Some people may think that the larger the class the better, or that the school must be good if it has lots of students. This is not necessarily the case. If the class is large then the instructor can’t spend as much time with each student. Some of my Senior students like it when they are on there own or just two of them as it’s like having private tuition.
The advantage of a small class is therefore obvious whereby the student get more time from the instructor correcting their techniques or explaining to them more thoroughly than they could with a larger class. Furthermore, the small classes tend to be more relaxed and focused making the lesson more enjoyable.
The smaller class is typical of the Okinawan Karate system and this is what I saw and trained while I stayed at Sensei Takashi Kinjo’s dojo in Naha, Okinawa. The Japanese on the other hand can be large, especially in the University groups, therefore they become more military style and very regimented. This can be very stressful for a beginner.
So class sizes tend to be 10-15 for Little Dragons and 10-20 for Seniors/Juniors. However, there are places available as students come and go. For example moving out the area, or going to University, and even finding relationships.
