- Curriculum-driven materials: High-quality curricula reinforce in-school learning.
- Consistent, relational learning: Longstanding tutor–student relationships accelerate learning and promote individualized instruction.

Since the pandemic, students have experienced math learning loss not seen in two decades. According to the NAEP Report Card, the average eighth-grade mathematics score was “lower than all previous assessment years going back to 2003.”
Within math, Algebra looms large as a gateway subject that prepares students to tackle advanced study in calculus, physics, and other areas. Algebra presents significant challenges as well as major opportunities for students to attain academic and professional success. Without a solid understanding of Algebra, students often find that they get stuck in their math studies.
In 2022, utilization of Tutor.com’s on-demand Algebra tutoring reached an all-time high of nearly 100,000 K–12 sessions, more than double the number from the previous year. Not only were students pursuing help at higher rates than ever before, but they were also engaging in longer and more frequent sessions than in previous years. In 2022, the number of long Algebra sessions (defined as being 75% longer than average) more than doubled.
As part of a Multi-Tiered System of Support with on-demand tutoring, High-Dosage Tutoring provides a way for K–12 schools and districts to help students close knowledge gaps and make significant, accelerated learning gains.
This fall, middle and high schools can adopt High-Dosage Tutoring to provide for their Algebra students during the school day.
(Additional subjects and grade levels will be available in the coming months.)

Here’s what users are saying:
“Huntington Beach Union High School District values the partnership we have with Tutor.com for many reasons. First, they offer bilingual English, Spanish, Vietnamese, Mandarin, and French tutors which helps level the playing field for our English learners. Tutor.com also runs analytics that provide insights into how students are using the tool, in which subject areas students are struggling, and during what times of the day or night our students are logging in.
The customer service Tutor.com provides is outstanding, and they are always willing to visit our school campuses, talk to our teachers/administrators/families, and present at Professional Development workshops. Additionally, having 24/7 free tutoring services for all our students promotes equity and accessibility because, for many of our parents, paying for a tutor is not fiscally possible."
