Kumon is supplementary education built on a proprietary self-learning method, where the child works through finely graded worksheets at their own pace. It rests on two core subjects — math and reading — and the student attends a local centre once or twice a week and completes daily assignments at home. What sets it apart is exactly this method: the instructor doesn't lecture but assesses the child, sets the right level, and guides them toward becoming an independent, confident learner.
