The rationale is that the system was designed in 2015 and hasn't actually been redesigned since. The points ranking system measures for very basic qualities. It measures for age and for Canadian work experience. When you put a NOC code as well, that is not really being divided up by the level of TEER, so a TEER 1 and a TEER 3 NOC code under Canadian experience class would be ranked the same level. You don't get extra points for having a higher skilled occupation under the Canadian experience class or even in the trades draws. The cooks and the chefs would actually be ranked equally under the trades draw because they both have work experience.
