B1 is the level that counts on a school record
B1 is the first DELF level a French secondary school, a lycée exchange or a university foundation year will really look at. It is also the point where a teenager can spend a school year in France without the language being the main obstacle.
The topics grow up with the candidate. École & Études takes up 60 of the 512 cards and Métiers & Travail 42, because at B1 the exam asks what they want to do afterwards and expects an argued answer.
From describing to arguing
At A2 the question is what you did. At B1 it is what you think, and why. That needs a different kind of word: le développement durable, lutter contre le gaspillage and un bénévole are the vocabulary of holding a position on something.
Le passage à l'âge adulte shows the shift well. It is not an object or an activity, it is an idea, and the B1 oral is built out of ideas like it.
What the Junior B1 exam looks like
Four papers again, 25 points each, 50 to pass, 5 minimum per paper. The writing paper asks for around 160 words expressing a personal opinion. The oral finishes with a debate: the candidate draws a short text and has to defend a position on it.
Environment, media, school and volunteering come up most, and that is no accident. They are the four subjects a fifteen year old can reasonably be expected to have an opinion about.
