Bullying in schools is not random. Research consistently shows that it is structured around status hierarchies, social comparison, and the need for peer validation. Understanding this matters because it points to why certain school environments produce more bullying than others, and why Montessori classrooms, in particular, are structurally different in ways that reduce the conditions that allow bullying to take root.
This article explains the specific mechanisms: what Montessori does and does not do, what the research evidence shows, and where the honest limits of that evidence lie.

Why Bullying Happens: The Social Structure That Enables It
Bullying is not caused by “bad” individual children. Research on its origins consistently points to social structures and environmental conditions that make it more or less likely. According to a review published in PMC (2024), most children who bully others hold considerable social power within their peer network and are often perceived by peers as popular, socially skilled, and leaders. They use aggression instrumentally to establish and maintain their social position.
This means bullying is fundamentally a status phenomenon. It thrives in environments where status hierarchies are clear, where social comparison is constant, where peer groups are fixed and closed, and where children have few legitimate ways to establish their position other than through dominance. Most conventional school environments create exactly these conditions, often unintentionally:
Grades and academic ranking
Visible ranking systems create clear winners and losers. Children at the bottom of visible hierarchies are more vulnerable; those at the top have social capital to protect or leverage.
Single-age cohorts
Children spending all day with the same 25-30 peers of identical age creates intense social comparison and closed social groups where peer pressure concentrates.
Competition for limited teacher attention
When the teacher is the primary source of approval and feedback, children compete for that approval, creating performance-based social dynamics.
Reward and recognition systems
Star charts, student-of-the-week, public praise for achievement all make the status hierarchy visible and create clear targets for both emulation and resentment.
Montessori classrooms remove or significantly alter all four of these structural features. This is not accidental. It reflects Montessori’s philosophy that children should work for intrinsic satisfaction rather than social approval, and that a community of learners functions better when cooperation replaces competition. The question is whether these structural differences translate into measurable differences in social outcomes.
The Four Structural Features That Change the Social Dynamic
1. No grades, no visible academic ranking
Montessori classrooms have no grades, no test scores, no star charts, and no competitive recognition systems. The absence is structural, not accidental. In Montessori, the material itself provides the feedback: a cylinder block that does not fit correctly tells the child something is wrong without involving the teacher or any other child. Progress is tracked by the teacher through individual observation records, but it is not displayed, ranked, or compared. Children working in the same room on different materials at different stages of the same sequence have no visible way to compare their academic position.
The research on motivation explains why this matters: Lillard et al. (2017) found that Montessori preschool children showed stronger mastery orientation than controls, meaning they chose harder tasks and persisted longer. This is consistent with decades of research showing that extrinsic reward systems shift children toward performance goals (looking competent, avoiding failure) and away from mastery goals (genuine learning, accepting challenge). Performance goals create social comparison; mastery goals reduce it. When there is nothing to publicly win or lose, the status stakes of academic achievement drop considerably.
2. Multi-age grouping disrupts peer cohort dynamics
In a conventional school, a child spends an entire year with the same 25-30 peers of identical age. This creates a closed social system with high comparison pressure and fixed social positions. Cliques form early and are hard to leave. The child who is perceived as “at the bottom” of the social hierarchy in September is usually still there in June.
Montessori classrooms group children in three-year spans: 3-6, 6-9, 9-12. In any given classroom, a six-year-old is simultaneously the eldest in relation to the four-year-olds and the youngest in relation to the five-year-olds who are preparing to move up. Social identities are more fluid and more varied. An older child who might occupy a low-status position in a same-age peer group often finds a legitimate high-status role as a mentor and demonstrator to younger children. The PMC 2024 bullying review notes that high conscientiousness and agreeableness act as protective factors against peer pressure; the mentoring role that multi-age classrooms create may develop exactly these qualities.
3. Self-directed work reduces competition for adult approval
When the primary source of feedback in a classroom is the teacher, children compete for that feedback. They seek approval, they notice who gets praised and who does not, and they develop social strategies for maintaining their position in the teacher’s estimation. This competitive dynamic for teacher attention is one of the conditions that makes classroom social hierarchies rigid.
In Montessori, the teacher is not the primary source of feedback. The material is. Children are not working to impress the teacher; they are working because the material is genuinely engaging and because mastery is its own reward. During the work period, the teacher is largely peripheral. This dramatically reduces the social significance of teacher approval and the status that comes with it. Children who are not competing for the same resource are less likely to undermine each other in the process of acquiring it.
4. Grace and courtesy: social skills taught explicitly and early
Montessori classrooms include a specific category of practical life work called “grace and courtesy” lessons: structured presentations on how to greet someone, how to interrupt politely, how to ask for help, how to resolve a disagreement, how to move through the room without disturbing others’ work. These are taught as seriously as any academic lesson and practiced repeatedly.
This is not the same as posting rules on a wall. It is the direct, explicit teaching of conflict resolution and social interaction skills to children who are still developing them. The PMC review on emotional intelligence and bullying (2024) notes that children with low emotional intelligence are more likely to become perpetrators due to poor conflict resolution and poor emotional control. Grace and courtesy lessons address exactly this developmental gap, at the age when the habits are being formed.
What the Research Shows
The evidence on Montessori and social outcomes is encouraging, though more limited than the evidence on academic outcomes. Here is what the studies show, described accurately.
Social competence and problem-solving
The longitudinal RCT by Lillard et al. (2017) tested children’s social problem-solving using the Rubin Social Problem-Solving Task. Children in high-fidelity Montessori preschools generated more sophisticated solutions to peer conflict scenarios than control children. Montessori children were more likely to propose negotiated, turn-taking solutions rather than simply appealing to a teacher or using force. This finding was consistent with prior studies by Lillard and Else-Quest (2006), who found that Montessori students showed better playground interactions and more positive peer behaviours. The 2023 systematic review confirmed that social skills showed an effect size of g = 0.22 in favour of Montessori across the 32 included studies.
Executive function and emotional regulation
Multiple studies, including the high-fidelity Montessori preschool studies by Lillard (2012) and Lillard et al. (2017), found stronger executive function in Montessori children compared to controls. Executive function includes self-regulation, inhibitory control, and cognitive flexibility. These capacities are directly relevant to bullying prevention: children with strong self-regulation are better able to pause before acting aggressively, consider consequences, and choose a different response. Research on bullying perpetration consistently identifies poor self-regulation as a risk factor; developing it early is protective.
Equity across race and socioeconomic background
A 2023 study by Lillard, Tong, and Bray examined 134 non-white and white preschoolers. Non-white children in Montessori settings scored significantly higher on executive function, social cognition, and early academics than their non-white peers in conventional programmes. This matters for bullying specifically because research consistently shows that children from marginalised racial and socioeconomic backgrounds face higher rates of peer victimisation. An educational environment that actively narrows these gaps rather than amplifying them has direct implications for the social dynamics of the classroom.
The Honest Limits of the Evidence
Montessori classrooms are not immune to bullying. No educational environment is. Being precise about what the evidence supports and what it does not is essential for parents making decisions about their child’s schooling.
What the evidence supports:
- Montessori children show stronger social problem-solving skills than comparable peers in conventional programmes
- Montessori children show stronger executive function and self-regulation, which are protective factors against both perpetrating and experiencing bullying
- High-fidelity Montessori environments structurally remove several of the conditions that research associates with higher bullying rates: grades, visible ranking, competitive reward systems, and rigid single-age cohorts
What the evidence does not support:
- That bullying never occurs in Montessori classrooms. It does.
- That attending a Montessori school “prevents” a child from being bullied. There is no such guarantee.
- That the Montessori effects are entirely caused by the method itself. Families who choose Montessori tend to be more educated and more invested in their children’s social and emotional development: these family characteristics independently predict better social outcomes
- That Montessori schools are universally high-fidelity. A poorly implemented Montessori classroom may not produce these structural differences
The research on Montessori and social outcomes is real and meaningful. The structural arguments about why Montessori should reduce bullying conditions are also well-grounded. But they should be understood as probability-shifting rather than guaranteed. A Montessori environment makes certain conditions for bullying less likely. It does not make bullying impossible, and a child who is experiencing bullying in a Montessori setting should be taken just as seriously as one experiencing it anywhere else.
If Your Child Experiences Bullying in a Montessori Setting
Montessori educators are trained to observe children closely and to address conflict through specific processes, including community meetings where children raise concerns, discuss them, and collaboratively find solutions. These processes are built into the school day in high-fidelity settings. If your child is experiencing bullying:
- Speak with the teacher directly and specifically. Describe what your child has observed or experienced in concrete terms, not general concerns about the classroom. A trained Montessori teacher will have observation records and will be able to respond specifically.
- Ask how the classroom community meetings address this. If the school does not have a community meeting practice, this is a gap in their implementation of the Montessori philosophy.
- Practise conflict resolution language at home. Role-play scenarios with your child. Rehearsing specific phrases for setting limits (“I don’t like that, please stop”) and for seeking help builds practical confidence.
- Watch for signs of anxiety, withdrawal, or reluctance to attend school. These are the most reliable indicators that a child’s experience of the social environment is affecting their wellbeing, and they warrant prompt attention regardless of the school type.
Questions Parents Ask Most Often
Is bullying less common in Montessori schools than in conventional schools?+
The evidence suggests yes, though the research is limited and not definitive. High-fidelity Montessori classrooms structurally remove several conditions that research associates with higher bullying rates: competitive grading, public ranking, reward systems based on comparison, and rigid same-age peer cohorts. Studies consistently show stronger social problem-solving and prosocial behaviour in Montessori children. However, we cannot make categorical claims. Selection effects (families who choose Montessori may already have stronger social support at home), variation in implementation quality, and limited direct studies of bullying in Montessori settings all mean the honest answer is “probably less, under the right conditions, but not zero.”
My child is confident and strong-willed. Will they be bored without competition in Montessori?+
Montessori does not remove challenge; it redirects it. A strong-willed, capable child in a Montessori environment is challenged by the intrinsic difficulty of the materials, by the mentorship role they take on as an older child in a multi-age group, and by the internal standard of mastery rather than by external ranking. Research suggests this produces stronger mastery orientation than competitive environments: children who choose harder tasks because they genuinely want to master them, rather than because winning against peers provides the motivation. Many children who are deeply competitive in conventional environments find Montessori more engaging rather than less, because the competition is with themselves rather than with others who can be avoided or dominated.
How does Montessori address cyberbullying?+
Cyberbullying happens outside the school environment and involves digital platforms that are separate from what any school can control. Montessori education does not address this directly. What it does address is the social-emotional foundation: children with stronger empathy, better emotional regulation, and more secure social identities are better equipped to navigate digital social environments and more resistant to the peer validation dynamics that cyberbullying exploits. The structural protections of the Montessori classroom (no public ranking, no social comparison through grades) do not follow a child onto Instagram or WhatsApp. These require direct family engagement, open communication, and age-appropriate digital guidance, which are the responsibility of parents regardless of the school type.
Structural Change Over Symbolic Change
What makes Montessori’s approach to bullying and peer pressure distinctive is not that it talks about kindness or posts respect posters on the walls. It is that the structure of the environment removes several of the conditions that make bullying socially rewarding. No grades to compete over. No single-age cohort to dominate. No teacher approval to hoard. No reward system to game. When the social incentives that typically drive status-seeking aggression are absent, children find other ways to establish their place in the group. The research shows they generally find better ones. That is the Montessori argument, and the evidence, while limited, supports it.
