Understanding the three levels of Autism Spectrum Disorder (ASD) can help parents better understand the type and amount of support their child may need. These levels are not about a child’s intelligence or potential — they simply describe how much support a person may need in daily life. Every child with autism is unique. 💙

Children with Level 1 autism may appear more independent but still need support in certain areas.
Common characteristics:
• Difficulty starting or maintaining conversations
• Challenges with social interactions or making friends
• Preference for routines or specific interests
