Bullying is generally understood as behaviour that deliberately causes harm, distress, humiliation or social exclusion and is characterised by repetition or an ongoing pattern, together with a power imbalance or difficulty for the targeted person in stopping the behaviour. It can be physical, verbal, relational, social, psychological or digital, and it may involve one person or a group acting against another person.
Common examples include repeated insults, threats, physical intimidation, deliberate exclusion, spreading harmful rumours, damaging belongings, coercive behaviour and persistent online harassment. Definitions vary between jurisdictions and organisations, so particular legal or institutional definitions may emphasise different elements. A single serious incident may not meet a formal definition of bullying while still constituting harassment, violence, abuse or other unacceptable conduct requiring action. Conversely, bullying does not have to involve physical aggression. Social manipulation, humiliation and exclusion can have significant effects even when there is no physical contact. Understanding the precise definition used by a school is therefore important when interpreting individual cases.
One of the most important characteristics of bullying is the relationship between power and vulnerability. Power can be physical, social, numerical, psychological, economic, technological or institutional. A pupil may be targeted because another pupil has greater physical strength, a larger friendship group, higher social status, access to embarrassing information or greater technical knowledge. Power can also change over time, meaning that a pupil who appears socially confident in one environment may be vulnerable in another.
Repetition can involve repeated acts rather than identical incidents. For example, recurring exclusion, repeated messages, continuing intimidation or a persistent pattern of humiliating comments may constitute an ongoing course of behaviour. Some definitions also recognise that an isolated incident can become part of a bullying pattern when it occurs alongside previous behaviour. The concepts of intention and impact can likewise be complicated. A person may claim to have been joking, but repeated behaviour that causes distress and exploits an imbalance of power still requires appropriate investigation and response.
Bullying can take several forms. Physical bullying includes hitting, pushing, kicking, unwanted physical contact or damaging possessions. Verbal bullying includes repeated insults, threats, mocking, humiliating comments and abusive language. Relational or social bullying involves exclusion, manipulation of friendships, spreading rumours, deliberate isolation or attempts to damage a person's social standing. Psychological bullying can involve intimidation, coercion, humiliation and sustained fear.
Prejudicial bullying targets characteristics such as disability, race, religion, sex, sexual orientation or other protected or personal characteristics, depending on the legal framework. Cyberbullying involves digital communication or technology and can overlap with all of these categories. Sexual harassment can also overlap with bullying but has its own legal and safeguarding dimensions. These categories are useful for understanding patterns, but real incidents can involve several forms simultaneously. For example, a pupil might be excluded socially, mocked verbally and targeted through group messaging at the same time.
Bullying differs from ordinary conflict, disagreement and isolated unkindness, although the boundaries can require careful assessment. Conflict generally involves opposing interests or disagreements between people who have relatively comparable power, whereas bullying typically involves a persistent harmful pattern and an imbalance that makes resistance difficult. An argument between two pupils does not automatically constitute bullying simply because one person is upset afterwards. Likewise, one insulting comment may be unacceptable without meeting a formal bullying definition.
However, these distinctions should not become reasons for inaction. Schools may need to intervene in harmful behaviour regardless of whether the formal label bullying applies. The investigation should consider what happened, how often it occurred, the relationship between the people involved, the effect on the targeted pupil, evidence from witnesses or digital records, and whether there is an ongoing risk. A narrow focus on terminology can obscure the practical requirement to protect pupils and address harmful conduct.
Bullying can occur in many environments, including classrooms, playgrounds, transport, sports activities, residential trips and digital spaces. It can also move between environments. For example, a conflict that begins at school may continue through private messaging or social media after school hours, while online hostility can affect relationships and safety when pupils return to school. Digital communication can make bullying particularly persistent because harmful material can be copied, forwarded, stored or viewed repeatedly.
An audience may also increase the social impact, while anonymous accounts can make identification difficult. Nevertheless, cyberbullying shares fundamental characteristics with other forms of bullying, including harm, repetition or persistence, social dynamics and power. Schools therefore commonly need to consider both the immediate incident and the wider relationship between pupils. Evidence can include messages, screenshots, photographs, videos, platform records, witness accounts and direct disclosures, although evidence should be handled carefully and confidentially.
The effects of bullying can involve education, relationships, participation, emotional wellbeing, physical safety and attendance. A pupil experiencing persistent bullying may avoid particular areas of school, withdraw from activities, become reluctant to participate in lessons or alter friendships to reduce exposure. Behaviour changes can include unusual silence, irritability, avoidance, deterioration in school engagement or unexplained loss of belongings, although none of these signs proves that bullying is occurring. Schools therefore need to avoid relying solely on visible indicators.
Pupils may conceal experiences because they fear retaliation, embarrassment, disbelief, social consequences or loss of access to devices and friendships. Effective responses usually involve listening carefully to the pupil, recording relevant information, assessing immediate safety, investigating appropriately and implementing measures that reduce further harm. Responses should also consider the wider peer environment because bystanders, group dynamics and social norms can either reinforce or interrupt bullying.
Prevention involves more than telling pupils not to bully. Schools can establish clear behavioural expectations, teach respectful relationships, provide trusted reporting routes, supervise higher-risk environments, monitor patterns, train staff and create cultures in which harmful behaviour is challenged. Pupils can be taught how to recognise bullying, support peers safely, report concerns and distinguish responsible help-seeking from retaliation. Staff need to understand that disclosures may be incomplete or hesitant and that apparently minor incidents can form part of a larger pattern.
Families can also contribute information about changes in behaviour or digital activity. Schools may use surveys and incident records to identify locations or groups requiring additional attention. Preventive measures should not place responsibility for safety on targeted pupils, such as requiring them to avoid ordinary school spaces indefinitely. The goal is to modify the environment and behaviour of those creating risk while supporting the pupil who has experienced harm.
Bullying is also significant because it intersects with safeguarding, equality, inclusion and education. Persistent bullying can involve threats, violence, discriminatory harassment, sexual harassment, coercion or exploitation, in which case additional procedures may be required. A school's response should distinguish between accountability for harmful behaviour and support for pupils who may themselves have vulnerabilities or additional needs. A pupil who bullies may require behavioural intervention, education and support, but that does not remove responsibility for the harm caused.
Similarly, restorative approaches can sometimes help repair relationships, but they are not automatically appropriate in every case, particularly where there is a significant power imbalance or risk of further intimidation. The central practical principle is that bullying should be taken seriously as a pattern of harmful behaviour requiring assessment and intervention. Its formal definition may vary, but schools generally need systems capable of identifying, preventing and responding to persistent harmful conduct across physical and digital environments.
