As an example, I believe a chef is what we would call a skill level B, for those A, B, C or D, meaning that it's a technical job. Skilled trades usually call for a college diploma, training or apprenticeship. If you ask me, from a NOC perspective, I would not necessarily say that is a low-skill trade. I would say that's a profession for which you typically require up to two years of formal technical training.
Likewise, again on the caregiver, when we say skill, the definition of skill is where we get caught up here, I think. The definition of skill is the typical education or training required.
Maybe there's something here about how that's communicated and explained, in terms of what we mean by skills, because right now it's focused around education and training.
