Harmful Sexual Behaviour in Residential Care: Holding Complexity Without Looking Away

When a young person in residential care displays harmful sexual behaviour, the home must do something very difficult: hold the young person as both someone who may have caused harm and someone who has almost certainly been harmed themselves. Most systems are not built for that.

The language matters from the outset, so it is worth being precise. Harmful sexual behaviour — the term used in current guidance, and preferred over earlier phrases like "sexually harmful behaviour" or "sexually abusive behaviour" — refers to sexual behaviours displayed by children and young people that are developmentally inappropriate, may be harmful to themselves or others, and are beyond what might reasonably be expected for their age and understanding. It is distinct from age-appropriate sexual curiosity and exploration. It is distinct from child sexual exploitation, in which children are victims of abuse by adults. And it is distinct from the broader category of peer-on-peer harm, of which it forms one part. The distinction matters because each requires a different response, a different professional framework, and a different understanding of the young person at the centre of it.

Residential children's homes are disproportionately likely to encounter this issue — not because the young people who live in them are more dangerous than others, but because of who residential care houses. Children and young people who have experienced significant trauma, particularly early and repeated sexual abuse, are at elevated risk of displaying sexualised or harmful sexual behaviour. Research consistently shows that the majority of children and young people who display HSB have themselves been the victims of abuse, often sexual abuse. The care population is, by definition, a population in which early adversity is concentrated. A residential home that is surprised when HSB emerges among its residents has not thought carefully enough about the population it serves. A home that is prepared — that has thought about its policy, its staff training, its house culture, and its referral pathways before an incident occurs — is in a fundamentally different position.

Simon Hackett's continuum of sexual behaviour, developed in the early 2000s and still widely used in assessment and training contexts, provides a useful starting framework. At one end sits normal, developmentally expected sexual behaviour — mutual and consensual curiosity between age-peers, private masturbation, age-appropriate interest in bodies and relationships. Further along the continuum, behaviour becomes more problematic: coercive, involving significant age gaps, preoccupied, or distressing to the young person themselves. At the most serious end sits behaviour that is abusive — involving force, significant power imbalance, or explicit exploitation of a more vulnerable child. The value of the continuum is that it resists the binary of "normal" or "abusive" and instead requires professionals to think carefully about where a particular behaviour sits, why, and what it communicates about the young person's internal world and external experiences. Most HSB displayed by young people in residential settings falls somewhere in the middle range of this continuum. That does not make it less serious, but it does mean that the appropriate response is not simply a criminal justice one.

The AIM (Assessment, Intervention and Moving On) framework, developed by the Greater Manchester Harmful Sexual Behaviour Project and now used nationally, provides a structured approach to assessing HSB in children and young people. AIM is not a risk assessment in the traditional sense — it does not produce a score or a category — but a framework for structured professional judgement that considers the young person's development, their sexual knowledge and behaviour, the context of the concerning behaviour, their motivation, and the protective factors present in their environment. It distinguishes between children under twelve and young people aged twelve to eighteen, recognising that the developmental and contextual factors are substantially different. For residential homes, engagement with AIM-trained practitioners — typically from specialist teams within children's services or CAMHS — is an important part of responding well. What AIM is not is a tool for residential staff to apply themselves; it requires specialist training and is part of a multi-agency response, not a substitute for one.

One of the most difficult things about HSB in residential care is the dual reality it creates within a single young person. The young person who has touched another child inappropriately, or who has coerced a peer into sexual activity, is someone who has caused harm. That is true and it matters. It matters for the safety of other children in the home, it matters for the other young person's experience, and it matters for how the home understands what has happened. But almost invariably, that same young person is carrying their own history of abuse, their own experience of having been harmed, their own unprocessed trauma that has shaped their understanding of relationships, bodies, and what is normal. The system is not well designed to hold both of these truths simultaneously. Criminal justice frameworks tend to focus on the harm caused; therapeutic frameworks tend to focus on the trauma experienced. Residential care has to hold both, without collapsing into either, and do so within a physical space where the young person still has to get up in the morning, have breakfast, and share a living room with other residents.

What this means practically is that the home's response to an incident of HSB must be calibrated to do several things at once: ensure immediate safety for any young person who has been harmed or is at risk, respond to the young person who displayed the behaviour in a way that is clear without being punitive, manage information carefully within the home (particularly what other young people know and how they come to know it), initiate the appropriate multi-agency processes, and maintain the therapeutic environment of the home as far as possible. None of these are easy, and some are in tension with each other. The young person who harmed may need to be moved — either temporarily or permanently — to protect other residents. That placement move will itself be experienced as rejection, as punishment, as evidence that they are too broken for anyone to stay with. The residential home cannot prevent the harm of a placement move when one is necessary, but it can choose how it names what is happening and what it does to maintain the relationship with that young person through and beyond the move.

The multi-agency processes triggered by an incident of HSB can feel, from inside a residential home, like a loss of control over something that is fundamentally a relational matter. The police may become involved. A referral to children's services may be required. The Local Authority Designated Officer may need to be notified if a member of staff is implicated in any way, including in having missed warning signs. The MASH (Multi-Agency Safeguarding Hub) may convene a strategy discussion. CAMHS may be asked to assess. All of this is appropriate, and it protects both the young people involved and the professionals around them. But it can also fragment what should be a coherent response — with different agencies focusing on different aspects, speaking different professional languages, and sometimes working in ways that feel adversarial rather than collaborative. The registered manager's job in this context is to coordinate, to keep the young person visible as a whole person across all of these processes, and to ensure that the relational continuity the home can provide is not sacrificed to procedural compliance.

Staff training is not optional here. Residential workers need to be able to identify the difference between age-appropriate sexual behaviour and behaviour that raises concern. They need to know how to respond in the moment — with calm, without dramatising, without shame-inducing language — to a disclosure or an incident. They need to understand what to record and how, why confidentiality is limited in this context, and who needs to be informed. They need to have had the opportunity, before an incident occurs, to think about their own responses to sexuality and sexual behaviour in young people — their own discomfort, their own assumptions, their own potential blind spots. Training that is solely procedural, that tells staff what to do without creating space for the emotional and attitudinal work, will not produce staff who can navigate this territory well. Good training in this area is uncomfortable by design. It requires practitioners to sit with complexity, to examine their reactions, and to develop a professional position that is neither dismissive nor panicked.

The young people who are affected by another resident's HSB also need support, and this is an area where residential homes sometimes underperform. The culture of confidentiality that appropriately surrounds serious incidents can result in a silence that is itself distressing for young people in the home who know something has happened but cannot get clear information. Other residents are not owed a detailed account of what occurred, but they are owed some acknowledgment that something has happened, that adults are dealing with it, and that they are safe. Young people who have themselves experienced abuse may find that an incident in the home triggers their own distress — memories, flashbacks, a sense of unsafety that the home has so far provided. The home's response to HSB must include attention to its impact on the wider group, not only on the two individuals most directly involved.

There is a particular issue around how HSB is recorded and how it follows a young person through the care system. A young person who has displayed HSB may have this recorded in their file in terms that — if read without context — present them as dangerous, as a risk to other children, as someone who cannot safely live alongside peers. These records travel with them from placement to placement. They inform risk assessments for future placements. They can result in a young person being placed in increasingly isolated, restrictive, or institutional settings on the basis of something that happened when they were twelve and for which they have received no therapeutic intervention. The recording of HSB incidents should be factual, contextualised, and forward-looking — noting what happened, what was known about the young person's circumstances and history at the time, what professional assessment said, and what therapeutic response was offered or planned. A record that functions as a list of past dangerous behaviours without any of this context is a record that will be used to restrict a young person's life rather than to understand it.

What residential care can realistically offer young people who display HSB, and what it cannot, is a distinction worth being honest about. Residential homes are not specialist therapeutic settings for HSB. Staff are not trained therapists. The home cannot provide the kind of structured, evidence-based therapeutic intervention — G-MAP, The Safer Lives Programme, the work of organisations like the Lucy Faithfull Foundation — that specialist services offer. What the home can do is something foundational: it can maintain a consistent, boundaried, warm relationship with the young person through the period of assessment and beyond. It can model what safe, non-sexualised relationships look like between adults and young people. It can provide clear and consistent boundaries around sexual behaviour without using shame as the mechanism of enforcement. It can keep the young person connected to education, to activities, to the ordinary texture of adolescent life. It can advocate within the professional network for specialist support to be provided, and can support the young person to engage with that support. None of this is nothing. In fact, for many young people, it is everything.

The residential home that responds well to HSB is not the home that never encounters it — that is largely a matter of chance and cohort. It is the home that is prepared: that has a clear policy, a trained workforce, a culture in which staff can raise concerns early and without fear, and a leadership that understands both the complexity of the issue and the importance of the relational continuity the home provides. It is also the home that can hold, without flinching, the hardest truth in this area: that the young person who has harmed someone else is still a child, still a person who deserves care and therapeutic support, and still someone whose life has not been determined by what they did on one day in one place. The capacity to hold that truth — to remain present to a young person who has done something difficult while also taking seriously the harm they caused — is not a weakness or a naivety. It is one of the most demanding things residential care asks of its practitioners, and one of the most important.
