Types of skills
Nine categories that are not a hierarchy but different lenses on the same thing
Skill categories do not form a tree. They are different ways of cutting the same set: one asks "how is it proven?", another "does it move to another job?", a third "which domain is it in?". That is why one skill belongs to three of them at once.
The map: three questions, nine categories
Each category is born from a different question. Once you see it that way, the confusion stops.
| The question | The categories it produces |
|---|---|
| How is it proven? | Hard (certifiable) / Soft (visible only in action) |
| Does it move elsewhere? | Transversal, transferable / Vertical, specialised |
| Which domain? | Technical, digital, green, cognitive, social, life skills |
An example that shows the overlap: critical thinking is soft (first question), transversal (second) and cognitive (third). Three labels, no contradiction.
Hard and soft
The best-known distinction, and the most often misread. It is not about difficulty — it is about how the skill is proven.
| Hard skills | Soft skills | |
|---|---|---|
| Proven by | A certificate or a work sample | Observed behaviour only |
| Learned through | Information plus practice | Practice plus feedback |
| Obsolescence | Fast — a technology gets replaced | Slow — listening has no version 2.0 |
| Examples | Accounting, Python, C2 English, welding | Communication, leadership, conflict management |
"Soft" never meant "easy". The pair comes from 1970s US Army training manuals, where hard skills were those performed on machinery and soft skills were everything that did not involve a machine.
Transversal and vertical
The distinction that dominates European policy documents, because it comes from EU terminology for funding training. If you have seen the term in a grant call, that is where it comes from.
- Transversal (or transferable, or horizontal): the ones that follow you when you change sector. Communication, collaboration, problem solving, digital competence, learning how to learn.
- Vertical (or specialised): the ones that only apply inside one field. Radiological interpretation does not transfer to shipping.
They are not the same as soft skills. This is the most common error. Digital competence is transversal and hard: it moves everywhere and it certifies. Conversely, clinical empathy in an oncology ward is soft but fairly vertical — it does not transfer intact to a sales floor.
The categories by domain
| Category | What it covers | Where the term came from |
|---|---|---|
| Technical | Handling the tools, methods and systems of an occupation. | Vocational education. |
| Digital | From basic device use to security and content creation. The DigComp framework defines them across five areas. | European Commission, DigComp. |
| Green | What the transition to a sustainable economy requires — from energy efficiency to circular design. | EU employment policy, post-2019. |
| Cognitive | Memory, attention, reasoning, problem solving. | Cognitive psychology. |
| Metacognitive | Monitoring and regulating your own thinking and learning. | Educational psychology. |
| Social | Behaviours between people and in groups. | School and clinical psychology. |
| Life skills | What daily autonomy and wellbeing require. The WHO defines ten. | World Health Organization, 1993. |
Why the word you use has practical consequences
This is not academic hair-splitting. The word changes three things:
What you find when you search
Search "social skills" and you get preschool and special education material. Search "soft skills" and you get careers advice and corporate training. Same territory, two entirely different libraries.
Whether the training gets funded
European programmes fund "transversal" and "digital" skills. Exactly the same training passes or fails depending on the word used in the proposal.
How it is assessed
A hard skill is judged by examination. A soft skill is not — and anyone trying to examine one with a questionnaire is mostly measuring how well the candidate knows what they want to hear.
Frequently asked questions
What are the types of skills?
They come from three questions. How they are proven: hard and soft. Whether they transfer: transversal and vertical. Which domain: technical, digital, green, cognitive, metacognitive, social and life skills. The categories overlap — one skill normally belongs to three of them.
What is the difference between transversal and soft skills?
They answer different questions. Transversal means it transfers to another sector; soft means it cannot be certified and shows only in action. Digital competence is transversal but hard. The two categories overlap heavily, which is why they get confused, but they are not the same.
What are transferable skills?
Another name for transversal skills: the ones you keep when you change job or sector. The term is used more in career counselling, while "transversal" dominates policy documents and grant calls.
Which skills do employers ask for most?
In the last decade of surveys, transversal and soft skills come first consistently: communication, collaboration, problem solving, adaptability. The reason is practical rather than ideological — vertical technical skills can be taught in weeks after hiring, while transversal ones take years.
