I actually work at a Kumon center right now. I used to teach full-time before DS was born. I primarily work with the younger students (Jr. Kumon) because they require more one-on-one interaction/guidance. Most of these kids are between 3 and 5 years old. I have anywhere between one and four students under my supervision at any given moment. Most of my students do Reading exclusively, although some do both Reading & Math. I have spent a significant amount of time in the main center (older students) as well. Here are a few observations I've made in the time I've been at the center (over a year):
Basically, students do worksheets both at home and at the center. They start at a comfortable (often perceived as "easy") level to begin. The idea of this is to provide the student with a sense of success/accomplishment right from the start (generally speaking, students should not feel frustrated with their Kumon work - a little challenging but not overwhelming). The worksheets are "graded" based on both the number of correct/incorrect answers provided as well as the time it took the student to complete the work. Kumon emphasizes efficiency and accuracy - both are important factors (again, lack of efficiency indicates the student is struggling).
In the particular center I work at, I would say that almost all the students are
not there because they are in need of extra "help". At least 70% of our center's students are enrolled to further challenge what they have learned in school (these kids are not going to Kumon for "tutoring" - their parents just want them to keep ahead of grade-level). From what I have seen, these students do remarkably well with the Kumon method.
On the other hand, the kids who
are struggling when they come to the center (the ones who are in need of a tutoring program) appear to struggle with Kumon just as they would with their schoolwork, reading especially. I've seen Kumon help struggling math students since that discipline is much more cut and dry - there are specific sequences to solving math problems. Plus, math always has a clear right/wrong answer.
All in all, I would only recommend Kumon if you/your child wants to further challenge what they have already learned (they're doing well in school already and would like an extracurricular learning experience) or if you're child is having some trouble with math skills but isn't in need of intense tutoring. Also, both parents and students need to be committed to the program. It will only work if the child does the work regularly. Parents must correct worksheets (as a PP mentioned) and see to it that the child makes corrections to any mistakes. All grades/times for both homework and classwork are entered into the Kumon database and help determine future assignments. If you and/or your child slacks on homework then it will effect progress.
Regarding Jr. Kumon, I wouldn't waste my time or money with that program! Honestly, unless your child is already in kindergarten/first grade and is struggling I wouldn't bother. There are many, many excellent resources available to help teach ABC's and 123's that I personally wouldn't enroll my own DS in Kumon.
