KCSIE 2026 and Serious Violence: New Duties on Weapons and Peer Conflict
Two confirmed KCSIE 2026 serious violence changes have direct implications for every DSL: a new duty on recording and reporting weapons-related incidents, and a broadened definition of child-on-child abuse that explicitly names serious violence. This guide explains both, and how they connect to your existing knife crime and behaviour procedures.
ā ļø In force from 1 September 2026. KCSIE 2025 applies until then.
These changes form part of KCSIE 2026 , replacing KCSIE 2026 on 1 September 2026 . Existing statutory duties, including the Serious Violence Duty and the Offensive Weapons Act 2019, continue to apply in the meantime. This is not an exhaustive summary; see Part One, KCSIE 2026, and the full document on GOV.UK ā for the complete wording.
Why Serious Violence Gets New Attention in KCSIE 2026
Knife crime and peer-on-peer violence have been a growing concern for schools for several years, addressed until now mainly through the general safeguarding framework, the Serious Violence Duty, and behaviour policy. KCSIE 2026 responds by naming serious violence directly within the child-on-child abuse definition and introducing a dedicated duty on how schools handle weapons-related incidents. This moves the issue from implicit good practice to an explicit statutory expectation.
The New Weapons-Reporting Duty
KCSIE 2026, paragraph 49 , sets out the duty directly: any member of staff who has a concern about a child carrying or using a weapon, or expressing an intention to do so, should report it to the DSL or a deputy . The DSL then assesses the risk and takes appropriate action.
Paragraph 49 is not a mandatory external reporting duty triggered automatically every time a weapon is found on premises. It is a duty to report to the DSL, who exercises professional judgement about whether the police, children's services or other agencies should be involved. That is consistent with how KCSIE treats other welfare concerns: the DSL as the assessment and decision point, not a passive relay to external agencies. This duty sits alongside existing obligations such as:
- The statutory Serious Violence Duty (introduced under the Police, Crime, Sentencing and Courts Act 2022), which requires local partners including schools to share information to prevent serious violence
- Behaviour policy and exclusion procedures for weapons-related incidents
- Existing safeguarding referral routes to MASH or children's services where a pupil's welfare is a concern
For the wider statutory and prevention context, see our knife crime prevention hub , and our existing article on understanding youth knife crime .
ā ļø A weapon on site is a safeguarding matter, not only a behaviour matter
A pupil carrying a weapon is very often also a pupil at risk: of criminal exploitation, county lines involvement, or retaliatory violence. The new KCSIE 2026 recording duty should be treated as an addition to your safeguarding response, not a replacement for asking why the weapon was there in the first place. See our guide to county lines exploitation for the exploitation context that frequently underlies weapon-carrying among children.
Child-on-Child Abuse: A Broader Definition
KCSIE 2026 expands the child-on-child abuse definition to explicitly name three additional categories alongside the existing list (which already includes bullying, sexual violence and harassment, and initiation/hazing violence):
| New category | What it covers |
|---|---|
| Serious violence | Weapon-related and other serious physical violence between pupils, including incidents linked to gang or group affiliation |
| Misogyny | Misogynistic language, harassment and "incel"-influenced attitudes and behaviour between pupils. See our misogyny and incel culture briefing . |
| AI-generated imagery | Deepfakes and nudification-app images created by one pupil of another. See our AI and deepfakes guide . |
The practical effect is that a child-on-child abuse policy written before these changes will likely be too narrow. Policies should be reviewed to ensure they name these categories directly, set out a zero-tolerance position consistent with KCSIE 2026, and give pupils accessible ways to report concerns about a peer.
How This Connects to Existing Statutory Duties
Nothing in KCSIE 2026 replaces the existing framework schools already work within. The Serious Violence Duty requires local specified authorities, including schools, to work together and share information to prevent and reduce serious violence in their area. The Offensive Weapons Act 2019 and related retailer and possession offences remain the relevant criminal law framework. What changes is that KCSIE now makes explicit what many DSLs were already doing informally: treating weapon-related incidents and serious peer violence as safeguarding matters requiring formal recording, escalation and multi-agency awareness, not solely a school discipline issue.

What to Do Now
- Review your weapons and behaviour policy to confirm it names paragraph 49 of KCSIE 2026 and includes a clear process for any member of staff to report concerns about a child carrying, using, or expressing an intention to use a weapon to the DSL or deputy, who then assesses the risk and acts.
- Update your child-on-child abuse policy to explicitly name serious violence, misogyny and AI-generated imagery.
- Check your reporting pathways so a weapons incident automatically triggers both a safeguarding review (why was the pupil carrying it?) and, where relevant, a Serious Violence Duty information-sharing step.
- Brief pastoral staff that weapon-carrying and serious peer violence should prompt the same "professional curiosity" as other safeguarding indicators. See our professional curiosity guide .
- Cross-reference your PSHE/RSHE curriculum to ensure serious violence and misogyny are addressed directly, not just as part of general anti-bullying content.
Frequently Asked Questions
What is the new weapons-reporting duty in KCSIE 2026?
Paragraph 49 of KCSIE 2026 requires any member of staff who has a concern about a child carrying or using a weapon, or expressing an intention to do so, to report it to the DSL or a deputy. The DSL then assesses the risk and takes appropriate action. It is not an automatic mandatory external reporting duty: the DSL decides what action to take, including whether to involve the police or children's services.
How does KCSIE 2026 change the child-on-child abuse definition?
It explicitly adds serious violence, misogyny and AI-generated imagery to the existing categories such as bullying and sexual violence.
Does this replace existing knife crime procedures?
It sits alongside the Serious Violence Duty and existing safeguarding referral routes. Schools should integrate it into current procedures rather than build a parallel process.
Who should we contact if a weapon is found on site?
Call 999 if there is immediate danger, or 101 for non-emergency police reporting, follow your weapons/behaviour policy, and make a safeguarding referral to MASH where a child's welfare is a concern.
