Autism: where speech, occupational, and physical therapy fit, in CDC’s words
CDC groups autism spectrum disorder (ASD) treatments into categories and calls speech and language therapy “the most common developmental therapy for people with ASD.” It describes occupational therapy as teaching skills for living as independently as possible, and physical therapy as improving physical skills. CDC’s early intervention page says those services may include speech, physical, and occupational therapy for eligible babies and young children. This page quotes CDC.

How CDC describes treatment
CDC states: “Current treatments for autism spectrum disorder (ASD) seek to reduce symptoms that interfere with daily functioning and quality of life.” And: “Treatments can be given in education, health, community, or home settings, or a combination of settings.” It lists behavioral, developmental, educational, social-relational, pharmacological, psychological, and complementary and alternative approaches, and notes that some treatments involve more than one.
CDC says: “Behavioral approaches have the most evidence for treating symptoms of ASD.” And: “Developmental approaches are often combined with behavioral approaches.”
Speech and language therapy
CDC states: “The most common developmental therapy for people with ASD is speech and language therapy.” It adds: “Speech and language therapy helps to improve the person's understanding and use of speech and language.” And: “Some people with ASD communicate verbally. Others may communicate through the use of signs, gestures, pictures, or an electronic communication device.” Communication devices are on AAC.
Occupational therapy
CDC states: “Occupational therapy teaches skills that help the person live as independently as possible.” “Skills may include dressing, eating, bathing, and relating to people.” It adds that occupational therapy can also include “Sensory integration therapy to help improve responses to sensory input that may be restrictive or overwhelming.”
Physical therapy
CDC states: “Physical therapy can help improve physical skills, such as fine movements of the fingers or larger movements of the trunk and body.”
Early intervention and school services
CDC’s early intervention page says early intervention “May include speech therapy, physical therapy, occupational therapy, and other types of therapies or services based on the needs of the child and family.” It states: “Eligibility for early intervention services is based on an evaluation of your child's skills.” And: “Each state, territory, or commonwealth has its own early intervention program and rules about eligibility and services.” It also says: “A doctor's referral is not necessary.” For children 3 and older, it tells parents to call a local public elementary school and ask for an evaluation for preschool special education services.
The federal rules behind those services are on IDEA Child Find and IEPs and IFSPs.
What this page does not do
It does not rank treatments, recommend any approach for any child, or say how often therapy should happen or who pays for it. It is not legal, medical, billing, or immigration advice. Confirm current rules with the agency or organization that publishes them, your employer, and your state board.
