Adverse Childhood Experiences (ACE)

A private, optional reflection on ten categories of experiences before age 18. Skip this test if revisiting childhood feels unsafe today.

Method and research sources

What the ACE score measures

The commonly used short ACE score counts ten categories of abuse, neglect, and household challenges before age 18. It is a retrospective exposure count, not a symptom test.

How scoring works

Each yes adds one point, producing a total from 0 to 10. The original ACE study derived categories from several survey items; this page uses the widespread ten-question shorthand, not the broader WHO ACE-IQ.

Questions about ACE

Does a score of four mean I have PTSD?

No. ACE counts childhood exposure categories; PTSD requires a separate symptom-based clinical assessment.

Can a low score still matter?

Yes. One experience may have a major impact, and important forms of adversity are not included in these ten categories.

Should I share my score?

Only if you choose. You can discuss particular effects or needs without disclosing every event or a score.
