Co-treating with an occupational therapist in speech sessions

When a speech-language pathologist and an occupational therapist share a session, children often respond with more engagement than they do in back-to-back individual appointments. Joint sessions make therapeutic sense because regulation, motor planning, sensory processing, and language rarely sit in neat boxes inside a real child's day. A kid struggling to sequence a two-step verbal instruction is usually also managing body position, attention, and tactile or vestibular input. Bringing both professions into one space lets us target those overlapping skills in a single, functional block.

In Australia, where many families access therapy through the NDIS, a Chronic Disease Management plan from their GP, or a school-based allocation, co-treatment is becoming a practical way to stretch funding and reduce appointment fatigue. It also reflects how multidisciplinary teams work in paediatric hospitals from Perth to Brisbane and in community health centres across regional Victoria. The model is not a shortcut, though. It runs on shared planning, clear roles, and a willingness to slow down and coordinate.

Why co-treatment makes clinical sense

Communication is not just about words. A child might know the vocabulary for "help" or "more" but be unable to reach for a picture card because their postural control is compromised. An OT colleague can adjust seating, offer a fidget, or grade the sensory environment while the SLP waits for that teachable moment. Both clinicians are watching the same child at the same time, which means we can interpret behaviour together rather than passing notes after the fact.

Co-treatment also respects the way families live. Parents who drive in from Dubbo or the outer suburbs of Adelaide often tell me that juggling separate weekly appointments is the hardest part of the week. When the two disciplines align, families see one consistent message about how their child learns, regulates, and connects. The same carryover can happen in the classroom, where a teacher watches us model how language goals sit alongside fine-motor or self-regulation goals during a single learning activity.

Building the partnership before the first session

The relationship between the two clinicians is the real engine of co-treatment. Before scheduling a joint session, I usually spend time getting to know how the OT works, what their priorities are, and what language we can borrow from each other. A quick coffee in a Collins Street café or a thirty-minute phone call can be more useful than a formal meeting. We discuss the child's history, the parent's concerns, and the goals each of us has written up.

It helps to share a one-page summary so nothing important lives in separate clinical files. In private practice and in the public system, both professions are bound by the Australian Privacy Principles and AHPRA registration requirements, so written consent from the family to share information is essential. Once the family is on board and the paperwork is sorted, the joint session becomes a clinical event, not an admin headache. If you are new to co-treatment, you might find it useful to read about AAC use during play because the same collaboration principles apply when a child is learning to use a speech-generating device alongside motor and sensory goals.

Planning shared goals that respect scope

Goal alignment is where many co-treatment partnerships either thrive or stall. I prefer to start with one functional goal that both professions can claim a stake in, then add profession-specific targets underneath. For example, a child might have a shared goal of initiating a request with a peer during a construction activity. The SLP focuses on the linguistic forms and the social scripts, while the OT focuses on grasp, bilateral coordination, and the sensory tolerance required to sit at the mat for five minutes.

How responsibilities typically divide in a co-treatment session is worth mapping out before the first joint session. Australian clinicians can adapt the starting points below to suit their setting.

Area of focus	Speech-language pathologist	Occupational therapist
Pre-session setup	Choose target vocabulary, prepare visuals, plan language elicitation	Adjust seating, plan sensory tools, consider lighting and noise
During the activity	Model language, recast responses, prompt for carryover	Grade motor demands, scaffold regulation, support tool use
Behavioural cues	Interpret communication signals, respond to vocalisations	Interpret sensory triggers, support self-regulation strategies
Documentation	Report on speech, language, and social communication data	Report on fine motor, gross motor, and sensory regulation data
Family feedback	Advise on language stimulation at home and kindergarten	Advise on positioning, routines, and sensory strategies at home

When we are explicit about who is doing what, the child experiences one calm, integrated session rather than two professionals competing for the lead. It also protects scope of practice, which matters when reporting back to the NDIS, the school, or a funding reviewer.

Structuring a session that actually flows

A well-run joint session feels less like two people taking turns and more like a duet. We usually begin with a shared arrival routine, where both clinicians greet the child together, explain the activity, and let the OT set up the physical space while the SLP chats through the picture schedule. This kind of opening sets a predictable rhythm and gives the child time to settle their body and attention before the language work begins.

The middle of the session is where the activity itself happens. I try to choose tasks that have a natural language demand built in, such as cooking, obstacle courses, or craft. The OT can grade the motor or sensory challenge while I focus on the communicative intent the child needs to express. If the child becomes dysregulated, the OT takes the lead on regulation strategies while I follow the child's communication signals, including non-verbal cues. Older students working on figurative language benefit from co-treatment too, and you can read more about idioms and figurative language for older students in that same guide. Closing the session with a short, shared review helps the child carry the learning into the next setting.

Working within NDIS, schools, and private settings

Australia's funding and service landscape shapes how co-treatment is delivered. Under the NDIS, joint sessions can be claimed when both providers are present and the activity relates to goals in the participant's plan. Reports need to show distinct, discipline-specific input, which is another reason why the goal-sharing table above is worth completing. Some families use a Chronic Disease Management plan through Medicare for allied health sessions, and in that case the rules around concurrent provider attendance differ, so it is worth checking the latest MBS guidance or calling Services Australia.

In schools, particularly in NSW and Queensland, allied health professionals often work under a service agreement with the education department. Co-treatment sessions can happen in the classroom, in the therapy room, or on the playground, and they should always link back to the student's individual plan. Speech Pathology Australia and Occupational Therapy Australia both publish position papers on collaborative practice that are useful references when you are advocating for joint sessions in a school review meeting. Regional and remote families sometimes access co-treatment via telepractice with a local OT present, which has its own logistical considerations around consent, documentation, and equipment.

Troubleshooting common challenges

Even with strong planning, joint sessions can go sideways. One common issue is parallel talk, where each clinician narrates their own discipline without listening to the other. A simple fix is to agree on three key words or phrases that the lead clinician will use during transitions, so the second clinician can step in without verbal collision. Another is goal drift, where one professional slips into teaching the other's target. Reviewing the shared goal sheet at the start of each session keeps everyone honest.

Some OTs and SLPs worry about losing their professional identity in a co-treatment model. In my experience, the opposite happens. Children often make faster progress when the professionals trust each other enough to share the floor, and families notice the difference. It is also worth remembering that co-treatment is not the right fit for every child or every goal. Some children need individual, intensive input before they can benefit from a joint session, and some goals are simply too discipline-specific. Knowing when to step back into separate sessions is just as important as knowing when to combine them.

If you are ready to give co-treatment a go, start with one colleague, one child, and one clear shared goal. Reach out to an OT you already trust, set a date, and treat the first session as a learning opportunity for both of you. Your clinic, your school, and most importantly the families on your caseload will feel the benefit within a few short weeks.
