Free ACEs Test Online — Adverse Childhood Experiences Score & Interpretation
The ACEs questionnaire was developed through the landmark 1998 CDC-Kaiser Permanente study (Felitti et al.) involving 17,000+ adults. It identifies 10 categories of childhood adversity and produces an ACE score from 0 to 10 with interpretation. Takes under 2 minutes. You may skip any question at any time.
| ACE Score | Level | Clinical Significance |
|---|---|---|
| 0 | No reported adversity | Lowest risk level; building resilience benefits everyone |
| 1 – 3 | Low to moderate | Modest elevation in risk; protective factors play a key role |
| 4 – 5 | High adversity ← cut-off | Clinically significant threshold; substantially increased risk |
| 6+ | Very high adversity | Multiple serious adversities — trauma-informed support recommended |
Before you begin
This questionnaire asks about potentially difficult childhood experiences including abuse, neglect, and household dysfunction. Revisiting these memories can evoke strong emotional reactions. You may skip any question or exit at any time — this is entirely your choice.

ACE Score Reference (Felitti et al., 1998)
| 0 | No reported adversity | Lowest risk |
| 1–3 | Low to moderate adversity | Modest elevation in risk |
| 4–5 | High adversity ← cut-off | Significantly increased risk |
| 6+ | Very high adversity | Multiple serious adversities |
ACE Score 4+ — Health Risk Context (Felitti et al., 1998)
The original CDC-Kaiser study found that compared to adults with ACE score 0, those with score 4+ had significantly increased risks: depression (+460%), attempted suicide (+1,220%), chronic lung disease (+390%), hepatitis (+240%), heart disease and stroke (elevated). Smoking, substance use, and risky behaviors were also substantially elevated.
These are population-level statistical associations — not individual predictions. Many people with high ACE scores do remarkably well. Protective factors powerfully modify risk: even one stable, supportive relationship during childhood can substantially buffer ACE effects. Healing is possible at any age.
An ACE Score Is Not Destiny
Neuroplasticity — the brain's ability to form new pathways — means healing is possible throughout life. Evidence-based paths include trauma-informed therapy (EMDR, trauma-focused CBT), secure relationships, mindfulness and somatic practices, and community support. Research on Positive Childhood Experiences (PCEs) shows that even one or two protective factors — a trusted adult, a sense of belonging — significantly reduce the health impact of adverse experiences.
Support Is Available
If revisiting these experiences has caused distress, or if your score concerns you, professional support can help. You do not need to carry this alone.

Adverse Childhood Experiences (ACEs): Score Interpretation & Health Outcomes
The Adverse Childhood Experiences (ACE) Study was conducted by Vincent Felitti, Robert Anda, and colleagues at the CDC and Kaiser Permanente, published in 1998 with data from over 17,000 adults. It remains one of the most significant public health studies in history — establishing a clear dose-response relationship between childhood adversity and adult health outcomes across physical and mental health domains. The ACEs questionnaire identifies 10 categories of adversity before age 18 and produces a cumulative score from 0 to 10.
What Are the 10 ACE Categories?
The 10 ACE categories span three domains. Abuse includes emotional abuse (being insulted, sworn at, or humiliated by an adult), physical abuse (being hit, beaten, or physically hurt), and sexual abuse (unwanted sexual contact). Neglect includes emotional neglect (not feeling loved or special) and physical neglect (not having enough food, wearing dirty clothes, no one to protect you). Household dysfunction includes witnessing domestic violence, living with someone who had substance use problems, living with someone who was mentally ill or suicidal, parental separation or divorce, and having a household member go to prison.
ACE Score 4+ — The Clinically Significant Threshold
The original CDC study identified a score of 4 or higher as a clinically significant threshold where risks increase substantially. Compared to adults with ACE score 0, those with score 4+ showed markedly elevated risk for depression (460% increase), attempted suicide (1,220% increase), chronic pulmonary lung disease (390% increase), hepatitis (240% increase), and heart disease. These are population-level associations — not individual predictions. The dose-response relationship means that higher scores correlate with greater cumulative risk, but many people with high ACE scores thrive due to protective factors and resilience.
Protective Factors and Resilience: What the ACEs Test Doesn't Measure
The ACEs questionnaire measures adversity, not resilience. Research on Positive Childhood Experiences (PCEs) shows that protective factors powerfully buffer ACE effects: even one stable, nurturing adult relationship during childhood can substantially reduce the health impact of adversity. Resilience is not fixed — it builds throughout life through secure relationships, community connection, trauma-informed therapy (EMDR, trauma-focused CBT, somatic approaches), and mindfulness practices. An ACE score is a map of historical risk, not a prediction of your future.
