The 10 ACEs Explained: Types of Adverse Childhood Experiences
Ever feel like echoes of your childhood still shape your adult self—your relationships, your health, even how you handle daily stress? For many, the invisible threads connecting past and present are woven from what are known as the 10 Adverse Childhood Experiences (ACEs). These are specific, potentially traumatic events that, if experienced before the age of 18, can shape our development and well-being in profound ways.
This guide will walk you through each of the ten ACEs, breaking them down into clear, understandable categories. Learning about these experiences is not about placing blame or dwelling on the past. It’s about gaining clarity, compassion for yourself, and the tools to move forward. If you're ready to connect the dots of your own story, you can begin by taking the confidential ace test online to gain personal insight.
What Are the 10 ACEs? A Foundational Overview
The term "ACEs" represents a scientifically validated concept that has transformed our understanding of trauma and health. Identified through groundbreaking research, these ten experiences provide a common language for discussing childhood adversity and seeing how our early environment created the blueprint for our adult lives.
The CDC-Kaiser Permanente ACE Study: Origins of the Framework
The concept of the 10 ACEs comes from the landmark Adverse Childhood Experiences (ACE) Study, conducted by the U.S. Centers for Disease Control and Prevention (CDC) and Kaiser Permanente in the 1990s. This large-scale investigation surveyed over 17,000 adults about their childhood experiences and current health status. The findings were staggering: they revealed a direct, dose-response relationship between the number of ACEs experienced and the risk for numerous health problems in adulthood, from chronic disease to mental health challenges. This study gave us the ten-question framework used in the standard ACE questionnaire.
Why Understanding Each ACE Matters for Self-Discovery
Recognizing which, if any, of the 10 ACEs you've experienced is a crucial act of self-discovery. It can feel like finding a missing puzzle piece, helping you understand long-standing feelings, behaviors, and even physical health issues. This knowledge empowers you to reframe your narrative from "what's wrong with me?" to "what happened to me?". This shift in perspective is the foundation of healing and building resilience. Understanding your story is the first step, and the free ACE test is a great tool to begin.
The Three Categories of ACEs: Abuse
The first category of ACEs includes experiences where harm was directly inflicted upon a child. These actions can leave both visible and invisible scars, affecting a person's sense of safety, self-worth, and ability to trust others.
Physical Abuse: Understanding Its Definition and Impact
Physical abuse involves being pushed, grabbed, slapped, or having something thrown at you. It also includes being hit so hard that it left marks or caused an injury. Such experiences violate a child's sense of bodily safety and can lead to a state of constant hyper-vigilance, where the nervous system is always on high alert for danger.
Emotional Abuse: The Invisible Scars of Childhood
Often considered one of the most insidious forms of abuse, emotional abuse occurs when a parent or caregiver frequently swears at, insults, criticizes, or humiliates a child. This consistent pattern of verbal assault chips away at a child's self-esteem and sense of worth. Because the wounds are not physical, they are often dismissed, but their impact on mental health can be profound and long-lasting.
Sexual Abuse: Recognizing This Form of Adversity
A deep betrayal of trust, sexual abuse involves a caregiver or another adult forcing or attempting to force a child into any sexual activity. This can range from unwanted touching and fondling to more severe forms of assault, and it can fundamentally alter a person's relationship with their own body, sexuality, and intimacy later in life.
The Two Categories of ACEs: Neglect
The second category of ACEs is defined not by harmful actions, but by the absence of necessary care. Neglect occurs when a child's fundamental needs are not met, creating a different but equally damaging form of trauma.
Physical Neglect: When Basic Needs Go Unmet
Physical neglect occurs when a child's basic needs go unmet, such as not having enough to eat, wearing dirty clothes, or not having a caregiver who protected them or provided medical care. This experience sends a powerful message to a child that their basic survival and well-being are not important, creating a deep-seated sense of insecurity and instability.
Emotional Neglect: The Absence of Care and Connection
Perhaps the most common and least understood ACE, emotional neglect means growing up in a household where you felt unloved, unimportant, or that your family didn't look out for one another. It is the lack of sufficient emotional support, affection, and validation. This can leave a person feeling empty, disconnected, or perpetually lonely, even when surrounded by others. If these experiences resonate, an ACE assessment test can provide clarity.
The Five Categories of ACEs: Household Dysfunction
The final category of ACEs relates to the environment in which a child grows up. These experiences create a stressful and unpredictable home life, forcing a child to adapt to chaotic or frightening circumstances. This is a key part of the adverse childhood experiences list.
Mother Treated Violently: Witnessing Domestic Violence
This form of adversity involves witnessing a mother or stepmother being pushed, grabbed, slapped, or having something thrown at her. It also includes seeing her being kicked, bitten, hit with a fist, or threatened with a weapon. Witnessing domestic violence forces a child into a state of terror and helplessness, fundamentally shaping their understanding of relationships and safety.
Household Substance Abuse: Living with Addiction
This ACE applies if you lived with anyone who was a problem drinker, alcoholic, or used street drugs. Growing up with substance abuse in the home creates an environment of unpredictability, broken promises, and emotional chaos. Children often take on caregiver roles, sacrificing their own childhood needs.
Household Mental Illness: Coping with a Caregiver's Struggles
This ACE is marked by living with a household member who was depressed, mentally ill, or attempted suicide. When a caregiver struggles with their own mental illness in a home, it can be difficult for them to provide consistent emotional and physical care. This can leave a child feeling confused, worried, or responsible for their caregiver's well-being.
Parental Separation or Divorce: Navigating Family Disruption
This ACE is present if your parents were ever separated or divorced. While parental separation is common, it is still a significant disruption to a child's world. It can shatter their sense of family stability and security, forcing them to navigate complex emotional loyalties and changes to their daily life.
Incarcerated Household Member: The Hidden Trauma
The final ACE in the framework involves having a household member go to prison. The trauma of having an incarcerated family member is often accompanied by shame, stigma, and financial instability. It is a sudden and profound loss that is often kept secret, leaving the child to process their grief and confusion in isolation. Taking a childhood trauma quiz can be an initial step to seeing these connections.

Frequently Asked Questions About the 10 ACEs and Your Score
What are the 10 ACEs exactly?
The 10 ACEs are ten specific types of adversity experienced before age 18. They are grouped into three categories: Abuse (physical, emotional, sexual), Neglect (physical, emotional), and Household Dysfunction (witnessing domestic violence, household substance abuse, household mental illness, parental separation/divorce, and an incarcerated household member).
What does my ACE score mean after I take the test?
Your ACE score, which ranges from 0 to 10, is a tally of how many of the 10 ACEs you experienced. It is a screening tool that indicates your level of exposure to early life stress. A higher score is correlated with a higher risk for certain health issues, but it does not determine your future. It's a starting point for understanding your past and building resilience. You can get your ACE score interpretation on our platform.
How accurate is the ACE test as a screening tool?
The ACE test is a highly reliable and scientifically validated screening tool. It is based directly on the questions used in the landmark CDC-Kaiser Permanente study. While it is very accurate for tallying exposure to these specific ten adversities, it is important to remember it is not a medical or psychological diagnosis. It is a powerful informational tool to begin a conversation with a healthcare provider or therapist.
Is a parent dying considered an ACE?
While losing a parent is an incredibly traumatic event, it is not one of the original 10 experiences measured by the standard ACE questionnaire. However, the circumstances surrounding the death could be related to an ACE. For example, if a parent died by suicide (related to household mental illness) or due to substance abuse, those factors would be counted. The ACE framework focuses on specific patterns of abuse, neglect, and household dysfunction.
