There are not a lot of dropouts at the French-language school. However, according to recent statistics, 10% to 15% of students in regular schools have special needs. In the French-language school in the Yukon, it is 37%. Does that mean they will drop out? I don't know. That is one of the reasons why the school board is fighting so hard to get that funding, so that it can help those students.
There is another problem: those students do not have a very good command of French. Their parents may be francophone, or they may have come from an exogamous situation, but, for all sorts of reasons, they did not choose to speak to their children in French from the outset. As a result, the school has a lot of catching-up to do and a number of challenges to meet.
