What Is Autism?
Quick Answer
Autism is a difference in how a person's brain works that affects how they communicate, interact with others, and experience the world around them. People with autism might find certain sounds, textures, or social situations harder to deal with, but they also often have unique strengths and interests. Autism is not a disease -- it is simply a different way of being.
Explaining By Age Group
Ages 3-5 Simple Explanation
You know how every person is different? Some people have brown hair, some have blonde. Some people like loud music, some like it quiet. Well, some people's brains work in a different way, and that is called autism.
Kids with autism might not like to be hugged, or loud noises might bother them a lot. It's like when a tag on your shirt scratches you and it drives you crazy -- for some kids with autism, lots of things feel like that scratchy tag.
Some kids with autism might play by themselves or talk about the same favorite thing over and over. That does not mean they do not want friends. They just show it in a different way than you might be used to.
If you know someone with autism, you can be kind to them by being patient. Play with them, talk to them, and know that even if they seem different, they have feelings just like you do.
Ages 6-8 More Detail
Autism is something that makes a person's brain work differently from most other people's brains. It is not a sickness and you cannot catch it. A person is born with autism -- it is part of who they are, like having brown eyes or being tall.
Kids with autism might have a harder time with some things that feel easy to you. They might not understand jokes or sarcasm. They might have trouble looking people in the eyes during a conversation. They might not know what to say in social situations that feel natural to you.
But autism also comes with strengths. Many kids with autism are super focused on things they love and know an incredible amount about their favorite subjects. They might notice details that everyone else misses. They are often very honest and loyal friends.
Some kids with autism are very sensitive to things like loud noises, bright lights, certain textures, or big crowds. Imagine if the volume on all your senses was turned way up -- that is what it can feel like. A school cafeteria might feel totally normal to you but overwhelming to a kid with autism.
Every person with autism is different. Some kids with autism talk a lot, some talk a little, and some use other ways to communicate. Some need a lot of extra help, and some do not. There is a saying: 'If you have met one person with autism, you have met one person with autism.' It means everyone with autism is unique.
The most important thing is to be kind and include kids with autism. They want to be part of things just like everyone else. If a classmate has autism, try to be patient, include them, and get to know them. You might be surprised how awesome they are.
Ages 9-12 Full Explanation
Autism -- sometimes called Autism Spectrum Disorder or ASD -- is a brain difference that affects how a person communicates, connects with others, and experiences their environment. It is called a 'spectrum' because it looks really different from person to person. Some people with autism need a lot of daily support, while others live independently and you might never guess they have it unless they told you.
The social side of autism is often the most visible. Many people with autism find it harder to read facial expressions, understand tone of voice, or pick up on the unwritten social rules that most people learn automatically. Think about how you just know when someone is being sarcastic, or when it is your turn to talk, or when someone wants to be left alone. For people with autism, those signals can be confusing or invisible. That does not mean they do not care about people -- they just process social information differently.
Sensory experiences can also be very different for people with autism. Sounds, lights, textures, and smells that seem normal to most people can feel intense or even painful. A fluorescent light might not bother you at all, but for someone with autism it might feel like a strobe light. The tag inside a shirt might feel like sandpaper. This is why some people with autism wear headphones, prefer certain clothes, or need to leave crowded places.
One of the coolest things about autism is the way many people with it get deeply into their interests. When someone with autism finds something they love -- whether it is trains, space, art, animals, coding, or history -- they often learn everything about it and become a real expert. That deep focus is a genuine strength that leads many people with autism to do amazing work in their fields.
The biggest mistake people make about autism is thinking it is something that needs to be fixed. It is not. People with autism do not have a broken brain -- they have a different brain. Yes, some aspects of life are harder for them, and they deserve support with those things. But the goal is not to make them 'normal.' The goal is to help them thrive as who they are.
If you have a classmate with autism, the best thing you can do is treat them like a person, not a diagnosis. Include them. Be patient when they do not get a joke or say something unexpected. Do not talk about them like they are not in the room. And never use the word 'autistic' as an insult -- that is harmful and wrong. Everyone deserves to be treated with respect, and that includes respecting people who experience the world differently than you do.

Tips for Parents
Autism can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.
DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.
DO: Validate their feelings. Whatever emotion your child has in response to learning about autism, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'
DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'
DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about autism. This makes them more likely to come to you rather than seeking potentially unreliable sources.
Common Follow-Up Questions Kids Ask
After discussing autism, your child might also ask:
Can you tell if someone has autism just by looking at them?
No. Autism is invisible from the outside. You cannot tell by looking at someone whether they have autism. It only becomes noticeable through how a person communicates and interacts.
Is autism a disease?
No, autism is not a disease or an illness. It is a brain difference that a person is born with. You cannot catch it, cure it, or give it to someone else.
Why do some kids with autism not like being touched?
Many people with autism are extra sensitive to physical sensations. A gentle touch might feel overwhelming to them. Always ask before hugging or touching someone, regardless of whether they have autism.
Can people with autism have friends?
Absolutely. Many people with autism want and have close friendships. They might make friends differently or prefer smaller groups, but their desire for connection is just as real.
What should I do if I think I might have autism?
Talk to a parent, school counselor, or doctor about what you have noticed. Getting assessed can help you understand yourself better and get support if you need it.
