ABA
In-home ABA session scheduling: the authorized hours, the after-school window, and the drive between.
Two or three clients a day, each for hours, every family wanting the same evening slot, and a cancellation that costs a third of the day. How to build a week that still delivers the authorized hours.
An in-home ABA day is a short list of long addresses. A registered behavior technician might see two or three clients, each for two to four hours, with a drive in between that is often the only unpaid part of the day. A BCBA's day is the same list spread wider: supervision sessions, parent training, assessments, and a drive between each of them. Scheduling that day looks simpler than a nurse's eight visits, and it is harder in three ways: the hours are authorized rather than ordered, the families' time is concentrated into one evening window, and the cancellation rate is higher than in almost any other kind of home visit.
This is a practical guide to in-home ABA session scheduling for RBTs, BCBAs, BCaBAs and the office staff who build the week: what shapes it, where it breaks, and a way of building it that still delivers the authorized hours when a Tuesday session cancels at 2:40.
What shapes an in-home ABA week
- Hours are authorized, not ordered. A payer approves a number of direct hours a week, commonly somewhere between ten and thirty for a comprehensive program, plus a smaller number of supervision and parent-training hours. The week is measured against that number. Hours not delivered are usually not paid, and a program that repeatedly under-delivers is the one a reviewer asks about at reauthorization. Your payer's rules are the ones that apply.
- Sessions are long. Two to four hours is typical, so a technician's day holds two or three clients, not eight. One cancellation is a third of the day, not an eighth of it.
- The after-school window. School-age clients are available from roughly three to seven in the evening. Every family wants the same four hours, and a technician can fill at most one or two of those slots. Clients under five, who are often home all day, are what fill the mornings.
- Supervision has its own clock. The BACB requires an RBT to be supervised for a percentage of the hours they deliver each month, with part of it face to face, and most payers set their own expectations for BCBA oversight. Check the current BACB requirements and your payer's; whatever the figures, a supervision session has to land inside a direct session, so two people's drives have to meet at one house.
- Consistency matters clinically. A client paired with one technician for months loses something every time a stranger arrives. Coverage by whoever is free is a last resort, not a scheduling tool.
Where the ABA week usually breaks
| What happens | Why it happens |
|---|---|
| The week lands under the authorization. | Two family cancellations and no open slot to make them up. Authorized hours expire with the week; the make-up had nowhere to go. |
| A technician drives across town between two sessions. | Each client was assigned by availability alone, never by where the technician's other client lives. |
| Supervision is late. | It rode along with a routine session that then cancelled, and the BCBA's week had no second slot near that address. |
| The evening is overbooked and the morning is empty. | Every school-age client was promised four to six, and the under-fives were never asked whether mornings would suit. |
| A technician quits. | Four hours of sessions, two hours of unpaid driving, and a cancellation that cost a third of the day's pay. Scheduling is part of turnover, not separate from it. |
A way to build the ABA week
Start from each client's authorized hours
List every client with the direct hours, supervision hours and parent training authorized for the week, and the date the authorization ends. That is the target. A day count on its own hides the week that is two hours short; our piece on visits per day makes the same argument for nursing.
Place the fixed sessions first
Supervision that is due this month, assessments with a deadline, and families whose window is genuinely fixed (a school pickup, a parent's shift) go on the calendar before anything else. The note on time windows covers which windows are facts and which are preferences worth asking about.
Give each technician a territory, then thread the day
A technician whose morning client and afternoon client are ten minutes apart delivers the same hours with an hour less driving than one whose clients are forty minutes apart. Assign new clients to the technician whose existing clients are nearest, not just whoever has the hours free. The step-by-step version is in how to plan a home health route by hand; the method is the same with three stops as with eight.
Pair a morning client with an evening client
A technician with one under-five in the morning and one school-age client after school delivers six hours with one drive and a gap. Two after-school clients cannot both have four o'clock, so the evening window is the scarce resource and the morning is what pays for it.
Hold a make-up slot inside the week
Leave one slot late in the week unbooked for each technician where you can, and ask each family at intake which day would work for a make-up. A cancelled Tuesday session that becomes a Friday session keeps the week at its authorized hours. What to have ready before the day starts is in cancellations in home health.
Count the drive as part of the day
A technician's day is sessions plus driving, and the driving is usually the part nobody is paid for. Federal wage law generally treats travel between worksites during the working day as hours worked, and some states go further; check the Department of Labor and your state, since this is not legal advice. The Windshield Tax calculator puts a rough figure on what the drive costs the person doing it.
Cancellations, and the make-up rules families agree to
In-home ABA has a higher cancellation rate than most home visiting, because the client is a child and the session depends on the whole household: an illness, a sibling's recital, a parent who is not home yet. Most providers set a cancellation policy at intake (notice required, how many late cancellations before a conversation about the plan) and the useful ones pair it with a make-up offer, so the policy is about keeping the hours rather than punishing the family. A technician who hears about a cancellation at 2:40 for a three o'clock session cannot refill it; one who hears the night before often can. The office's job is to make the notice flow early, which is a phone and a habit more than a system.
The BCBA's week is the harder one
A technician's week is three addresses a day. A BCBA's is a dozen technicians' weeks overlaid: supervision that has to coincide with a direct session, parent training the family can only attend in the evening, assessments that run two hours, and a caseload spread over the whole territory. The same rules apply with less slack: cluster the supervision visits by area and by day, do parent training by telehealth where the payer allows it (check your payer) so the evening drive is spent on sessions that need to be in the home, and keep assessments off days with evening supervision.
If you are comparing tools, our honest comparison of home health scheduling apps separates the ones built for an office from the ones built for the person driving. The wider case is in what home health scheduling software has to do.
Questions people actually ask
How many clients does an in-home RBT see a day?
Usually two or three. Sessions commonly run two to four hours, so a full-time technician's day is six to eight direct hours across two or three homes, plus the driving between them. Part-time technicians who only work the after-school window often see one client a day.
How many hours of ABA are authorized a week?
It depends on the payer and the assessment. Focused programs are often authorized at around ten to fifteen hours a week and comprehensive ones at twenty-five to forty, with supervision and parent training approved separately. The authorization letter is the number that counts; check it rather than a rule of thumb.
How much supervision does an RBT need?
The BACB requires an RBT to be supervised for a minimum percentage of the hours they provide each month, with some of it in person and observing a session with a client. Payers add their own expectations. Check the current BACB RBT requirements and your payer's policy, since both have changed over time.
Do ABA technicians get paid for drive time between clients?
Often, and sometimes not. Federal wage law generally counts travel between worksites during the working day as hours worked, the commute to the first client and home from the last is usually not, and several states have stricter rules. Mileage is a separate question from time. Check the Department of Labor and your state; this is not legal advice.
What is a reasonable cancellation rate for in-home ABA?
Higher than for most home visits, because sessions depend on a child and a household. Many providers see a meaningful share of scheduled sessions cancelled and set a cancellation policy at intake with make-up sessions offered. What matters for the week is whether a cancelled session can be made up inside the authorization period.
Can parent training be done by telehealth?
Many payers allow parent training and some supervision by telehealth, and many do not or limit it. It saves an evening drive when it is allowed. Check your payer's current telehealth policy before scheduling it that way.
