There has been a growing body of research that proves that Montessori students perform as well or better than non-Montessori school children. A method of schooling that focuses on personal development rather than exams produces more mature, creative and socially skilled children, scientists have found. In one of the researches conducted, it was proved that five-year-old Montessori pupils were better prepared for reading and math, and 12-year-olds wrote "significantly more creative" essays using more sophisticated sentence structures. Montessori children display greater values like ‘Empathy and Honestly’, ‘Respect and Responsibility’ as compared to non-Montessori children.
