Tutoring is currently considered by the Government of Quebec as one of the pivotal measures to prevent and correct the learning delays that children will have experienced following the Covid-19 pandemic. Although it is an attractive and complementary support measure for the preventive action of educators, teachers and parents, its implementation in the school environment presents several challenges. In this conference, we will define tutoring and explain, based on research evidence, the conditions for “efficient” tutoring in schools and the mechanisms that explain these effects on children’s learning, success and school perseverance.
