This allows the teacher to develop a deeper understanding of a child's strengths and needs, and is therefore in a better position to support the child's learning. Children have several years to develop, and are able to see themselves as progressive, successful learners. Children are viewed as unique individuals. The teacher focuses on teaching each child according to his or her own strengths, unlike in same-grade classrooms that often expect all children to be at the same place at the same time with regard to ability. Children are not labeled according to their ability.
Children learn at their own rate, with no fear of retention.
In same-grade classrooms, children are retained if they do not master content by the end of the year. In mixed-age classrooms, children have more time to master content, and this removes their fear of being retained in school. Children develop a sense of family with their classmates. Older children have the opportunity to serve as mentors and to take leadership roles. Children are more likely to cooperate than compete.
