NEW YORK, June 29, 2023 /—, one of the world's largest and most innovative online tutoring organizations, in partnership with its affiliate company, education services giant The Princeton Review, has announced the launch of High-Dosage Tutoring, a rigorously researched solution for accelerating student learning.

Based on data-informed design principles identified by researchers at Brown University’s Annenberg Institute and the University of Virginia, the company’s high-dosage tutoring program features as its hallmarks:

  • 3+ times/week frequency: Tutoring has been shown to be maximally effective when delivered intensively, in high doses.
  • Small-group instruction: Groups of two to four students allow for instruction that is personalized, scalable, and cost-effective.
  • Assessment-based learning: Ongoing assessments enable tutors to tailor instruction.
  • Curriculum-driven materials: High-quality curricula—from The Princeton Review® or K–12 partners—reinforce in-school learning.
  • Consistent, relational learning: The tutor–student relationship enhances accelerated learning and promotes individualized instruction. and The Princeton Review have a combined 65-year track record of helping students achieve academic success, said Joshua H.J. Park, Chief Executive Officer. We’ve brought together the core strengths of both companies to design high-dosage tutoring programs that leverage our comprehensive curricula, proven student engagement strategies, and the effective tutoring methodology that has helped learners succeed for nearly 25 million sessions.

Delivered online in the companies’ updated proprietary virtual classroom within the award-winning LEO™ platform, High-Dosage Tutoring promises to help students make large learning gains and catch up from pandemic-related academic interruptions.

Additional offerings available via the LEO platform include 24/7, on-demand tutoring in 200+ subjects, drop-off writing review services, and The Princeton Review test prep.
