Adverse Childhood Experiences (or ACEs), can be defined as negative or traumatic events that occur from birth to the age of 17 that impact the mental and physical health of an individual.

Research shows that exposure to ACEs may lead to issues such as mental health conditions, chronic physical health conditions and/or substance abuse.

Whether an event has a lasting negative impact on an individual depends on many environmental factors. Two children who experience the same traumatic event may have different responses depending on many things. For example, the impacts of the event may differ depending on when the event took place during childhood, their support system, and access to mental health resources.

The following list includes some of the most common traumatic events impacting children from ages 1-17:

Violence

Abuse (physical, emotional or sexual)

Neglect

Loss of a friend or family member

Missing parental figures or divorce

Other traumatic experiences that can have long-term effects on a child include:

A disrupted living situation

Lack of access to healthcare

Financial challenges

Being unhoused or moving frequently

Discrimination

In summary, it's very important for educators to understand the impact of ACEs in their classrooms. These events shape the behavior and well-being of our students, and can sometimes impact their ability to learn, therefore without studying the impact of ACEs, teachers will not be able to effectively teach their learners. The next slide will outline just how prevalent ACEs are in the United States.

Considerations for Younger Students

The following list should not be used as the only form of assessment, but these behavioral observations can be considered "red flags" or warning signs that your student may have experienced one or more ACES:

Fear of other people

Difficulty sleeping or frequent nightmares

Bedwetting

Changes to their mood

Difficulty showing affection towards friends or family

Avoiding situations or events that relate to a traumatic experience

Difficulty learning in school

Communication with pediatricians (with parental consent) can also help educators gain a fuller picture of a students' background.

Older Students/Teens Self-Reporting Assessment (w/ parental consent)

For older students, the following assessment can be administered to determine exposure to ACEs:

Risk Factors

The following individuals are at a higher risk for experiencing ACEs:

females

individuals from minority groups

children who have experienced financial hardships

children of parents/caregivers who experience high levels of stress

children who have family members or caregivers who struggle with substance abuse or a mental health condition

Lasting Impact on Health & Well-being

According to the CDC, exposure to ACEs can lead to many negative life outcomes. These outcomes relate to health outcomes in childhood and overall life opportunities into adulthood.

Impact on children (short-term)-

Impact on immune system and stress response system

Toxic stress impacts brain functions that support attention/focus, decision making, and learning.

Difficulty sustaining healthy relationships

Impact on teens/adults (long-term)-

Increased risk for injury, sexually transmitted diseases, and involvement in sex-trafficking

Risk of teen pregnancy, pregnancy complications, and fetal death

Limited post-secondary educational experience

Job instability, poor socio-economic status

Racial discrimination due to lack of educational experiences

Cancer, depression, diabetes, heart disease, & suicide

What are the protective factors that can prevent children from experiencing ACEs?

# data[].attributes.body
According to the CDC, the following family factors can protect students from experiencing ACEs during childhood:

families who create a safe and consistent environment

when both the child and family have friendships and connections with peers

children who do well in school

children who have caring adults outside of the family who serve as mentors/role models

families where caregivers make sure basic needs are met (food, shelter, health services)

families where caregivers have college degrees and stable employment

families who enforce rules, and closely monitor and supervise their children

families who work out their challenges peacefully, and help children to resolve their conflicts

families who do fun, positive activities together

families who encourage the importance of school for their children

The following community factors can prevent exposure to ACEs:

when families have access to economic and financial help

when families have access to medical care and mental health services

access to safe, stable housing

access to nurturing and safe childcare, preschools, and after-school programs

where families have employment opportunities with family-friendly policies

when communities have strong partnerships between the community and business, health care, government, and other sectors

when community members feel connected to each other

when violence is not tolerated or accepted in the community

How does a higher ACE score impact brain functioning and development?

How does a higher ACE score impact brain functioning and development?

Trauma has a greater impact on individuals when it occurs during early-childhood as opposed to adolescence and/or adulthood.

"Specifically, ACEs target a child’s memory (hippocampus) and areas of the brain that help them think logically (prefrontal cortex) and process emotions (amygdala). Severe or long-term stress places these parts of a child’s brain into survival mode for too long. This can weaken those parts of their brain and influence the way they react to certain situations as they grow into an adult."

When children are exposed to traumatic events, their brain develops and functions differently. As the brain experiences stress, it releases hormones to adapt to the situation. The fight/flight/freeze response is activated and processes external stimuli.

After a child's stress-response system becomes sensitized, the brain will constantly release these hormones in similar situations, even if it is maladaptive (Cleveland Clinic, 2025).

For example, if a child frequently experiences domestic violence at home, her brain will be stuck in a stress-response state. She will eventually make a connection in her brain between adults and danger. This will generalize to her perceptions of adults at school, too. Therefore, she may be fearful and hypervigilant in the classroom, making it difficult to pay attention.

Here's another example of how a student may respond in the "freeze" or dissociation state in the classroom:

A boy did not finish his work in class, so he is asked to stay after for a few minutes to finish it. After a few minutes, the teacher checks in on him, and he is "zoned-out," and seems unresponsive. The teacher may believe he is being defiant, however the boy has experienced sexual abuse, and being alone with the teacher has activated his stress-response. The boy enters a state of dissociation any time he is alone with a male adult, because that is how he responded, and survived, during the abuse. You can see here how behaviors that were adaptive during traumatic events become maladaptive in the classroom.

Abide by the rules of the brain - Teachers should consider the 3 R's when addressing student behavior (regulate, relate, reason). In order to reason with a child, they first need to be regulated. Then, we will be able to relate with them, and finally reason with them. Without regulation, the parts of the brain used for reasoning will not be "open for business ("Stress, Trauma, and the Brain," 2020).

"Dosing" small levels of "stress" each day - Students who have experienced trauma can be stuck in the fight/flight/freeze state, especially in the school-setting. By slowly exposing them to small levels of stress (such as a consistent morning greeting), we will slowly help their brain make new connections. These doses should be predictable and consistent. For example, a teacher may let a student know that they will check in with each other for one minute every morning upon arrival. Over time, the student will be more tolerable of this interaction, and will start to form a connection with the adult that allows them to feel safe in the classroom.

Let your students determine the "dosing" of therapeutic experiences. I learned in Dr. Perry's The Boy Who Was Raised as a Dog, that connecting with students takes time. They will not feel safe with you if you force them to share information or build a relationship before they are ready. When I implemented the 2x10 intervention with one of my students this year, we spent a few days just doing a puzzle together. Over time, we started to have some small talk during our puzzle time. By the end of the intervention, he was fully opening up to me. Teachers need to earn their students trust through micro-interactions each day.

Rhythmic Exercises - Often times, students who have experienced trauma during childhood have disorganized brainstems and diencephalons. Research shows that activities that mimic heartbeat and breathing can help regulate these lower-brain regions. Some examples include walking, rocking, drumming, and passing a ball back-and-forth.

As the teacher, take care of yourself first! A teacher's mental health and ability to self-regulate is by far the most important way to teacher students impacted by trauma. Emotions are contagious, and our students respond to situations based on our reactions. There's a famous quote by L.R. Knost that states, "When little people are overcome by big emotions, it is our job to share our calm, not join their chaos." By regulating ourselves, even when students are testing us with certain behaviors, we will build their trust and ensure a climate of safety.

Ways teachers can ensure they are regulated throughout the school day:

Get enough sleep

Eat throughout the school day (DON'T. SKIP. LUNCH).

Exercise regularly

Devote time for social engagement and hobbies

The CDC recommends that parents talk to their children about mental health, and support them in managing their emotions.

Parents can positively impact their child's social-emotional development by praising their child frequently. They also recommend that parents take parenting classes in order to gain more tools for raising a healthy and happy child.
