What It Means
A Montessori school is a school, public or private, that teaches by the method Maria Montessori developed. The American Montessori Society (AMS) names five core components it treats as essential: teachers trained in Montessori, classrooms that mix ages, Montessori learning materials, work the child chooses, and long periods of uninterrupted work. Schools differ in how fully they follow these, so a visit tells you more than the name.

The Breakdown
What to look for, per AMS's five core components
| Component | What it looks like |
|---|---|
| Trained teachers | Certified by an accredited Montessori teacher education program for the age level they teach |
| Multiage classrooms | Several ages share a room; younger children learn by watching older ones, and older ones reinforce what they know by teaching |
| Montessori materials | Montessori learning materials suited to the children's stage of development |
| Child-directed work | Children choose their work and move at their own pace |
| Uninterrupted work periods | Long blocks without interruption; AMS aims for close to three hours a day and no less than two |

Public or private. AMS says more than 500 public schools in the U.S. offer Montessori programs. In a public one, teachers also hold a state license for the level they teach, and students take the same state standardized testsStandardized testingTests given and scored the same way for every student; in U.S. public schools, mainly the yearly state tests in reading, math and science that ESSA requires.
