If your child was just diagnosed with autism, you have probably heard two recommendations at once: ABA and speech therapy. Some parents hear that ABA can replace speech therapy. Others hear the opposite. Neither is quite true. The two therapies come from different professions, use different methods and answer to different licensing rules. They often work well together, and the right order depends on your child, not on a general rule.
This guide compares them side by side, explains how Florida insurance treats each one, and gives you a short checklist for deciding where to start.
What does a speech-language pathologist do?
A speech-language pathologist (SLP), often called a speech therapist, is licensed by the state of Florida under Part I of Chapter 468, Florida Statutes. Section 468.1125 defines the practice of speech-language pathology as the prevention, identification, evaluation, treatment and habilitation of "disorders of human communication" and related oral and swallowing skills. The statute lists, among others, disorders of speech, articulation, fluency, voice, "verbal and written language and related nonoral/nonverbal forms of language," cognitive communication and "interactive communication."
In practice, an SLP working with an autistic child may focus on:
- Receptive language: understanding words, directions and questions.
- Expressive language: putting words together, asking for things, telling what happened.
- Speech sounds: articulation and how clearly a child is understood.
- AAC: choosing and teaching an alternative or augmentative communication system, such as picture cards or a speech-generating device.
- Social communication: turn-taking in conversation and reading context.
- Feeding and swallowing: oral motor skills, when that is part of the picture.
The CDC describes speech and language therapy as the most common developmental therapy for people with autism, and says it "helps to improve the person's understanding and use of speech and language."
What does ABA do, and how is it different?
Applied behavior analysis (ABA) is a behavioral approach. The CDC describes behavioral approaches as focusing on "changing behaviors by understanding what happens before and after the behavior." A Board Certified Behavior Analyst (BCBA) assesses your child, writes a treatment plan with measurable goals, and usually supervises a Registered Behavior Technician (RBT) who delivers most sessions. Florida does not license behavior analysts; the credential to look for is BACB certification, which the state recognizes under s. 393.17.
ABA plans often include communication goals, such as asking for help instead of crying, or using a word, sign or device to request a break. That overlap is where the confusion starts. The difference is in focus and expertise:
- An SLP is the specialist in how language and speech work: sounds, grammar, meaning, the motor side of speech, and which AAC system fits a child.
- A BCBA is the specialist in what a behavior does for a child and how to teach a new skill that works better, including practicing communication many times a day across home, school and community.
| Speech therapy | ABA | |
|---|---|---|
| Who designs it | Licensed speech-language pathologist (Fla. Stat. ch. 468, Part I) | BCBA (BACB certification) or a provider licensed under ch. 490 or 491 |
| Who delivers sessions | Usually the SLP | Usually an RBT, supervised by the BCBA |
| Main targets | Language, speech sounds, AAC, social communication, feeding | Daily living, communication, social and play skills, behaviors that cause harm or block learning |
| Typical schedule | Often one or two sessions a week; varies by evaluation and plan | Often several hours a week; payer policies describe ranges from a few hours to 25 or more |
| Where it happens | Clinic, home, school or telehealth | Center, home, school, daycare or community |
| Parent role | Home practice between sessions | Caregiver training is built into most payer requirements |
Which does my child need first?
There is no single right order. Your child's diagnostic report, the SLP evaluation and the BCBA assessment are what should guide the decision, along with your child's doctor. Here are patterns families and clinicians often weigh:
- Speech first, or speech alone, may fit when the main concern is speech clarity, a language delay without major behavior barriers, or choosing an AAC device.
- ABA first, or both together, may fit when behaviors such as aggression, self-injury, running off or long meltdowns make it hard for your child to take part in any therapy, school or family routine.
- Both together is common when communication and behavior are tied together, for example a child who hits because they cannot yet ask for what they need.
A useful question to ask each provider: What will you work on in the first three months, and how will we know it is helping? Clear, measurable answers from both sides make it easier to decide.
A short decision checklist
- Has your child had a speech-language evaluation? If not, ask the pediatrician for a referral or ask the school about an evaluation.
- Is there a behavior that is unsafe or that stops learning in most settings? If yes, ask about a BCBA assessment.
- Does your child need an AAC system? An SLP should lead the choice; the BCBA can help your child practice using it all day.
- What does your plan cover, and are there visit limits for speech? Call member services (see below).
- Can your family realistically attend both? A plan you can keep up with is worth more than a schedule that collapses in a month.
Can ABA replace speech therapy, or the other way around?
Not usually. ABA can build functional communication, and a good BCBA will target it. But an RBT is not trained to diagnose or treat speech sound disorders, plan therapy for apraxia or fit an AAC device. Likewise, a weekly speech session cannot provide the hours of practice across settings, or the behavior support, that an ABA program offers.
The BACB Ethics Code expects behavior analysts to "collaborate with colleagues from their own and other professions in the best interest of clients" (standard 2.10) and to deliver nonbehavioral services only if they hold the training and credentials to do so (standard 2.01). In plain terms: a BCBA should work alongside your child's SLP, not stand in for one.
How does Florida insurance handle ABA and speech therapy together?
Florida's autism insurance law, the Steven A. Geller Autism Coverage Act (s. 627.6686), requires covered plans to cover treatment of autism and Down syndrome "through speech therapy, occupational therapy, physical therapy, and applied behavior analysis." It applies to fully insured large-group plans, group HMOs and the state employee plan, for eligible children. It does not reach self-funded employer plans, small-employer plans or individual plans. The guide to the Geller Act explains who is covered.
Two practical rules matter when your child gets both therapies:
- Same-time billing. Some payer policies will not pay for ABA delivered at the same time as another therapy. Evernorth (Cigna) Coverage Policy EN0499, effective 5/15/2026, lists as not covered ABA "delivered to the same individual, at the same time as any other treatment modality (e.g., ABA and speech therapy, or ABA and occupational therapy)." That usually means sessions need to be scheduled back to back rather than overlapping, even if an RBT sits in on a speech session to learn the strategies. Ask your plan how it treats co-treatment.
- Visit limits and authorizations. Speech therapy and ABA are often authorized separately, with their own rules. Some plans set yearly visit limits for therapies; some require prior authorization for ABA but not for a speech evaluation. Your plan documents decide.
When you call member services, ask: Is speech therapy covered for my child's diagnosis? Is there a visit limit? Is prior authorization required for ABA and for speech? Can both happen on the same day? Ask for the answers in writing.
How do I get ABA and speech working toward the same goals?
- Sign releases so the BCBA and SLP can talk and share reports.
- Share the plans. Give each provider a copy of the other's goals. Look for one or two communication goals both can support.
- Agree on the communication system. If your child uses AAC, everyone should use the same device, vocabulary and prompts.
- Bring both to the IEP table if your child is in school. Florida's IEP rule lets parents invite people with knowledge or special expertise about the child, which can include a private BCBA or SLP.
- Watch for overload. Two therapies plus school is a lot for a young child. Ask both providers to account for rest, play and family time in their schedules.

Does Hope Center offer speech therapy?
Not yet. Hope Center for Behavior Change is adding in-house speech therapy, now in credentialing, with services planned to start in January 2027. When it opens, speech and ABA goals will be planned together by one team. Until then, Hope Center provides ABA (center, home, school, daycare and community), parent training, assessments and mental health therapy, and coordinates with your child's outside speech therapist. Hope Center does not offer occupational therapy.
ABA at Hope Center has no waitlist. You can read more about the upcoming speech therapy service, or request a free consultation and benefits check, or call 561-337-8865 to talk through where your child might start.
