The process starts with a comprehensive assessment lasting three to five hours, often spread across two to three visits. The BCBA observes the child, conducts standardized skill assessments (VB-MAPP, ABLLS-R, or AFLS), and interviews parents about priorities and concerns. They then create a treatment plan with specific, measurable goals. Therapy sessions range from 10 to 40 hours per week depending on the child's needs and age, delivered by an RBT under the BCBA's supervision. The BCBA meets with parents regularly to review data, teach strategies for home, and update goals. Progress is measured through ongoing data collection at every session.
A BCBA is typically recommended for children diagnosed with autism spectrum disorder, particularly between ages two and six when early intervention has the greatest impact. ABA therapy also benefits older children, teens, and adults with autism or other developmental disabilities who need support with communication, social skills, self-regulation, or daily living skills. Parents may seek ABA after noticing delays in speech, difficulty with transitions, repetitive behaviors, or challenges with peer interaction. BCBAs also help with specific behavioral concerns like aggression, self-injury, elopement (running away), and feeding difficulties.
BCBA assessment: $1,200-3,000 · ABA session (RBT-delivered): $35-75/hour · BCBA supervision: $100-200/hour · Typical monthly cost at 20 hrs/week: $3,000-6,000
ABA therapy is covered by most insurance plans under state autism mandates. Coverage requires an autism diagnosis and a treatment plan from the BCBA. Prior authorization and periodic reauthorization (every 3 to 6 months) are standard. Some plans have hour caps (e.g., 25 hours per week), age limits, or dollar caps, though many states have eliminated these. Medicaid covers ABA in all states under the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit for children. If your plan denies or limits hours, ask the BCBA to write a letter of medical necessity with supporting data.
