Every Florida Medicaid ABA plan has to be built on two standardized instruments: the Vineland Adaptive Behavior Scales, Third Edition (Vineland-3) and the Behavior Assessment System for Children, Third Edition (BASC-3). Parents often hear the names in the authorization letter and nothing else. Here is what they measure and why they matter for your child's hours.
Vineland-3: what your child does day to day
The Vineland-3 measures adaptive behavior, the practical skills of daily life, in four domains: communication (understanding, speaking, reading and writing at an age-appropriate level), daily living skills (eating, dressing, hygiene, chores, safety), socialization (play, relationships, coping) and motor skills for younger children.
The BCBA administers it as a structured interview with you, usually 45 to 90 minutes, asking whether your child does specific things "usually," "sometimes" or "never." There are no right answers; the point is an honest picture. If your child does something only with prompting, say so; that is exactly the kind of detail that becomes a goal.
Scores are reported as standard scores with a mean of 100. A composite in the 70s or below is common for children who need intensive ABA and is one of the numbers reviewers look at when approving hours.
BASC-3: behavior at home and in the community
The BASC-3 Parent Rating Scales are a questionnaire you complete (about 20 minutes, available in Spanish) covering behaviors like hyperactivity, aggression, anxiety, withdrawal and attention, along with adaptive skills such as social skills and functional communication. Florida Medicaid requires the parent form for ages 2 to 18. Where your child is in school, the teacher form can add useful context but is not required.
The functional behavior assessment
Alongside the two instruments, the BCBA observes your child, usually across two or three visits at home or school, to understand why challenging behaviors happen: what tends to come before them, and what they get your child (attention, escape from a demand, access to something, sensory input). That analysis is what makes an ABA plan specific rather than generic.
How it becomes a treatment plan
The BCBA combines the scores, the observations and your priorities into a plan with measurable goals in each domain, recommended hours per week for direct therapy (CPT 97153), supervision and protocol modification (97155) and caregiver training (97156), and the settings where therapy happens. The plan is submitted to your health plan for authorization, typically in six-month blocks.
Every six months the instruments are re-scored or re-administered as the plan requires, so progress is documented in the same units the plan approved against. Reassessment is also where hours are most often cut when documentation is weak; it is the part of the process we are most careful about.
How to prepare
Bring the CDE report and any school evaluations. Think ahead about what a good year would look like for your child and your family; those priorities belong in the plan. Have your child's schedule handy so the BCBA can recommend realistic hours. And ask questions; a plan you understand is a plan you can help carry out at home.
Assessments are billed under CPT 97151 and rarely require prior approval. Call 786-612-1151 to schedule one in English or Spanish.
