I would be all for standards being put at the earlier levels, but the problem you would encounter is that not all the students start studying at the same age. There is a difference in standards for somebody who started speaking French--or English, let's say--at home. I think standards should apply to English too.
If there are requirements for English-speaking people in French, there should be requirements for French-speaking people in English.
So it's very hard to establish. There could be agreements between elementary schools, let's say, but in the end, we are talking about working for the government. So if the government is serious that everybody has to be bilingual, to what level do they have to get?
