High-dosage tutoring is a pedagogical approach that provides students with individualized support to accelerate learning. Through this approach, students receive targeted tutoring in small group settings. In these groups, students practice and master content knowledge and skills, build academic confidence, work collaboratively with their peers, and develop lasting relationships with their tutors. 

Tutoring delivered in high doses is one of the most effective evidence-based interventions for math and reading. There are many ways to implement a high-dosage tutoring model, and while aspects like group size, cadence, and duration are not the same across all models, many share the following best practices: 

  • Small groups – A 1:2 or 1:3 tutor-to-student ratio enhances student voice and further individualizes instruction and targeted interventions. 
  • High Dosage – The most effective programs implement sessions routinely for at least 90 minutes a week over the course of three sessions year-round. 
  • During school hours – Tutoring happens during the school day during a designated and protected time to increase attendance and levels of engagement. 
  • Rigorous curriculum – Models either provide their own rigorous tutoring curriculum or work collaboratively with classroom teachers to develop complementary materials that focus on skill-building.

What Makes This Innovative?

High Expectations with Unlimited Opportunities for All

Offering targeted, additional academic support ensures expectations remain high for all learners and increases opportunities for learners to meet those expectations.


Small group instruction and tailored tutoring materials that are closely aligned to a core curriculum ensure every student receives support that fits their needs.

Connection & Community

Small group instruction and frequency of sessions enable tutors and students to develop close, trusting relationships.
