It has been proven over and over that lower student to teacher ratio is optimal for learning. A private 30 minute lesson is 30 minutes with an instructor. A group lesson for a half hour with four students is 7 minutes per student with the instructor. Private lessons are guaranteed to get your child safer in the water. At Sunsational Swim we specialize in quick and effective learning through one-on-one lessons that are individually tailored to the student's learning style and developmental level to guarantee progress at all ages.
