The primary school became mixed in 1960. The following year the school entered into a contract of association with the state.
In 2008, Rocroy Saint-Léon joined with École Saint-Vincent de Paul and Lycée Petrelle to form the group Rocroy Saint-Vincent de Paul. The new group occupies 3 sites:
- The école Saint-Vincent de Paul at 6 rue de Rocroy (Kindergarten, primary, and year six)
In 2015, the lycée ranked 13th out of 109 at départemental level in teaching quality, and 132nd at national level.[1] The ranking is based on three criteria: the level of bac results, the proportion of students who obtain the baccalauréat having spent their last two years in the establishment, and the added value (calculated based on the social origin of the students, their age, and their national diploma results).[2]
Since 2010, the lycée has always achieved at least 80% of honours[3] and 99% of baccalauréat results.[4]
