Teacher looping refers to the practice of keeping the same teacher with the same group of students for at least two years in a row. Studies now confirm that teacher looping is strongly correlated with better educational outcomes, surpassing those associated with extra time during homework. Waldorf schools have been using teacher looping for decades based on the knowledge that longevity of relationship is a hallmark of effective learning.

A study published in American Journal of Public Health (AJPH) found that children’s prosocial skills predict key successful outcomes for adolescents and adults including education levels, employment stability, and increased mental well being.
