1. Middle School: This is the most common translation. In France, "le collège" refers to the secondary school for students aged 11-15.
2. College: This translation is less common, but it can be used to refer to a college in the broader sense (similar to the American "college" or the British "further education college"). This is less frequent because "université" usually refers to a university in France.
So, to understand the meaning of "le collège" in English, you need to consider the context. If you see it in a discussion about education and the age of the students is 11-15, it most likely refers to middle school. If the context is broader and involves higher education, it could refer to college.
