Bruno Bobkiewicz, principal of the Berlioz school campus in Vincennes and secretary general of SNPDEN-UNSA, answers questions from Alexandre Le Mer. Together, they are interested in the difficulties that the creation of level groups in French and mathematics would cause for 6th and 5th grade students.

“I’m afraid of a two-speed school,” says Bruno. ‘I don’t know how to make it work,’ says Alexandre.
