KCSIE 2026 and Serious Violence: New Duties on Weapons and Peer Conflict

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 — moving this from implicit good practice to an explicit statutory expectation.

The New Weapons-Reporting Duty

KCSIE 2026 confirms a new duty covering how schools record and report incidents involving weapons on or connected to school premises. The precise reporting threshold and process are set out in Part One of the final document — schools should refer to the official GOV.UK text for the exact wording rather than a summary (see Part One, KCSIE 2026).

What is already clear is the direction of travel: schools will be expected to have a consistent, documented process for recording weapons incidents, escalating them appropriately, and ensuring the information reaches the right people — the DSL, senior leadership, and where relevant, the police and children's services. This duty sits alongside, not instead of, 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

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

1. Review your weapons and behaviour policy to confirm it includes a clear recording and escalation process, ready to be aligned with the final KCSIE 2026 reporting requirement once published.
2. Update your child-on-child abuse policy to explicitly name serious violence, misogyny and AI-generated imagery.
3. 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.
4. 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.
5. Cross-reference your PSHE/RSHE curriculum to ensure serious violence and misogyny are addressed directly, not just as part of general anti-bullying content.
