Why RBTs Quit in the First 90 Days (And How to Fix It)

If your agency is losing new hires before they hit their 90-day mark, you're not alone — and it's rarely about pay. First-quarter turnover among RBTs is one of the most expensive, most fixable problems in ABA staffing, because most of the reasons technicians leave early trace back to onboarding and support gaps rather than the job itself. Here's what's actually driving it, and what agencies that retain well are doing differently.

Reason 1: They Felt Unprepared on Day One

A technician who completes 40 hours of training and then gets handed a full caseload with minimal shadowing is set up to feel overwhelmed fast. The agencies with the strongest 90-day retention build in a structured ramp — shadowing experienced RBTs for the first several sessions, starting with a lighter caseload, and scheduling a check-in at the two-week mark specifically to ask what's going well and what isn't. This costs a little coordination time and saves a lot of turnover.

Reason 2: Supervision Felt Distant or Inconsistent

New RBTs need frequent, accessible contact with their supervising BCBA in the first month — not just the BACB-required supervision minimums, but real availability when something goes wrong mid-session. When technicians feel like they're troubleshooting alone with a difficult behavior and can't reach anyone until the next scheduled supervision meeting, confidence erodes fast. Agencies that assign a go-to point of contact for the first 30 days, separate from the formal supervision schedule, see technicians stick around longer.

Reason 3: The Schedule Didn't Match What Was Promised

Nothing burns trust faster than a technician being told they'd get 30 hours a week and then getting 18 because of client cancellations, especially when they've already given notice at a previous job. Agencies with better retention are upfront during hiring about realistic hour ranges, have a plan for filling gaps when a family cancels (float caseloads, make-up sessions, brief training time), and communicate schedule changes with real notice rather than a same-day text.

Reason 4: No One Checked In Before It Became a Resignation

Exit interviews consistently surface the same theme: the technician had been struggling for weeks, but no one asked until they'd already decided to leave. A short, low-pressure check-in at 30, 60, and 90 days — not a performance review, just a real conversation about how things are going — catches problems while they're still solvable. Several agencies have started assigning this specifically to a peer mentor rather than a supervisor, since new hires are often more candid with someone who isn't evaluating them.

Reason 5: There Was No Visible Next Step

Even technicians who enjoy the day-to-day work will start job-hunting if they can't picture where the role leads. Retention improves when agencies talk about the RBT-to-BCaBA-to-BCBA path during onboarding, not just during an annual review — and even better when there's a concrete internal example, like a current BCBA who started at the agency as an RBT.

The Bottom Line

None of these fixes require a bigger budget — they require treating the first 90 days as its own distinct phase with its own plan, rather than an extension of the interview process. Agencies that do this consistently spend less on re-recruiting and more time actually growing their caseload capacity.
