Manners before knowledge.
In Japanese schools, the students don’t take any exams until they reach grade four (the age of 10). They just take small tests. It is believed that the goal for the first 3 years of school is not to judge the child’s knowledge or learning, but to establish good manners and to develop their character. Children are taught to respect other people and to be gentle to animals and nature. They also learn how to be generous, compassionate, and empathetic. Besides this, the kids are taught qualities like grit, self-control, and justice.
