TS 12644

TS 12644 is a occupational classification standard for elementary occupations, setting out how these jobs are grouped, coded, and defined. Anchored to ISCO 88, it provides a common terminology that supports consistent recording and comparison of labour-market data across organisations and datasets.

How occupational groupings are organised

The standard focuses on the systematic classification of elementary occupations that share broadly similar work content. In practical terms, coding helps prevent the same job from being recorded under different names in personnel systems, statistical returns, and employment analyses. The emphasis is on arranging occupations into comparable categories rather than describing every job in operational detail.

Why definitions matter in labour statistics

In general technical context, occupational classifications separate jobs by factors such as tasks performed, skill requirements, education level, and work complexity. Elementary occupations are commonly understood as jobs involving routine or basic tasks, but that concept here serves classification purposes rather than legal or employment-status claims. The value of the standard lies in terminological clarity and statistical consistency.

• Conceptual alignment with ISCO 88
• Grouping, coding, and defining elementary occupations
• A shared language for labour-market records and reporting
• Support for administrative, HR, and statistical classification work
