The National Diploma (French: Le Diplôme National du Brevet des Collèges) is a diploma given to French pupils at the end of 3^e (year 10 / ninth grade), This diploma is awarded to students who are or were within French cultural influence, including France itself, Morocco, Tunisia, Lebanon, Syria and Algeria, the first two having been french protectorates, while the middle two were under French Mandate after World War I whilst the last was a French territory from 1830 until its independence in 1962. Pupils outside of France who study in French schools belonging to the Agency for French Teaching Abroad network also sit this exam.

To be awarded a diploma, pupils must acquire the seven key competencies of the "Common Core of Knowledge and Skills" and score a minimum of 400 points (out of 800). These points are awarded via tests in each subject except in history-geography-civics (continuous assessment: contrôle continu) and in a final exam at the end of 3^e. Also starting from 2008, pupils must acquire the A2 level of the Common European Framework of Reference for Languages in a foreign language (English, German, Spanish, Italian...). In other countries, primarily the UK, United States, Canada, and several ex-Yugoslav and Asian countries, the equivalent period covered by the diploma is middle school.
