ABA Therapy Process: From Referral to the First Session (Step-by-Step Guide)

Key Points:

• The ABA therapy process starts with a referral and intake call, followed by record collection, insurance verification, completion of a BCBA assessment, and submission of a treatment plan. 
• First sessions focus on building rapport, setting routines, and beginning simple goals to help the child and family adjust smoothly.
• Most delays stem from insurance or missing documents, so staying proactive can shorten wait times.

A referral gets made, the phone rings, and then the waiting starts. The hardest part is that families often do not know what is happening behind the scenes or what to do next to keep things moving.

The timeline below breaks down the steps families typically go through, what each step is for, and what you can do in each stage of an ABA therapy process to avoid delays and start services with fewer surprises.

Referral Start: What Kicks Off the ABA Therapy Process?

A referral can come from a pediatrician, a psychologist, a neurologist, a school team, or a parent who calls a provider directly. CDC estimates that about 1 in 31 8-year-old children were identified with autism in 2022. This means that many clinics and specialty services are busy and may triage referrals based on documentation and urgency. 

Diagnosis versus no diagnosis is the first decision point. Some families call because they already have a diagnostic report. Others call because autism is suspected, and they want support while waiting for diagnostic appointments. 

Either way, the first practical goal is the same: open a file with a provider and confirm what documentation your plan needs to start.

A simple referral prep list can keep this stage from stalling.

• Caller details: Share the legal name, date of birth, and the best phone and email to reach you.
• Insurance basics: Provide the subscriber name, member ID, and plan type.
• Current concerns: Describe what is happening day to day in plain terms, including safety concerns, if any.
• School context: Share whether there is an IEP, 504 plan, or a recent school evaluation.
• Clinic history: List current therapies and any recent assessments, even if they were not autism-specific.

Provider Match And Intake Call: What Opens the File Quickly?

Waitlists are common, so it helps to treat this step as a branching path rather than a dead end. A large CMS survey of autism evaluation centers found that nearly 61.26% reported waits longer than 4 months, and 15.32% reported waits over one year or had waitlists so impacted that they paused new referrals. 

A helpful intake call usually includes screening, expectations, and next steps. Before you get to questions, it helps to know what the provider is trying to confirm:

• Whether services are clinically appropriate for the concerns you described
• Whether your plan and location can be supported
• Whether records exist that can speed up authorization and assessment planning

A question list keeps the call focused without turning it into an interview.

• Availability: Ask what the earliest assessment appointment looks like and what could change that timeline.
• Waitlist options: Ask if there is a cancellation list and what counts as “short notice.”
• Setting fit: Ask first whether home-based vs center-based ABA therapy options are available, and why.
• Team roles: Ask who leads the assessment and who provides direct sessions.
• Communication: Ask how updates are shared, including phone, email, or a parent portal.
• Caregiver role: Ask about expected participation during early sessions.
• Records: Ask for a list of documents that can be emailed or uploaded right away.
• School coordination: Ask if the provider can coordinate with the school team or other school-based ABA therapy supports if needed.

Records Checklist: What To Gather Before Scheduling Gets Easier

Records speed things up by reducing repeated questions and helping the clinical team plan an efficient autism assessment. They also help insurance teams confirm benefits and medical necessity without multiple follow-ups.

Most providers ask for a short list, plus optional items that help if you have them.

• Insurance cards: Include the front and back, plus subscriber information if different from the client.
• Diagnostic reports: Share autism-related reports if available, plus any developmental or psychological evaluations.
• Medical notes: Share relevant notes from pediatricians or specialists if you have recent copies.
• School documents: Include an IEP or 504 plan, recent evaluation summaries, and any behavior support plan.
• Current therapy notes: Include summaries of speech, OT, or counseling, if available.
• Behavior notes: Share a short home log of the top concerns, including time of day and triggers.
• Safety concerns: Share any relevant information about elopement, self-injury, aggression, or severe property destruction.

A quick way to organize a home log is to keep it simple for five to seven days.

• What happened: Describe the behavior in everyday terms.
• What came before: Note what was asked, denied, changed, or introduced.
• What happened after: Note what the child gained or avoided right after.

Insurance Verification And Prior Authorization: Why This Step Can Add Time

Insurance verification is often the first “hidden” step. Families may not see it, but it often determines what happens next with insurance coverage for ABA therapy, including whether an assessment can be scheduled immediately or needs approval first.

Prior authorization is also common in healthcare, and it can create delays even when services are covered. In the AMA’s 2024 physician survey, 93% reported that prior authorization causes delays in patient care. 

The most common “snags” are usually fixable, but they often cost time because they require a new submission or an extra phone call.

• Missing plan details: A wrong member ID or an outdated plan can stop verification.
• Out-of-network limits: Some plans cover out-of-network care differently or require extra steps.
• Prescription rules: Some plans need a referral or prescription on file before approval.
• Medical necessity language: Some plans want specific wording tied to daily functioning and safety.
• Benefit limits: Some plans set hour caps or require regular re-approvals.

A simple way to reduce rework is to ask for clarity on three things during the intake stage.

• Requirements: Ask whether authorization is needed before the assessment or only before ongoing sessions.
• Timeline: Ask how long approvals typically take for your plan type.
• Next steps if denied: Ask what documents or edits are typically needed for resubmission.

BCBA Assessment: What Happens During an Autism Therapy Evaluation?

Assessment visits are when the clinical plan takes shape. Families often imagine a “test,” but many assessment visits look more like observation, structured play, and caregiver questions, especially for younger children.

A typical assessment visit often includes:

• Observation during play, routines, or structured tasks
• Questions about daily living skills, communication, and learning readiness
• A review of which behaviors are happening, when, and why they might be happening
• A discussion of family goals that are realistic for the next three to six months

Caregiver interviews usually feel easier when families arrive with examples.

• Daily routines: Share what mornings, meals, and bedtime look like on typical days.
• Communication: Share how your child asks for help, a break, or preferred items.
• Learning patterns: Share what helps your child engage, and what shuts things down quickly.
• Safety: Share the situations where you feel you need the most support right now.
• Strengths: Share what your child enjoys and what already works well.

Treatment Plan Submission And Scheduling: How The Calendar Finally Gets Set

After the assessment, the clinician typically drafts a treatment plan that ties goals to the needs you described and what was observed. Then it is submitted to insurance if authorization is required, or moved into scheduling if approval is already in place.

Starting services also looks different depending on the setting.

• In-home scheduling: Consider when the home is calm enough for learning and when caregivers can participate.
• Center-based scheduling: Consider travel time, drop-off routines, and how your child handles center-based ABA therapy in new spaces.
• Hybrid schedules: Consider whether a mix helps, such as center sessions for learning and home sessions for routines.

Starting ABA therapy is often smoother when families plan for simple, repeatable routines rather than trying to “perfect” the first week. A good first-week goal is consistency, not intensity.

A short prep checklist can help you feel ready without over-planning.

• Space: Choose one area for early sessions that feels safe and low-distraction.
• Reinforcers: Make a small list of preferred items and activities, including snacks if appropriate.
• House rules: Share any boundaries, like off-limits rooms or pet routines.
• Communication: Decide how session notes will be shared and who will read them daily.

First Session And First Week: What Happens First

First-day nerves are normal. Families often worry that the first visit will be rigid or full of demands. In reality, the first visit usually sets the tone and builds the relationship that makes skill-building possible later.

What To Expect From ABA In Session 1

The first ABA session often looks like rapport building with a plan. Pairing and engagement come first, so the therapist can become a safe, positive part of the routine.

• Rapport building: The therapist follows the child’s interests and joins play in a low-pressure way.
• Caregiver interview: The caregiver shares routines, stress points, and what a better day would look like.
• Environment scan: The therapist notes where challenges show up, like transitions, meals, or homework time.
• First targets: The therapist may try a simple skill, like responding to name or requesting help, if the child is ready.

ABA Therapy Process In The First Week: What Changes And What Stays The Same

The first week usually sets habits that carry into the rest of the ABA therapy timeline. The goal is a steady routine that helps the child and family adjust without feeling exhausted.

• Session structure: The team builds a predictable start and end routine.
• Early goals: The team picks a few goals that feel meaningful right away, such as helping requests or smoother transitions.
• Data basics: The team tracks simple measures to see what is improving and what needs adjustment.
• Home practice: The caregiver gets a small plan that fits real life, not a long checklist.

Frequently Asked Questions

Can parts of onboarding happen through telehealth?

Parts of ABA onboarding can happen through telehealth, including caregiver interviews, planning, and some training. A hybrid model is common, with remote sessions for preparation and in-person visits for observation and skill work. Telehealth use must follow clinical guidelines for privacy, safety, and goal selection.

Do parents have a right to get copies of records needed for intake?

Yes, parents have the right to get copies of records needed for intake. Under HIPAA, they can request their child's health records, including evaluations and visit notes, unless limited by state laws or special circumstances. Asking for “the most recent evaluation reports and visit notes” is a practical approach.

What changes when the client is 18 and the family wants to stay involved?

When a client turns 18, providers need written authorization to share information with family members, even if parents remain involved. Legal adulthood changes default access rights. Families can plan ahead by completing release forms, especially if services continue into adulthood. Ask the provider what forms are required.
