ACE Score — Adverse Childhood Experiences Assessment
Childhood Trauma Test — ACE Score
This free childhood trauma test is based on the ACE (Adverse Childhood Experiences) questionnaire — developed through the landmark 1995-1997 study conducted by the CDC and Kaiser Permanente involving over 17,000 adult participants, and now one of the most widely cited research instruments in public health and trauma medicine. The ACE questionnaire measures childhood adversity across three domains: abuse (emotional, physical, and sexual), neglect (emotional and physical), and household dysfunction (domestic violence, substance abuse in the home, household mental illness, parental separation, and household member incarceration). Each domain that applies to your childhood experience contributes one point to your ACE score (0-10).
Abuse
Emotional, physical, and sexual abuse before 18
Neglect
Physical and emotional abandonment or inadequate care
Household Dysfunction
Violence, addiction, mental illness, incarceration
ACE Score
Instant scoring with health risk guidance
✓ Based on the validated ACE questionnaire (CDC/Kaiser Permanente)
✓ Used by trauma therapists and public health researchers worldwide
✓ Includes guidance on trauma bonding, religious trauma, and healing pathways

Frequently Asked Questions — Childhood Trauma Testing
What are the ten categories of adverse childhood experiences and why were these specifically chosen?
The original ACE questionnaire assessed ten categories across three domains. Abuse: emotional abuse (being insulted, humiliated, or made to feel afraid by a household adult), physical abuse (being pushed, hit, slapped, or injured), and sexual abuse (unwanted sexual contact from an adult or someone at least five years older). Neglect: emotional neglect (feeling unloved and unsupported by family) and physical neglect (lack of food, clothing, protection, or care). Household dysfunction: witnessing domestic violence against the mother, living with someone who had a substance problem, living with a mentally ill or suicidal household member, parental separation or divorce, and having a household member imprisoned. These categories were chosen because they were the most consistently reported in clinical practice, were measurable through retrospective self-report, and were suspected to have population-level health significance — a suspicion that the study confirmed dramatically.
Why does the ACE questionnaire only ask about experiences before age 18?
The ACE study focused on childhood and adolescence (before age 18) because this developmental period is when the brain, nervous system, and stress response system are most actively forming and therefore most susceptible to lasting alteration by experience. Trauma experienced during development — particularly early childhood — produces different and typically more pervasive effects than trauma experienced by an already-formed adult nervous system, because it shapes the developmental trajectory of systems that are still being built. This does not mean adult trauma is less real or less serious — it means the mechanisms of impact and the required treatment approaches differ. The PCL-5 based PTSD test on this site screens for trauma of any origin, including adult trauma.
My ACE score is high but I feel fine — does the research still apply to me?
The ACE research describes population-level risk associations, not individual destinies. Many people with high ACE scores are functioning well and do not report significant current distress. Several factors explain this: the presence of protective factors (one consistently supportive relationship, access to therapy, strong social support, physical health practices) substantially mitigates the risks. Additionally, some effects of childhood adversity are not experienced as distress but as characteristic ways of relating to the world, managing emotions, or approaching relationships — patterns that may not feel problematic from the inside even when they are causing costs that a person has not yet connected to their history. If you have a high ACE score and feel fine, that is genuinely good news. It may also be worth remaining curious about whether any patterns in your relationships, stress responses, or health have roots you have not yet explored.
What is the difference between childhood trauma and PTSD?
Childhood trauma (as measured by the ACE questionnaire) refers to the adverse experiences themselves — what happened to you before age 18. PTSD is a specific clinical syndrome that can develop as a consequence of traumatic experience — characterised by intrusion symptoms (flashbacks, nightmares, distressing memories), avoidance of trauma reminders, negative alterations in mood and cognition, and hyperarousal. Not everyone who experiences childhood trauma develops PTSD: some develop other trauma-related presentations (depression, anxiety, personality difficulties, chronic physical health problems, attachment difficulties) without the specific PTSD symptom cluster. Complex PTSD (C-PTSD), recognised in the ICD-11, describes the presentation that specifically develops from prolonged, repeated, and inescapable childhood trauma — adding disturbances in self-organisation (emotional dysregulation, negative self-concept, relational difficulties) to the core PTSD symptoms. Our PTSD test screens for current PTSD symptom severity regardless of ACE score.
Can childhood trauma be completely healed, or does it always leave permanent effects?
The research on trauma recovery is genuinely encouraging about the degree of change possible — while also being honest that "healed" for complex childhood trauma rarely means "as if it never happened." What the evidence supports is that the symptoms of childhood trauma — the hypervigilance, emotional dysregulation, relational difficulties, negative self-concept, somatic symptoms, and PTSD-related experiences — respond substantially and often dramatically to appropriate treatment. The neurobiological changes that childhood adversity produces are not permanent because the brain retains plasticity throughout life, and therapeutic experiences that provide new relational experiences, process incomplete trauma responses, and build regulatory capacity can genuinely reorganise the nervous system's baseline. Many people with high ACE scores report that the healing process, while demanding, produced a depth of self-understanding and capacity for authentic connection that they do not think they would have developed otherwise. The trauma becomes part of the story without continuing to be the story.
