There is a pattern in when families call us frustrated. It is rarely week two. It is usually somewhere around month four or five, once the initial relief of having services has worn off and the ordinary friction has set in.
That friction is not a sign that something has gone wrong with your family. It is close to universal, and most of it is predictable enough to plan for. The numbers back that up: in one study of nearly 300 insured children referred for ABA, roughly a quarter never started at all, and among those who did, about a third stopped within twelve months. Those are not families who stopped caring. They are families who hit something and did not know it was normal or fixable.
Six challenges, roughly in the order families hit them:
- Starting takes longer than anyone tells you, and the delay itself affects whether therapy sticks.
- The first few weeks often look worse before they look better.
- Losing a therapist your child had bonded with is common and disruptive, but the damage is limited by how the provider handles it.
- The hours on your authorization letter and the hours actually delivered are two different numbers.
- Progress plateaus, usually for a reason your data can identify.
- Skills appear in session and then fail to show up at home, which is a design problem rather than a mystery.
Quick Answer: What Are the Most Common Problems in ABA Therapy?
The recurring ones are slow starts, difficult early weeks, staff turnover, a gap between authorized and delivered hours, progress plateaus, and skills that do not carry over into daily life. Almost all of them are addressable, and the fix usually starts the same way: bring the specific problem to your BCBA, ask what the data shows, and ask what will change and by when.
1. Getting started takes longer than you expect.
Between the diagnosis, the referral, the insurance authorization, the assessment, and finding an available therapist who matches your schedule, months can pass. This is genuinely one of the hardest parts, because it happens before you have anyone on your team to complain to.
It also matters more than it feels like it should. The research found that families who moved quickly from authorization to their first session were significantly more likely to still be in services a year later, and that a shorter gap between assessment and start was associated with continuing treatment.
What helps. Ask for a specific timeline in writing at intake, with dates rather than ranges. Ask what stage your case is at whenever a week passes without news. Ask whether partial hours can start while the full schedule is being staffed, because some hours now often beat full hours in six weeks. And ask directly whether the provider has an available therapist for your times, not just capacity in general.
2. The first few weeks can look worse, not better.
New person, new demands, changes to a routine your child depends on. It is common for behavior to get temporarily rockier before it settles, and it is deeply unnerving when you were promised this would help.
Two things distinguish a normal rough patch from a real problem. The first is pairing, which is the deliberate early phase where a therapist does very little except become associated with good things. If sessions started with demands rather than play, that is worth raising. The second is how the team responds to your child's distress. The Association for Science in Autism Treatment is clear that the goal is a child who is happy, relaxed, and engaged, and that visible distress should be treated as a withdrawal of consent, prompting a change in activity and a conversation with you.
What helps. Ask how long pairing is expected to take for your child. Ask what a therapist does when your child cries or refuses. If the answer involves working through it, ask more questions. Our approach page describes how a session should be paced by the child rather than the plan.
3. Your therapist leaves.
This one hurts, and it is common. Turnover among behavior technicians is one of the persistent problems in the field. A 2024 study in Behavior Analysis in Practice interviewed technicians about why they leave and found four recurring themes: difficulty establishing and maintaining competency, difficult working conditions, a career path that feels transient or poorly defined, and dissatisfaction with pay and benefits.
Worth understanding what that tells you. Turnover is mostly a function of how a provider runs itself, not of your child. Providers with strong supervision, manageable caseloads, and real career progression keep people longer.
What helps. Before you sign on, ask about average therapist tenure. A provider that tracks it and answers is telling you something. When a departure does happen, ask for overlap sessions where the new technician shadows the outgoing one, ask how the transition is documented, and expect a temporary dip in data rather than treating it as regression.
4. Authorized hours and delivered hours are different numbers.
This one surprises almost everyone. Your authorization says 25 hours a week. What actually gets delivered is often well below that, and the gap accumulates quietly through cancellations, unfilled shifts, illness, and holidays.
The scale of it is striking. In the study mentioned earlier, only 15% of families who initiated and continued treatment received 80% or more of the hours that had been authorized for them. Separately, children receiving more than 10 hours a week were significantly more likely to still be in treatment a year on, which suggests the gap is not just a paperwork issue.
What helps. Our FAQ covers how hours are set in the first place. Ask your provider for a monthly report of authorized versus delivered hours. Ask what the provider's policy is on covering a cancelled session. And if the shortfall is persistent, name it as a specific number rather than a general complaint, because "we are averaging 14 of our 25 hours" is a conversation and "it feels like we are missing a lot" is not.
5. Progress stalls.
A goal sits at the same level for weeks. You start to wonder whether any of this is working.
Plateaus are normal in skill acquisition, and they are also sometimes a signal. The difference is visible in the data, which is exactly why data gets collected. A goal that is flat for three weeks might need a changed teaching procedure, a smaller step, a different reinforcer, or to be set aside because a prerequisite skill is missing.
What helps. Ask to see the graph rather than a verbal summary. Ask what the provider's threshold is for changing a procedure, in weeks. Then ask what specifically will change and when you will review it again. A team that can answer all three is doing this properly.
6. It works in session but not at home.
Your child does something beautifully with their technician and will not do it for you. This is probably the single most demoralizing version of the problem, because it feels like a comment on you.
It is not. Generalization has to be deliberately engineered, and if it was not built into the plan from the start, it usually does not happen on its own. This is a large part of why teaching inside the actual home, during the actual routines, matters so much.
What helps. Ask which goals have a written generalization plan. Ask for parent training that happens during the routines that are hard for you, not in a quiet room at a convenient hour. The Council of Autism Service Providers is also explicit that effective treatment requires coordination with your child's other providers, so ask how your BCBA is talking to school and to speech.

What We See in Our Own Sessions
Consider a family we will call the Levines, in Bergen County, about five months into a program for their four-year-old.
The mother emailed to say she thought therapy had stopped working. Her son had been doing well and now seemed stuck; his technician had changed in March, and she was wondering whether to look elsewhere.
Three separate things turned out to be happening. Two goals genuinely had plateaued and needed the teaching procedure changed, which the data showed clearly once someone sat down and looked at it with her. The technician change had produced a real two-week dip that had already recovered, though nobody had explained in advance that this would happen. And the family had been averaging about 60% of authorized hours since January because of a recurring scheduling conflict nobody had escalated.
None of those three was a failure of ABA. Together they felt like one, which is the point. Naming them separately made each one solvable, and the hours problem in particular got fixed within a week once it was stated as a number.
The Levines are a composite rather than one specific family, but that shape recurs constantly. What reads as "it stopped working" is usually two or three ordinary problems stacking up, none of which anyone flagged.
The One That Does Not Fit on a List
Underneath all six is the fact that this is a lot to carry. You are managing a schedule, having strangers in your home, doing homework of your own, and often doing it while parenting other children and holding a job.
I raise it because the research on why families stop is not really a story about people losing faith in the treatment. It is about bandwidth. If the program as designed is not survivable for your household, that is a clinical problem worth raising, not a personal failing to push through quietly. A good BCBA would rather restructure the plan than lose you at month nine.
Working Through Them Rather Than Around Them
Almost every challenge in this article is common, predictable, and fixable, and almost all of them get worse when nobody names them. The families who do best are not the ones who avoid these problems. They are the ones who raise them early, ask what the data says, and expect a specific answer with a timeline.
Centerbrite provides ABA therapy services to families in New Jersey, across Bergen, Essex, and Morris counties. We are deliberately small, which means your BCBA knows your case rather than one of forty, and we build plans around what your family can actually sustain rather than what an authorization permits. We will show you the hours we deliver, the data behind every goal, and what we are changing when something is not moving. If you are dealing with any of the challenges above, contact us today to get started.
Frequently Asked Questions
1. Is it normal for behavior to get worse when ABA starts?
A temporary rough patch is common as your child adjusts to a new person and new demands. What is not normal is sustained distress, or a team that works through your child's refusal rather than responding to it. If you are seeing the latter, raise it directly.
2. How long should I wait before saying progress has stalled?
There is no universal number, but your provider should have one. Ask what their threshold is for changing a procedure and hold them to it. If a goal has been flat for over a month with no change to the approach, that is a conversation.
3. Can I request a different therapist?
Yes. Fit matters, and asking is reasonable rather than rude. Be specific about what is not working, because "they seem fine, but my son does not engage with them" is more actionable than general dissatisfaction.
4. What if we cannot manage the recommended hours?
Say so early. Recommended intensity should reflect clinical need, but a schedule your family cannot sustain produces fewer real hours than a smaller one you can keep. Your BCBA can restructure rather than watch attendance quietly erode.
5. Should I switch providers if these problems keep happening?
Not on the first problem, but a pattern matters. The signal to watch is not whether problems occur, since they occur everywhere, but whether raising them produces a specific change with a date attached. If it repeatedly does not, that is worth acting on.
