“Adverse Childhood Experiences”, usually shortened to ACEs, are stressful or traumatic events that happen before the age of 18. Decades of research show that the more adversity a child faces, the greater the impact on their health, behaviour and life chances. For anyone caring for vulnerable children, understanding ACEs is essential, and it sits at the heart of trauma-informed practice. But so is understanding that they do not seal a child’s fate.
What Are ACEs?
The term comes from a large 1990s study by the US Centers for Disease Control and Kaiser Permanente. Researchers found a strong link between difficult childhood experiences and later problems with physical health, mental health and relationships. ACEs are now a widely used framework in social care, education and healthcare across the UK.
The Ten Adverse Childhood Experiences
ACEs are usually grouped into three categories:
Abuse
Physical abuse
Emotional abuse
Sexual abuse
Neglect
Physical neglect
Emotional neglect
Household dysfunction
A parent with a mental illness
Domestic violence in the home
A household member in prison
A parent with drug use
Parental separation or divorce
What Is an ACE Score?
An ACE score is simply a count of how many of these ten experiences a person has had, one point for each, giving a score from 0 to 10. A higher score signals a higher level of early adversity. It is a useful awareness tool, but it is a blunt one: it does not measure how severe each experience was, how long it lasted, or what support the child had. It should never be used to label a child or to predict their future.
How ACEs Affect Children
Living with chronic stress affects the developing brain and body. Children with several ACEs are more likely to struggle with emotional regulation, attention, trust and relationships, and are at higher risk of physical and mental health problems later in life. Many behaviours that look like defiance or disengagement are better understood as survival responses learned in an unsafe environment, a pattern we explore in our guide to the window of tolerance and to childhood trauma.
Why ACEs Are Not Destiny
This is the most important part of the picture. The harm caused by adversity can be buffered, and even reversed, by protective and compensatory experiences: at least one stable, caring adult; a sense of belonging; routine; and opportunities to feel competent and valued. Safe relationships are the single biggest factor in helping a child recover.
How Welcare Supports Children with High ACE Scores
Almost every child who comes into our care has experienced multiple ACEs. Welcare’s response across our therapeutic care homes is to provide exactly the protective experiences the research points to: consistent, trusted relationships with trained staff, predictable daily routines, and support from our in-house therapists. We use approaches such as PACE therapeutic parenting and therapeutic parenting, and where helpful cognitive behavioural therapy. Rather than reacting to surface behaviour, our staff are trained to ask “what happened to this child?” and to build the safety that allows recovery to begin.
Final Thoughts
Adverse Childhood Experiences help us understand why early trauma has such a lasting impact, and why so many looked-after children carry it. But an ACE score is a starting point, not a prediction. With safe relationships and the right support, children with high ACE scores can and do go on to thrive.
Frequently Asked Questions (FAQs)
They are potentially traumatic events that occur in childhood, grouped into abuse, neglect and household dysfunction, which research links to poorer long-term health and wellbeing.
Physical, emotional and sexual abuse; physical and emotional neglect; and five forms of household dysfunction, parental mental illness, substance misuse, domestic violence, a household member in prison, and parental separation or divorce.
There is no "pass" or "fail". A score simply counts how many of the ten experiences a person had. A higher score indicates more early adversity, but it does not measure severity or the support a child received.
Yes, to a significant degree. Stable, caring relationships and positive experiences (sometimes called PACEs) can buffer the impact of adversity and support recovery.
Most children in residential care have experienced several ACEs. Understanding this helps carers respond to behaviour with empathy and provide the protective relationships that aid healing.
