In 2021, EsadeEcPol, in collaboration with the "Empieza Por Educar" Foundation (ExE), launched "Menttores", an online educational reinforcement program aimed at students from vulnerable backgrounds in response to the challenges posed by COVID-19. Over 8 weeks, 356 students aged 12-15 from 18 educational centers in Madrid and Catalonia benefited from three weekly tutoring sessions, each 50 minutes long, taught by paid-for, qualified math teachers who passed a rigorous selection and training process. Through a "Randomized Controlled Trial" (RCT), it was shown that the program achieved a significant increase in math grades, reduced the likelihood of repeating the school year, and additionally, fostered the aspirations and commitment of the students.
