Ms. Barrados, in fact, you are there to enforce the language provisions. That's your mandate. And you were only able to get the same mark, C, on language of work. There's no excellence at that level. I don't want to take anything away from the fact that there are champions in the various departments, but that, at some point, is the target.
You may be disappointed at getting a C, but we can ask ourselves the question: why were you disappointed after seeing the results? That means that some things didn't go well at your department in recent years for you to come up with those results. You're not even able to achieve a level of excellence on language of work, and it's you who must enforce the language provisions in the public service.
Instead you should examine your conscience and realize that some things were taken lightly, set aside or not carefully examined. Something's wrong. Something besides apologizing has to be done after that; you have to examine your conscience and say that there are problems specific to the system that we ourselves are managing.
