I will tell you what we mean by “partial bilingualism“. The term is actually a literal translation. In fact, it would be exactly half of a school day. Fifty-fifty, in other words 50% French over the six to seven years of school. It varies according to subject matters. For instance, it could be over the course of a week. Each school board or school has its own specific model.
