ABA has a revenue mechanic no other therapy business shares: insurers pre-approve a set number of treatment hours per child, and the clinic earns only the hours it actually staffs and delivers. Winning the authorization takes hard clinical and administrative work. Which makes the industry’s quietest number so uncomfortable: the average practice delivers just 42.6% of the service hours payers have already authorized, and utilization of authorized family-service hours sits at 26% (CentralReach 2025 market report).
More than half of the revenue the average clinic already won is expiring unbilled. This article is about where it goes and how to get it back.
Frequently asked questions
What is a utilization rate?
Billed hours divided by authorized hours. It is the cleanest single measure of whether your staffing matches the caseload you already won. The industry average is 42.6%; well-run clinics track it weekly.
Why is utilization so low across the industry?
The report names staffing first: open BCBA seats and technician turnover (ABA organizations average 77-103% annual staff churn), then scheduling friction and low family engagement. Demand is not the constraint — roughly 75% of families report waiting for ABA services, for an average of nearly six months.
What does an unstaffed BCBA seat actually cost?
Every hour under that seat’s caseload that goes undelivered is authorized revenue expiring, plus families drifting toward the waitlists of competitors, plus technicians with no supervisor to bill under. The seat does not just miss its own revenue; it stalls the billable work beneath it.
The four utilization levers
| Lever | What it looks like when broken | The fix that works |
|---|---|---|
| BCBA seats | Open seats; caseloads parked or split | Fill fast and for fit; a stable BCBA steadies everything beneath |
| Technician stability | 77-103% annual churn; constant re-pairing | Training depth, sane schedules, supervision quality |
| Scheduling | Cancellations unfilled; gaps unmanaged | Active same-week backfill and cancellation response |
| Family engagement | 26% utilization of family services | Caregiver training investment, linked to up to 30% lower client churn |
The weekly ratio worth taping to the wall
Run one check this week: last month’s billed hours divided by authorized hours, per site. Above 70% is strong. Between 60% and 70% is workable with scheduling discipline. Below 60% is almost always a staffing problem wearing a scheduling costume, and the first question to ask is which BCBA seats are empty or overloaded.
Clinics usually attack utilization with scheduling software first because it is the cheapest lever to pull. But software cannot staff an hour. If the ratio is low and a seat is open, the seat is the lever — and filling it in weeks instead of months is exactly what a specialist behavioral-health desk exists to do.
More frequently asked questions
How fast can a BCBA seat realistically fill?
Generalist channels run months in a market with 1.6 job postings per existing BCBA. A behavioral-health-only desk with a pre-screened bench delivers a shortlist within one business day and fills in about 21 days on average.
Does telehealth help utilization?
It widens the supervision radius and softens geographic gaps, but authorized direct hours are still delivered by staffed humans. Telehealth stretches a roster; it does not replace one.
Which metric should leadership review alongside utilization?
Client churn. Families rarely leave over clinical quality; they leave when the faces keep changing. Providers that invested in caregiver engagement saw churn fall by as much as 30%, and the same staffing stability that lifts utilization is what keeps the faces consistent.
