One year-kumon is a long term program, not a short term fix. in many ways its progress is similar to that seen when a child starts learning to play a musical instrument. while students show significant progress inside a year, dramatic results are seen in those students who stay enrolled one to five years or more. to get the most value out of the program, we encourage enrollment for a minimum of a year. we collect a last months deposit which is not refundable unless the student has remained enrolled a minimum of one year.
