitted.
3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)For some surveys data on 3 digits are provided (LFS: Labor Force Survey, Silc: Statistics on Income and Living Conditions, SES: Structure of Earnings Survey, AES: Adult Education Survey)

For other surveys, like HBS (Household Budget Survey) and Census one digit is delivered.
