Although there have been many studies of Montessori education, most have involved only 1-2 schools; while results are largely positive, those schools might just be especially good ones. A new study of 24 schools across the US enrolled 588 children and used an intention-to-treat randomized design to see if the outcomes of children who were randomly admitted to public Montessori schools at age 3 by a lottery (because the schools were oversubscribed) differed in end-of-kindergartent (ages 5-6) outcomes from those who were not admitted. The results of this study will be presented.
