A seven year old in a mainstream classroom sees a speech-language pathologist twice a week, an occupational therapist once, and a behaviour technician for two afternoons. Four adults, one child, four sets of notes. When his mother asks each of them how he is getting on, she gets four thoughtful answers that do not obviously describe the same boy.
That is not a sign anybody is doing a poor job. It is what happens when three disciplines with different training, different vocabularies and different funding arrive at the same child without a mechanism for talking to each other.
Three professions, one overlapping problem
The overlaps are larger than the job titles suggest. A child who shouts and leaves the table during a writing task might be doing so because forming letters is physically exhausting, because he cannot ask for a break in a way anyone responds to, or because leaving has reliably worked for a year. Those are an occupational therapy question, a speech and language question and a behavioural question, and the true answer is usually some combination of all three.
Each discipline has a legitimate first instinct. The occupational therapist looks at posture, grip, sensory load and the physical demand of the task. The speech-language pathologist looks at whether the child has a functional way to request, refuse and comment, which is the core of most communication goals. The behaviour analyst runs a functional behaviour assessment to work out what the leaving is achieving and what could achieve it more easily.
Run separately, these produce three plans that each partly work. Run together, they produce something better: a task that is physically manageable, a way to ask for a break that is faster than leaving, and a plan for teaching and reinforcing that request. The professional scope of each discipline is described plainly by the American Speech-Language-Hearing Association and by the certifying body for behaviour analysts, and the boundaries are less rigid in practice than they look on paper.
How coordination actually happens
Not by accident, and rarely by goodwill alone. It happens through three mechanisms, and it is worth knowing which ones are in place for your child.
The first is the individualized education program. Related services are written into it, goals are agreed in one room with the family present, and under the Individuals with Disabilities Education Act parents can bring outside evaluations into that meeting. A behaviour analyst's data on why a child leaves a task can change what a classroom does, but only if somebody puts it in front of the team.
The second is shared targets. When the communication goal in the speech plan and the request being taught in the behaviour plan are the same phrase, taught the same way, progress tends to be quick. When they are two different phrases, the child has to learn both and will often use neither. Families should ask whether the providers involved have actually read each other's goals, and if a provider delivers services in the school as well as the home they are better placed than most to make that happen: learn more about how a provider structures that coordination before assuming it is automatic.
The third is a named person who holds the calendar. Somebody has to notice that the occupational therapy slot and the behaviour session both fall on Tuesday afternoon, and that the child is being pulled out of the same lesson twice. That job is real and it is frequently nobody's.
Where it comes apart
Contradictory prompting is the most damaging failure and the easiest to fix. One adult waits fifteen seconds for a response, another jumps in at three. One accepts a gesture, another holds out for a word. The child learns, sensibly, that the rule depends on the adult.
Duplicated goals are the most wasteful. Two professionals both working on turn-taking, neither knowing, both collecting data, and a child spending twice the time on one skill while another goes untouched.
The quietest failure is the child becoming the point of integration, carrying information between adults who are not speaking to each other.
School-based ABA sits alongside a child's IEP and the staff delivering it; it does not replace either, and it is not a substitute for the classroom support a school is obliged to provide. What it can do, when the coordination is real, is make the three sets of notes describe one child. The test for a family is straightforward: ask each professional what the others are working on this term, and see whether the answers match.
