What is the minimum Age accepted?

In order for a child to have a sufficient attention span and skill level, the age of 10 would be appropriate. We have had several students attend under this age who completed both days with distinction, but they were quite experienced riders. We like to focus on providing "great value for money" for each student so this might not be attainable for a very young rider who is at the beginner stages of learning. The first day would be very applicable to them, however the second day, when we start to apply our skills in more advanced situations, may be a little too much for them (or their equipment).
Previously, for the lesser skilled youth riders we have just had them attend the first day of the school. The cost for this is $200. Sometimes we will wait until the end of the first day to re-evaluate whether the student is of a high enough skill to complete the second day of the school at a satisfactory level. Again, one of the main aims of our school is to ensure that all students receive "value for money" for their investment; you as the parent are the best gauge in evaluating your child's physical, emotional and cognitive development to make sure we are able to meet this aim.
