High impact tutoring, also known as high dosage tutoring, is a research-based approach that provides students with consistent, small-group or one-on-one instruction multiple times per week. According to the National Student Support Accelerator, this method significantly boosts academic achievement, especially in math and science. At Calculus Roundtable, we integrate high impact tutoring into our STEM programs by pairing students with trained instructors and STEM majors. These sessions focus on specific learning gaps, reinforce classroom content, and build student confidence. Our structured, data-informed approach ensures each student receives personalized support, helping them make meaningful progress in critical STEM subjects.
