Just diagnosed? Four things to decide before you start ABA therapy

New to ABA? ABA therapy, short for applied behavior analysis, is an evidence-based therapy for children with autism spectrum disorder (ASD). The goal is to help children communicate, play and get through daily routines with less struggle. Board certified behavior analysts (BCBAs) assess each child against developmental milestones and write a personalized therapy plan, and registered behavior technicians (RBTs) work on the goals in it: communication, social skills and social interaction, daily living skills and behavior. Good providers individualize that plan and tailor it to your family, so it should look different from one child, and one Littleton provider, to the next.

Home, center or a mix

In-home ABA teaches skills where your child uses them: meals, bath time, bedtime. A center offers peers, a practice classroom and a set schedule. Some providers do both.

Does the provider take your child's age

On this list, eight of nine providers say they take children under 3, and some centers stop at age 5, 8 or 10. If your child is a toddler, ask this first, because it rules providers out fastest.

How you will pay

Health First Colorado (Colorado Medicaid) covers behavioral therapy for eligible children when it is medically necessary, and an autism diagnosis is not required. With private insurance, ask the provider to check your exact plan before the first session. In Littleton, it is managed regionally by Colorado Access.

How soon you can start

Waits change month to month. Ask two questions: is there a waitlist for the assessment, and is a therapist free at the hours your child needs in your ZIP code.

ABA therapy for children with autism in Littleton: the providers, one by one

Each write-up covers what ABA therapy for children looks like at that provider: setting, ages, parent involvement, insurance and availability, using only what the provider publishes. Budding Futures comes first because this is our site and we can describe our own program in the most detail; the rest follow in no particular order.

1Budding Futures ABA

Fits families who want therapy at home, starting as young as 18 months

Budding Futures brings ABA therapy to your home. There is no clinic to drive to. A registered behavior technician comes to your house, and a Board Certified Behavior Analyst (BCBA) plans and supervises the work. We work with families in homes across Littleton, Columbine and Ken Caryl. Here is our page on in-home ABA therapy in Littleton.

What therapy looks like for a young child

Our youngest clients are 18 months old, and we stay with families through age 18. With toddlers, most of the work is play. A therapist might build first words around bubbles, a snack or a favorite song, because that is where a two-year-old is paying attention. Therapy is built on play and assent. Breaks are part of the plan, and punishment-based techniques are not.

Parent coaching and the same therapist

Parent coaching is part of every plan, usually 10 to 20% of the hours. You learn the same prompts and routines the therapist uses, so progress keeps going after the session ends. The same technician works with your child session after session.

Who runs your child's plan

Clinical oversight is closer than the minimum rules require. A BCBA supervises about 20% of therapy hours, four times the BACB floor, under our Clinical Director, Rachel Blackburn, BCBA. Assessments use VB-MAPP and ABLLS-R, and session data goes into CentralReach the same day.

School, insurance and start times

For school-age kids we also work with schools. We reach out, ask for access and share goals with teachers when you say yes. Some districts let an outside therapist in and some do not. More on how that works: school-based ABA in Littleton.

Budding Futures accepts Health First Colorado (Medicaid) as Provider Types 83 and 84, plus Aetna, Cigna, UnitedHealthcare, Anthem BCBS and TRICARE. We check your benefits for free before therapy starts. We do not balance-bill families, and most Health First Colorado families pay $0 out of pocket. We have no waitlist. Intake usually takes a couple of weeks, and therapy starts once the insurance approval is back.

Autism therapy and care for children under 3 in Littleton

Start Early Intervention Colorado at the same time

Early Intervention Colorado is the state's free program for children under 3, with no income limit. For the Arapahoe and Douglas County parts of Littleton, the local agency is Developmental Pathways (303-360-6600). Downtown Littleton and most of its ZIP codes are Arapahoe County, and Developmental Pathways also covers the Douglas County edge. A Jefferson County address routes to DDRC instead, so a Ken Caryl family and a downtown family may call different agencies. Anyone can refer, including you, through the state's online referral form.

Early intervention and ABA can run side by side. The state coordinator writes the family service plan, the ABA provider writes the behavior plan, and with your permission the two share goals. See how that works in practice: early intervention ABA in Littleton.

At age 3, the school side takes over. Littleton Public Schools runs Child Find for ages 3 to 5, with special education support distributed school by school rather than in one central autism program.

If your child has Health First Colorado, the state's behavioral therapy benefit does not require an autism diagnosis when therapy is medically necessary. Littleton is in Arapahoe County, with edges in Jefferson and Douglas counties, where Medicaid is managed regionally by Colorado Access.

How to get started with ABA therapy in Littleton

Most families in Littleton go through the same five steps, whichever provider they pick. Knowing them ahead of time makes the first calls shorter and can help your child start sooner.

  1. Get the referral paperwork readyKeep the diagnostic report if you have one. Health First Colorado does not require an autism diagnosis for behavioral therapy when it is medically necessary, but a private plan may ask for one, so check yours.
  2. Ask for a benefits checkCall two or three providers from this list. Each one should check your coverage for free and tell you what you will owe before anything is scheduled.
  3. The BCBA assessmentA BCBA meets your child, watches play and routines, and often uses a skills assessment such as VB-MAPP or ABLLS-R. You talk through your goals for the family.
  4. Prior authorizationThe provider sends a treatment plan to your insurer. With Health First Colorado, a Prior Authorization Request goes to the state's review vendor, and you get a letter with the decision and your appeal rights.
  5. First sessionsThe first weeks are mostly getting to know each other. Expect play, short sessions that grow longer, and your first parent coaching.

Questions to ask ABA therapy providers on the first call

Every child with autism is different, so the right answers depend on yours. Write them down for every provider you call; side by side, the differences get obvious fast.

  • Do you work with children my child's age, and what is the youngest age you take?
  • Is there a waitlist for the assessment, and for a therapist at the hours we need?
  • Will therapy happen at home, at your center or both?
  • Who is the BCBA or lead clinician on my child's case, and how often will they see my child?
  • How is parent and caregiver training scheduled, and is it required?
  • Will my child keep the same technician from week to week?
  • Can you check my Health First Colorado or private plan for free before we start?
  • How will you show me my child's progress?
  • What does a session look like for a two- or three-year-old?
  • Can my child take breaks or say no during a session?
