Sometimes called a professional portfolio or work portfolio. The defining feature is reviewable artefacts, not bullet-point experience.
A portfolio is a curated collection of a person's work, organised so a reader can see what the person has actually done. In creative fields the convention is well-established: designers, photographers, writers all maintain portfolios. In business, technical, and analytical fields the convention is newer but increasingly expected at the entry level.
The defining feature of a portfolio — what separates it from a CV — is reviewable artefacts. A CV claims experience and skills in summary. A portfolio shows the actual work: the deliverable, the reasoning, the rubric assessment, the iteration history. The reader can form their own judgement.
Ewance is structured around portfolio building. Each challenge a student ships becomes a portfolio entry — the brief, the deliverable, the rubric assessment, the verifiable credential. A student picking up challenges across their degree builds a portfolio that carries the first-job application instead of being assembled the week of graduation.
The fastest way to know whether challenge-based learning fits you is to ship one.
