Multiage education is the intentional grouping of children of different ages, abilities, and emotional maturity in the same classroom. Students in our program are continually regrouped for different learning activities rather than being consistently segregated by chronological age. Within these structures, children progress along a continuum of simple through more complex material at their own rates, making continuous progress rather than being "promoted" to the next grade at the end of a school year. In multiage programs, students typically stay with their teacher for 2 to 3 years. With the beginning of each new school year, one-half to two-thirds of the students from the previous year's class remain together, with only the oldest students entering new classes.
