How do technicians differ from craft workers?

Technicians and craft workers can both be highly skilled with their hands, tools, and materials, and they often work side by side on the same site, plant, or product. That closeness makes their classification boundary worth spelling out. In ISCO-08, technicians sit in Major Group 3 at skill level 3, while craft and related trades workers sit in Major Group 7, typically at skill level 2. The difference is not manual dexterity, effort, or pride in work. It is the task centre, the knowledge base, and the kind of output the work produces.

What does a craft worker mainly produce?

Craft work centres on making, building, installing, repairing, and finishing things through a trade. Building trades shape structures, metal trades shape and join metal, electrical trades install and repair electrical systems, food trades prepare food products, and printing and handicraft trades produce printed and crafted goods. The output is usually a physical object, structure, or finished product, and the skill lies in trade knowledge, manual technique, material understanding, and the ability to work to specification with tools and machinery. A craft worker may read plans, measure, cut, join, fit, and test, and the finished work can be inspected directly.

What does a technician mainly produce?

Technician work centres on applied technical knowledge in service of science, health, business, or technology, and its output is often a measurement, a test result, a supported system, a maintained process, or a service delivered within a professional framework. A laboratory technician produces reliable data. An ICT technician produces a working system. A health technician produces a diagnostic image or a prepared medicine. A business associate produces a reconciled account or a completed transaction. The output may involve physical handling, but it is defined by technical and field knowledge rather than by trade production alone. That shift in output, from a made thing to a technical result or supported service, is a key classifier signal.

How does knowledge differ between the groups?

Craft knowledge is trade knowledge: materials, tools, techniques, tolerances, and the properties of what is being made or repaired. Technician knowledge is field knowledge: scientific principles, health procedures, business rules, or systems knowledge, applied through instruments, software, protocols, and documentation. An electrician and an electrical engineering technician may both understand circuits, but their daily knowledge use differs. The electrician mainly installs, maintains, and repairs electrical systems as a trade. The technician mainly supports engineering work through testing, measurement, technical documentation, and system support. Overlap in background knowledge does not erase the difference in task centre.

Where do the groups overlap most?

Overlap is strongest where technology meets production and maintenance. A maintenance worker in a plant may repair machines, while a technician in the same plant may test, calibrate, and monitor them. A printer may operate a press as a trade, while a technician may support the pre press or quality system behind it. A chef may lead a kitchen as a cultural associate role, while a food processing craft worker may produce food goods in a factory. In each overlap, the classifier asks what dominates: trade production and repair, or technical support, measurement, and service within a scientific, health, business, or ICT framework? The answer, based on main tasks, points toward Major Group 7 or Major Group 3.

Why does skill level differ if both groups are skilled?

Skill level in ISCO-08 reflects task complexity and knowledge range, not a general judgement of skillfulness. Craft work at skill level 2 can demand years of training, precision, and experience, and its mastery deserves full recognition. Technician work at skill level 3 is placed higher because its tasks typically require a broader specialised knowledge base, more formal technical understanding, and more judgement within scientific, health, business, or systems frameworks, in addition to practical skill. The levels describe classification structure, not human value. A master craft worker and a senior technician are both experts, in different kinds of expertise, and the classification records that difference rather than ranking the people.

What practical test separates a borderline job?

Ask three questions in order. First, what is the main output: a made, built, repaired, or finished thing, or a technical result, supported system, or professional service? Second, what knowledge dominates: trade technique and materials, or field knowledge in science, health, business, or technology? Third, within what framework does the work sit: a trade specification and workshop practice, or a scientific, clinical, business, or systems protocol? If the answers point to trade production, Major Group 7 is the closer fit. If they point to applied field knowledge and technical service, Major Group 3 is the closer fit. As always, check the specific ILO occupation definition before treating a borderline case as settled, because real jobs rarely fit a textbook in every detail.
