Introduction
Walk into three different preschools and you might see three entirely different classroom philosophies in action — one with children silently absorbed in individual tasks, one filled with collaborative art projects documented on the walls, one structured around a specific daily “plan-do-review” sequence. These reflect three of the most influential early childhood education models: Montessori, Reggio Emilia, and HighScope. This article compares their origins, core philosophies, classroom structures, and the research behind each, to help you understand — or choose between — them.
Montessori Method
Origins and Philosophy
Developed by Italian physician and educator Maria Montessori in the early 1900s, the Montessori method is built on the belief that children learn best through self-directed activity within a carefully prepared environment, guided but not directed by trained adults (“the teacher follows the child”).
Classroom Structure
- Mixed-age classrooms (typically spanning 3-year age ranges, such as 3–6 years), allowing younger children to learn from older peers and older children to reinforce learning by teaching
- Specially designed materials, such as the Montessori “pink tower” or sandpaper letters, each designed to isolate a specific skill and allow for self-correction without adult intervention
- Long, uninterrupted work periods (often up to three hours), allowing children to engage deeply with self-chosen activities
- Minimal adult-directed group instruction; teachers (“directresses”) primarily observe and offer individual or small-group lessons
Teacher’s Role
The Montessori teacher acts as a guide and environment designer, demonstrating how to use specific materials and then stepping back to allow independent exploration, intervening minimally unless invited or needed for safety.
Reggio Emilia Approach
Origins and Philosophy
Originating in the town of Reggio Emilia, Italy, after World War II, this approach — associated with educator Loris Malaguzzi — is built on the idea that children are capable, curious co-constructors of their own learning, expressing understanding through “the hundred languages of children” (art, movement, words, and more).
Classroom Structure
- Emergent curriculum: Projects and learning topics emerge from children’s own interests and questions, rather than a fixed predetermined curriculum
- Documentation: Teachers extensively document children’s thinking and work (photos, transcribed quotes, displayed projects) both as a learning tool and to make children’s thought processes visible to families and other children
- The environment as “the third teacher”: Classrooms are intentionally designed as aesthetically rich, thoughtfully organized spaces that invite exploration, often including natural materials, mirrors, and open-ended art supplies
- Long-term, in-depth projects, sometimes lasting weeks or months, allowing children to explore a topic (such as “shadows” or “the rain”) from multiple angles
Teacher’s Role
Reggio Emilia teachers act as co-researchers and collaborators alongside children, asking probing questions and extending projects based on children’s expressed interests, rather than directing a fixed lesson plan.
HighScope Approach
Origins and Philosophy
Developed in the United States, closely associated with the Perry Preschool Study (one of the most cited longitudinal studies in early education research), HighScope is built on Piagetian constructivist principles, emphasizing “active participatory learning” within a structured daily routine.
Classroom Structure
- “Plan-Do-Review” sequence: Children plan an activity, carry it out, then reflect on and discuss what happened — a structured cycle designed to build intentionality and self-reflection
- Key Developmental Indicators (KDIs): A defined set of skills across domains (language, math, social-emotional, etc.) that guide curriculum planning, though within a flexible, child-initiated framework
- Consistent daily routine, providing predictability while still allowing significant child choice within that structure
- Small-group and large-group times, alongside individual work time, balancing structure with autonomy
Teacher’s Role
HighScope teachers actively engage with children during their chosen activities, using specific strategies (like “scaffolding” through open-ended questions) to extend learning within the child’s own chosen activity, while also facilitating the plan-do-review process.
Side-by-Side Comparison
| Feature | Montessori | Reggio Emilia | HighScope |
|---|---|---|---|
| Origin | Italy, early 1900s (Maria Montessori) | Italy, post-WWII (Loris Malaguzzi) | United States, 1960s |
| Curriculum source | Prescribed sequence of specialized materials | Emergent, driven by children’s interests | Structured framework (KDIs) with child choice |
| Classroom age grouping | Mixed-age (3-year spans) | Often mixed, varies by school | Typically single-age |
| Core daily structure | Long uninterrupted individual work periods | Long-term project work, flexible daily rhythm | Consistent plan-do-review cycle |
| Teacher role | Guide/observer, minimal intervention | Co-researcher, collaborator | Active scaffolder within child’s activity |
| Assessment approach | Observation of material mastery | Documentation of the learning process | Structured observation against KDIs |
What Research Says
- Montessori: Several studies, including research published by Angeline Lillard, have found Montessori students show comparable or stronger outcomes in academic and social-emotional measures compared to conventional preschool students, particularly in “classic,” well-implemented Montessori programs.
- Reggio Emilia: Because Reggio programs vary significantly in implementation and the approach resists standardized curricula (making controlled research harder), there is less large-scale quantitative research compared to Montessori or HighScope, though qualitative research consistently highlights strong outcomes in creativity, collaborative skills, and expressive language.
- HighScope: The Perry Preschool Study, one of the most rigorously studied early education interventions in existence, used a HighScope-based curriculum and found significant long-term benefits in educational attainment, earnings, and reduced criminal justice involvement decades later.
Choosing Between Them: What to Consider
- If you value structured independence and skill-specific materials, Montessori’s self-correcting materials and long work periods may be a strong fit.
- If you value creative expression, collaborative projects, and flexible, emergent curriculum, Reggio Emilia’s project-based approach may align well.
- If you value a balance of structure and choice, with a strong evidence base tied to long-term outcomes, HighScope’s plan-do-review framework offers a well-researched middle ground.
In practice, many programs blend elements from multiple models rather than adhering strictly to one — it’s worth asking any specific program how (and how consistently) they implement their stated philosophy, since fidelity to a model varies widely between individual schools claiming the same label.
Frequently Asked Questions
Q: Is one of these models proven to be “the best”? A: No single model has been definitively proven superior across all outcomes — each has research support, and the right fit often depends on a child’s temperament, family values, and how faithfully a specific school implements the model.
Q: Can these approaches be combined? A: Yes, many schools blend elements — for example, using Montessori materials within a more flexible, Reggio-inspired emergent curriculum structure — though purists in each tradition may consider this a departure from the “authentic” model.
Q: Are Montessori schools all essentially the same? A: No — “Montessori” is not a trademarked or universally regulated term in most countries, so implementation quality and fidelity to Maria Montessori’s original method vary significantly between schools using the name.
Q: Which model has the strongest research base for long-term outcomes? A: HighScope has the most extensive long-term longitudinal research behind it, primarily due to the Perry Preschool Study, though Montessori also has a substantial and growing body of comparative research.
Q: Is Reggio Emilia harder to implement well compared to the other two? A: Because Reggio Emilia relies heavily on emergent curriculum and skilled teacher improvisation rather than a fixed set of materials or sequence, some educators consider it more dependent on teacher skill and training to implement consistently well.
