Repetition provides students with the necessary review to increase their level of mastery and advance to higher-level materials. By assigning appropriate repetition, it is possible for students to continue progressing smoothly while remaining motivated and interested in their studies. Many factors are considered when Instructors individualize their lesson planning. Repetition spans and the number of repetitions students need will vary according to their ability, approach to studying, and their learning attitude.

A student’s recorded completion time is a key measure to evaluate whether a student should keep advancing or continue practicing content in a skill through repetition. Based upon statistics derived from students, the Standard Completion Time (SCT) has been determined for each set of worksheets from Math Level 4A and Reading Level 2A. The list of SCT is published in the Kumon Table of Learning Materials. Instructors use the SCT as a guideline and compare it with a student’s completion time.

Instructors observe and evaluate a student’s learning situation and accuracy when making instructional decisions. Conscientious students who approach their worksheets independently and enthusiastically are considered to have a great learning attitude. Instructors also observe a student’s ability to concentrate on the assigned worksheets and aim for students to complete the worksheets comfortably without getting distracted or slowing down dramatically. When students ask questions while studying they may be indicating that their level of understanding needs more practice. Accordingly, the Instructor may adjust the rate of a student’s progress by assigning repetition and this enables students to continue studying smoothly, without losing interest or motivation.
