Read our full editorial standards →The ACE questionnaire asks about hard things that may have happened before you turned 18, and the result is a single number from 0 to 10. That number can feel heavy. This guide explains what it counts, what research has found, and, just as important, what it cannot tell you about your own future.
At a glance
- The ACE score is a count of up to 10 kinds of adverse experiences before age 18, so it runs from 0 to 10.
- In research, 4 or more is linked with higher health risks across large groups. It is not a prediction for any one person.
- A score describes what happened, not who you are. Positive experiences and supportive relationships are also linked with adult well-being.
What is the ACE score?
ACE stands for adverse childhood experiences. The idea comes from a large 1998 study run with a US health plan: a questionnaire was mailed to 13,494 adults, and 9,508 answered it. The study looked at seven kinds of childhood adversity, including abuse and growing up in a household affected by violence, substance use, mental illness or imprisonment.
The ten-question version used today, and on our check page, covers three areas: abuse (emotional, physical, sexual), neglect (emotional, physical) and household challenges (violence toward a caregiver, a family member with an alcohol or drug problem, a family member with depression or other mental illness, parents separating or divorcing, and a family member going to prison).
How is the ACE score calculated?
- Each question asks whether a specific kind of experience happened before your 18th birthday.
- Yes counts as 1 and No counts as 0.
- Add up the yes answers. The total is your ACE score, from 0 to 10.
The score counts kinds of experiences, not how often or how badly they happened. One very hard experience counts as 1, and so does an experience that happened once. That is one reason the number can never capture the whole story.
ACE score interpretation
| ACE score | How our page labels it | What it means |
|---|---|---|
| 0 | None reported | None of the ten listed experiences were reported |
| 1–3 | Some reported | One to three kinds of adversity were reported |
| 4–10 | Several reported | The range research has linked with higher health risks across groups |
In the 1998 study, more than half of the people who answered reported at least one category, and a quarter reported two or more. People with four or more categories, compared with people with none, had several-fold higher rates of problems such as depression and alcohol or drug use. These are group-level associations. They describe patterns across thousands of people, not what will happen to you.
Many people with a high ACE score live well, and many people with a score of 0 struggle. A score of 0 also does not mean childhood was easy: the questions leave out many hard experiences, such as bullying, loss of a parent or living in an unsafe neighborhood.
Your score is not your destiny
Adversity is only part of the picture. A 2019 study of 6,188 adults in Wisconsin also asked about seven positive childhood experiences: good relationships with family, with friends, and at school or in the community. Adults who reported six or seven of these had much lower odds of depression or poor mental health than adults who reported two or fewer, and this pattern held at every level of adverse experiences.
Relationships and support built later in life matter too. Noticing how old experiences still show up today, in how you react to conflict, how you treat yourself, or how much you trust others, is often where change starts. For trauma-related symptoms specifically, the PCL-5 is a separate check that looks at how you are doing now.
Take the ACE check

It is normal to feel unsettled after answering questions like these. It can help to do something grounding, such as the 5-4-3-2-1 exercise, and to tell someone you trust how you are feeling. If memories of childhood keep weighing on you, a licensed professional can help you work through them at a pace that feels safe.
CareOps Maeumi is an AI counseling app where you can talk about what comes up, by voice or text, and it remembers earlier sessions so you do not have to start over each time. Sign-up and initial self-checks are free; check your account’s session offer and pricing before payment. You can use it alongside care from a licensed professional.
Frequently asked questions
- What is a normal ACE score?
- There is no normal or abnormal score. In the original 1998 study, more than half of adults reported at least one category of adversity. The score is a count of experiences, not a grade.
- What does an ACE score of 4 or more mean?
- In research, 4 or more is the range linked with higher rates of health problems across large groups of people. It does not predict what will happen to any individual, and many people with high scores do well.
- How many questions are on the ACE questionnaire?
- The commonly used version has 10 yes-or-no questions about abuse, neglect and household challenges before age 18. Each yes adds 1 point, for a total from 0 to 10.
- Does the ACE score measure trauma?
- Not exactly. It counts whether certain experiences happened, not how they affected you. It is a screening tool, not a diagnosis. Checks like the PCL-5 look at current trauma-related symptoms instead.
