Montessori programs in public schools produce better academic outcomes than conventional public school programs.

Is it true that Montessori programs in public schools produce better academic outcomes than conventional public school programs?

Unclear. A 2023 systematic review reports small positive academic effect sizes favoring Montessori overall, but its moderator analyses found smaller effects for public Montessori than private, and a French preschool RCT found mostly comparable outcomes with a reading advantage only. A South Carolina study compares public Montessori achievement to traditional schools but the retrieved excerpt does not state its results.
