Sometimes called technical skills or domain skills. Distinct from soft skills by being directly demonstrable on a specific deliverable.
Hard skills are specific, demonstrable skills tied to a particular function — programming languages, statistical methods, financial modelling, design tools, instrumentation, language proficiency. The defining feature is that they have a measurable demonstration: someone can or cannot use Python to wrangle a dataset; someone can or cannot read a balance sheet.
The practical question for an early-career candidate is which hard skills the target field screens for, and how the candidate can demonstrate them. CV self-claims are weak demonstration. A portfolio piece that exercised the skill on a real challenge is strong demonstration.
Ewance challenges target specific hard skills inside the deliverables they require — a financial-modelling challenge produces a model, a data-analysis challenge produces a notebook, a strategy challenge produces a recommendation. The rubric assesses against criteria a practitioner in that domain would apply. The verifiable credential ties the skill claim to the artefact that demonstrates it.
The fastest way to know whether challenge-based learning fits you is to ship one.
