"Troisième" is the name of the third year of secondary education in the French education system, typically for students aged 14 to 15. It is an important year as it prepares students for the national examination called the Diplôme National du Brevet (DNB), which assesses their knowledge and skills in various subjects. During Troisième, students study a range of subjects, including mathematics, science, history, and literature. This year also includes a focus on career guidance, helping students explore their future educational and vocational options as they prepare to transition to lycée or vocational training.
