Montessori
A prepared room, mixed ages, long uninterrupted work, and the child chooses within it.
Children choose their own work from carefully designed materials, in mixed-age classes, across a long uninterrupted morning. The structure is in the environment rather than in the timetable: what is available is tightly controlled, and what a child does with it is not. Adults observe far more than they instruct.
Not what it promises
Every approach here works for the families it suits; the useful question is what it costs to run.
- Accepting a school where nobody will tell you what your child did at 10am
- Trusting a long ramp — the method front-loads independence and back-loads visible output
- Checking the school rather than the name, which anyone may use
- Usually fees, since state Montessori is rare outside a few systems
How it gets misread
Taken for a free-choice environment. The choice is real and the range it is exercised over is unusually narrow — that is the design.
Where it stands
Every position with the source it was read from, and the pale band is how much internal variation the approach genuinely tolerates. A wide band is not vagueness — it means the texts in this family really do disagree with each other about that axis.

Mixed age is structural rather than incidental — the three-year span is how the teaching happens.

The Absorbent Mind
Maria Montessori, 1949. Primary text for the prepared environment, mixed-age groups, the three-hour work cycle and the adult as observer.
Montessori: The Science Behind the Genius
Angeline Lillard, Oxford University Press, 3rd ed. 2016. What the outcome evidence supports, by a sympathetic researcher who is careful about the difference between the method and schools using the name — which is unprotected.
