Ask an owner what drives their margin and you’ll usually hear about rates and payers. Ask what keeps them up at night and you’ll hear about hiring and keeping BCBAs. These are often the same problem, and caseload design sits right in the middle of it.
What we mean by caseload design
Caseload design is the structure behind your clinical team: how many clients each BCBA carries, how many RBT hours each BCBA supervises, how much of their week is spent on billable work versus admin and travel, and how those caseloads are spread across your geography.
Clinical needs and payer supervision requirements come first. Those are your clinical team’s call, and they set the boundaries. Inside those boundaries, though, there’s a lot of room for design, and most agencies never use it on purpose. Caseloads just happen, one new client at a time.
Why it drives margin
BCBA time is one of the most valuable resources in your agency. When a BCBA carries too few hours, their cost is spread across too little revenue and the margin on every hour they supervise gets thinner. When caseloads are uneven, some clinicians are underused while others are stretched, and the agency pays for both.
The number to watch isn’t just clients per BCBA. Two BCBAs with the same number of clients can have very different workloads depending on the hours each client receives. Count caseloads in hours, and look at RBT hours supervised per BCBA alongside it.
Why it drives retention
The opposite failure is just as expensive. Overloaded BCBAs burn out. When one leaves, their whole caseload freezes: clients wait, RBTs lose supervision, hours go undelivered, and you pay to recruit and train a replacement. One departure can undo months of growth.
Good caseload design gives clinicians a workload they can sustain and a reason to stay. It’s not a perk. It protects revenue.
The levers you can actually pull
- Set a target range, on purpose. Decide what a full caseload looks like at your agency, in hours, and staff to it rather than to whoever is available.
- Cluster by geography. Drive time is unpaid time. Grouping clients and RBTs by area gives BCBAs back hours every week.
- Watch the non-billable load. Admin, scheduling and paperwork that land on BCBAs take time away from billable work. Moving it to the right support role is often the cheapest margin gain available.
- Balance across the team. Review caseloads monthly, so new clients go where there’s room, not to whoever answered the phone.
- Build a path. Senior or lead BCBA roles give strong clinicians somewhere to grow, which makes them far more likely to stay.
What to track
A healthy agency can answer a few questions at any time: what each BCBA’s caseload is in hours, how many RBT hours each one supervises, how their week splits between billable and non-billable work, and how many caseloads are open or uncovered. If those answers take a week to pull together, they’re not being managed.
That’s where we help. We put caseload numbers next to your margin numbers in one simple view, so you can see where structure is costing you money or people, and we work through the changes with you and your clinical leaders.
