With Common Ground Tutors, students are grouped by skill level into small cohorts of 4 students and receive personal attention during their 45-minute tutoring sessions, three times a week. Students learn best when they develop a long-term relationship with a tutor who knows them well, cares for them, and gives them the personal attention they need. This is key to academic achievement, as well as social-emotional learning. SEL and positive psychology are core guiding principles in all our work, as research shows that SEL is closely linked to improvement in academic performance.
