Reggio Emilia vs Montessori vs Waldorf: What the Labels Mean, and Why They Can’t Tell You What You Need to Know

All four of my kids went to Montessori preschool, and I’d still tell you not to pick a school because of the word on the sign.

We’re a Montessori family, more or less. There’s a floor bed instead of a crib in our history, real knives in small hands, a kitchen the kids are allowed in, and I’ve written about why here. I also love a lot of what Waldorf believes about open-ended play and art, and I’ve borrowed from it. So this isn’t going to be a neutral comparison written by someone who googled all three yesterday, and it also isn’t going to end with “and the winner is,” because after eleven years inside the school system and a decade of raising kids outside it, I’ve come to think the label on a program is one of the least reliable things about it. What follows is what the three words mean, what each one was built to fix, what the research says, and then what to do with that.

What each approach is (the short, fair version)

Montessori is the oldest and the most specific. Maria Montessori opened the first Casa dei Bambini in Rome in 1907, and what she built is a method: a prepared environment of carefully designed materials on low shelves, children choosing their own work and working on it uninterrupted for long stretches, mixed-age classrooms in three-year bands, and a teacher who observes and guides rather than lectures. Practical life (pouring, sweeping, buttoning, cutting) is treated as real work. Reading and math start early, through the materials, when the child is ready, which is often younger than a conventional school would start.

Waldorf comes from Rudolf Steiner, who opened the first school in Stuttgart in 1919 for the children of a cigarette factory’s workers. Where Montessori is a method, Waldorf is closer to a worldview. Early childhood is for play, imitation, rhythm, stories, art and handwork, and formal reading instruction doesn’t begin until around seven. The days and seasons have a rhythm. Screens are kept out of the early years on principle. Imagination is treated as the main work of a young child, and the materials are natural: wood, wool, silk, beeswax. Underneath all of it is Steiner’s anthroposophy, a spiritual philosophy that shapes the curriculum more than most parents realize when they enroll.

Reggio Emilia isn’t a method at all; it’s an approach that grew out of one town. After the Second World War, parents in the villages around Reggio Emilia, Italy, built schools with the educator Loris Malaguzzi, and what developed is a set of principles: children have “a hundred languages” (painting, building, drama, movement) and should be allowed to express their thinking in all of them; the environment is “the third teacher” and is designed with light, plants and studio space; teachers document children’s work obsessively and shape the curriculum from what the children are already curious about; learning happens in long, open-ended projects that a small group drives. It’s early-years only, and because it isn’t a method, anyone can call anything “Reggio-inspired,” which is where my trouble with labels begins.

What the research says

Montessori is the only one of the three with a serious evidence base, and it’s good. In 2017 Angeline Lillard’s team published a three-year study of 141 children who had entered public Montessori preschools by lottery, so the comparison was fair: Montessori kids ended up ahead in reading, vocabulary and math, ahead in understanding other people’s minds, more likely to choose a hard task over an easy one, and the gap between low-income and high-income children nearly closed, from an effect size of 0.61 to 0.21. That’s a lottery study, which is the gold standard, and it tells you the method works when it’s done properly.

The catch, which Lillard herself has written about, is that “Montessori” isn’t a protected term. Any school can use it. The high-fidelity classrooms in that study look very different from a lot of what’s sold under the name, and that difference, not the name, is what the research is about.

Waldorf has far less research behind it, and some of what exists is about problems: the late start on reading can leave kids behind if the family doesn’t support it; the movement has struggled with pseudoscientific content, with Steiner’s own racial theories in the founding texts, and with vaccine hesitancy in its communities. I say that as someone who loves the play philosophy. You can take the open-ended play, the rhythm, the art, the no-screens stance, and leave the rest, and a lot of good Waldorf teachers do exactly that, but you should know the rest is there.

Reggio has almost no outcome research, for the reasonable reason that it’s a set of principles practiced differently in every room. What it has is a hundred years’ worth of agreement among people who study early childhood that its principles are right.

Why the label can’t tell you what you need to know

The labels are misused constantly, and you cannot count on any of them to tell you the quality of the program. I have seen “Montessori” schools that were a conventional preschool with wooden toys and a brochure. I have seen “Reggio-inspired” that meant there were plants. I have seen Waldorf programs that were beautiful and others that were rigid about everything except the thing that mattered. And I taught for eleven years in a system with no label at all that was doing far more damage than any of them, which is the real comparison: all three of these were built by people who looked at conventional schooling and said no, and all three are better than the default when they’re done well.

Done well is the whole question, and it lives in the room, not the name.

What to look at instead

Go stand in the room for an hour. Not the tour: the room, while the children are in it.

Watch what the children are doing and for how long. In a good room of any label, most of the kids are absorbed in something they chose, and they stay with it. If they’re being moved from station to station on a bell, the label doesn’t matter.

Watch the adult. Is she talking all the time, or watching? Does she rush in when a child struggles, or wait? A teacher who can leave a three-year-old alone with a hard thing is worth more than any certificate on the wall.

Look at what’s in reach. Real materials, at child height, in good condition, a reasonable number of them. A room stuffed with plastic is not Montessori or Reggio or Waldorf whatever the sign says, and I’ve written about why the number of things matters here.

Ask how they handle conflict, and listen for whether the children are expected to work it out or the adults always settle it. Ask how much of the day is outside. Ask whether there are screens, and if the answer is anything other than “no,” ask why.

And then ask yourself the question that cuts through all three philosophies: does this room treat my child as someone who can already do things, or as someone who has to be managed until she’s older? Montessori, Waldorf and Reggio all answer that the first way. So should the school. If it doesn’t, the word on the sign is decoration.

One thing

Before you choose, spend one hour in the actual classroom while it’s running, and count how many children are absorbed in something they chose. That number will tell you more than the name.

I write every week about what childhood is for and how to protect it from the things built to fill it. You can find me on Instagram or join the list.
