Children entering residential care have disproportionately experienced Adverse Childhood Experiences (ACEs). Understanding what ACEs are, how they shape development and behaviour, and how residential teams can respond is fundamental to providing effective, trauma-informed care.
Definition
Adverse Childhood Experiences (ACEs)
Potentially traumatic events that occur in childhood (0–17 years), including abuse, neglect, household dysfunction, and other forms of adversity. The original ACE study identified ten specific experiences, though the concept has since been expanded to include community and systemic adversity.
The Original Ten ACEs
The landmark ACE study, conducted by the CDC and Kaiser Permanente in the late 1990s, identified ten specific adverse experiences that were strongly correlated with long-term health and social outcomes. These are grouped into three categories:
| Category | Adverse Experience |
|---|---|
| Abuse | Physical abuse |
| Emotional abuse | |
| Sexual abuse | |
| Neglect | Physical neglect |
| Emotional neglect | |
| Household dysfunction | Growing up with a household member who has a substance misuse problem |
| Growing up with a household member who has a mental health difficulty | |
| Witnessing domestic abuse | |
| Losing a parent or caregiver through separation, divorce, or death | |
| Having a household member who is incarcerated |
ACEs are not the whole picture
While the original ten ACEs provide a useful framework, many practitioners now recognise additional forms of adversity, including community violence, poverty, racism, displacement, and systemic disadvantage. In residential care, most children have experienced multiple ACEs alongside other forms of adversity.
How Prevalent Are ACEs in Residential Care?
Research consistently shows that children in residential care have significantly higher ACE scores than the general population. While the original ACE study found that around 10% of adults had experienced four or more ACEs, studies of children in the care system find this figure is often 50% or higher. Most children in residential care have experienced abuse, neglect, family breakdown, or household dysfunction — often in combination.
Why this matters for practice
If you work in residential care, you should assume that every child you support has experienced significant adversity. This does not mean treating every child as fragile or broken — it means understanding that behaviour you see is likely rooted in experiences you may never fully know.
How ACEs Affect Development
ACEs affect children's development in multiple, interconnected ways. Understanding these effects is essential for staff working in residential care, because they explain much of the behaviour that might otherwise seem baffling, challenging, or deliberate.
Brain development
Chronic exposure to stress in childhood — particularly when there is no consistent, protective adult to buffer that stress — affects brain development. The amygdala (the brain's alarm system) becomes overactive, the prefrontal cortex (responsible for reasoning and impulse control) may be underdeveloped, and the hippocampus (involved in memory and learning) can be affected. This means children with high ACE scores may struggle with emotional regulation, impulse control, attention, and learning — not because they are choosing to, but because their brains have been shaped by the need to survive threat.
Attachment and relationships
Many ACEs involve the very people who should have been a child's source of safety — parents, caregivers, household members. When the people who should protect you are the source of harm, it fundamentally disrupts attachment development. Children may learn that adults are unsafe, that relationships are conditional, or that their needs do not matter. In residential care, this shows up as distrust, testing behaviour, pushing adults away, or over-compliance that masks genuine fear.
Emotional regulation
Children who have experienced chronic adversity often have underdeveloped emotional regulation systems. They may swing between emotional extremes, struggle to calm themselves after becoming distressed, or shut down entirely. What looks like an overreaction may be a genuine inability to self-regulate — a skill that was never modelled or developed in a safe, consistent environment.
The ACE Score and Its Limitations
The ACE score — a count of how many of the ten ACEs an individual has experienced — is a useful research tool and can help staff understand the cumulative impact of adversity. However, it has important limitations:
- It does not capture the severity, frequency, or duration of each experience
- It does not account for protective factors — such as a single stable, caring relationship — which can buffer the impact of ACEs
- It does not capture forms of adversity beyond the original ten, such as racism, poverty, or community violence
- A high ACE score is not a destiny — many people with high scores lead healthy, fulfilled lives with the right support
Use ACEs to understand, not to label
ACE scores should inform practice and understanding — they should never be used to label a child, limit expectations, or define their potential. The purpose of understanding ACEs is to respond more effectively, not to categorise children.
How Residential Teams Can Respond to ACEs
Understanding ACEs is only useful if it changes practice. The following principles should guide your response:
Assume adversity
Approach every child with the assumption that they have experienced significant adversity, even if you do not know the details. This shapes how you interpret behaviour — not as deliberate defiance, but as a response rooted in experience.
Focus on safety
The antidote to chronic stress is safety — physical, emotional, and relational. Every interaction should ask: 'Is this making the child feel safer or less safe?'
Prioritise relationships
The single most powerful buffer against the impact of ACEs is a consistent, trustworthy relationship with a caring adult. Staff stability and relationship-building are not soft skills — they are the primary intervention.
Build regulation skills
Children with high ACE scores often need explicit support to develop emotional regulation. This includes co-regulation (staff staying calm and present when children are dysregulated), explicit teaching of regulation strategies, and environments that support regulation.
Avoid re-traumatisation
Practices such as restraint, seclusion, unpredictable consequences, and harsh language can re-traumatise children. Examine every practice through the lens of whether it could trigger a trauma response.
Support staff wellbeing
Working with traumatised children carries a real risk of vicarious trauma. Staff need reflective supervision, emotional support, and permission to look after their own wellbeing — not as an add-on, but as an essential part of the work.
Resilience and Recovery
While the impact of ACEs is significant, it is not irreversible. The brain retains neuroplasticity throughout life — it can heal, rewire, and develop new patterns. The key factors in recovery are:
- Safe, stable, nurturing relationships — the single most important factor
- Consistent, predictable environments that reduce chronic stress
- Opportunities to develop competencies, interests, and a sense of identity
- Access to therapeutic support where needed
- Communities and cultures that value and include the child
"ACEs are not a life sentence. With the right relationships, the right environment, and the right support, children recover, grow, and thrive. Our job in residential care is to be the consistent, caring presence that makes that recovery possible."
- ACEs are prevalent among children in residential care — assume every child has experienced significant adversity
- The original ten ACEs cover abuse, neglect, and household dysfunction, but many children have experienced additional forms of adversity
- ACEs affect brain development, attachment, emotional regulation, and health outcomes
- The ACE score is a useful tool but has limitations — it does not capture severity, protective factors, or resilience
- Residential teams should respond by focusing on safety, relationships, regulation, and avoiding re-traumatisation
- Recovery is possible — the brain retains neuroplasticity, and safe relationships are the most powerful driver of healing
What does ACE stand for in childcare?+
ACE stands for Adverse Childhood Experience. The term comes from a major public health study that identified ten specific adverse experiences — including abuse, neglect, and household dysfunction — that are strongly correlated with long-term health and social outcomes.
Should I ask a child about their ACEs?+
Not directly in a way that feels like an interrogation. The purpose of understanding ACEs is to inform your approach, not to extract a detailed trauma history from a child. Children should share their experiences at their own pace, in their own time, with trusted adults — not on demand.
Can children recover from ACEs?+
Yes. While ACEs have significant impacts, recovery is absolutely possible. The brain retains neuroplasticity throughout life. Safe, stable, nurturing relationships are the single most important factor in recovery. Residential care, done well, can be a powerful context for healing.
How many ACEs do children in care typically have?+
Research varies, but studies consistently show that children in the care system have significantly higher ACE scores than the general population. While around 10% of adults in the general population report four or more ACEs, this figure is often 50% or higher among children in residential care.
