What is the difference between a declared skill and a confirmed skill?
Short answer
A declared skill is one you state yourself; a confirmed skill is one a manager has verified from real work. Both are shown separately and never mixed.
When you add a skill, it starts as declared — your own honest statement. A confirmed skill is backed by evidence: a manager verifies it from work you actually did, so it carries a stronger signal.
The platform always keeps the two apart. In any match you can see how much of a fit comes from confirmed skills versus declared ones, so employers and workers both know what is proven and what is self-stated.
