This database includes an initial set of organizations that offer tutoring, technology platforms or academic interventions along with relevant information if available.  This is not meant to be an inclusive list, but a starting point. We welcome additional organizations to join the database by completing this form.

  • Tutoring programs are those organizations that offer one-on-one and/or small group tutoring directly to students, either in-person, virtually, or through both modes of delivery. 
  • Technology platforms are technology platforms that facilitate tutoring programs.
  • Interventions offer materials (e.g., an instructional scope and sequence, placement assessment, progress monitoring tools) that are used by a tutoring program, but do not offer tutoring directly.  

This database is intended for Districts, States or nonprofits to identify potential tutoring partners, for potential tutors to identify potential employers and for tutoring organizations to have a clearer understanding of the landscape and to identify interventions that might be useful to their programs, if needed.

Please note that some of these programs are also listed on ProvenTutoring.org where you can find additional information on relevant research studies and costs.

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. Additionally, a whole-child educational philosophy is key to our approach. We begin each session with artistic inspiration: a poem, song, movement exercise, and/or story grounded in wisdom. This engages the whole child in learning: “head, heart, and hands.” Students receive a healing education and build a strong holistic foundation for their future.
