Restrictive intervention policy is now a behaviour-culture issue

Restrictive intervention policy is now a behaviour-culture issue

We were asked recently what the April 2026 DfE guidance really changes for schools. The answer is not simply “more paperwork”, although the recording and reporting duties are clearly important. The bigger point is this: restrictive intervention can no longer sit in a dusty policy folder and only appear after something has gone wrong.

It now has to be part of the way a school thinks about behaviour, safety, staff confidence, SEND support, parent communication and governance oversight.

That may sound obvious. But in many schools the “reasonable force” policy is treated like an emergency document — necessary, serious, but separate from the everyday work of teaching and behaviour leadership. The 2026 guidance makes that separation harder to defend.

The guidance is explicit that restrictive interventions, including reasonable force, restraint and seclusion, may sometimes be lawful where safety is at stake. But it is equally clear that schools should minimise their use through prevention, de-escalation and environmental strategies. So the policy is not just a legal backstop. It is a behavioural standard.

Gary Klugiewicz, founder of Vistelar and a long-standing influence on our work at Dynamis, often talks about the importance of professional contact standards. In plain English: people need to know what “good” sounds like and looks like before the situation becomes dangerous. That applies just as much in a corridor outside Year 9 maths as it does in any other high-risk public-facing role.

A useful way to think about this is as a five-part ladder:

1. Prevention: What are we doing to reduce known triggers and predictable flashpoints?

1. Early de-escalation: What do staff do in the first minute of rising tension?

1. Decision-making: How do staff test necessity, proportionality and pupil welfare?

1. Last-resort intervention: If force is required, is it lawful, necessary and as brief as possible?

1. Post-incident learning: What do we record, report, review and change?

The mistake is to treat only step 4 as the “reasonable force” issue. In reality, steps 1, 2, 3 and 5 are where most of the school’s culture is revealed.

For head teachers and behaviour leads, the practical question is not “Do we have a policy?” It is “Can our staff explain the policy in the language of daily practice?”

Can a classroom teacher say what they should try before force is even considered? Can a teaching assistant describe how they should support a distressed SEND pupil without accidentally escalating the situation? Can the pastoral lead explain when a hold becomes a restrictive intervention? Can the senior leader explain to parents why a decision was necessary and proportionate?

If the answer is no, the policy is not yet operational.

The DfE guidance also places weight on recording and reporting. That matters because records are where the school explains its decision-making. A good record is not a defensive novel written after the event. It is a clear account of necessity, proportionality, welfare considerations, injuries, support and what will be reviewed next.

In other words: your records should show your culture.

A school that takes prevention seriously will record de-escalation attempts. A school that takes SEND seriously will record known triggers, reasonable adjustments and communication needs. A school that takes staff wellbeing seriously will record support and debriefing. A school that takes governance seriously will analyse patterns rather than treating each incident as isolated.

There is a risk here for schools that buy “one-and-done” training and hope it solves the problem. The guidance does not ask whether staff once attended a course. It asks, in effect, whether the school has a credible system: policy, training, risk assessment, recording, reporting, review and oversight.

That does not mean every school needs an over-engineered framework. It means the basics must be clear enough to survive stress.

A simple starting point would be to ask your leadership team three questions:

1. What are the most common situations in our school where staff feel unsafe or unsure?

1. What do we expect staff to do before, during and after those incidents?

1. How do we know whether our current training and policy are actually working?

If those questions produce vague answers, that is your gap.

The DfE guidance is not just a compliance document. It is a prompt to build a safer, more consistent behaviour culture: one where staff are not left improvising under pressure, pupils are treated with dignity, parents are informed properly, and leaders can show their working.

I hope the above helps. If you are reviewing your restrictive intervention policy this year, start with the culture question, not the document. The document matters — but only if staff can use it when the corridor is noisy, the classroom is tense, and a real decision has to be made.
