Other schools in many other countries including France and Japan have the same or very similar name to Jean de la Mennais.

Jean de la Mennais is often regarded as one of the most prestigious secondary institutions on the South Shore of Montreal.

Unlike many other top private schools in Québec, Jean de la Mennais doesn't necessarily take the best candidates for admission.

Since one of the main goal of the Brothers of Christian Instruction is to let education be available to everyone and especially to the working class, the school admits students more randomly.

In their senior year (secondary 5), students can choose optional courses to match with their interest: journalism, psychology, advanced mathematics, physics, chemistry, law, theatre, history, enriched science topics etc.
