YOUR QUESTION. A CLEARER NEXT STEP.
Is ABA usually one-on-one or in a group?
ABA is most often delivered one-on-one, especially when teaching new skills, because a single therapist can tailor teaching to your child's pace and interests. As skills grow, small-group work is added to help your child use them with peers — so a good programme blends both, with the balance reviewed as your child develops. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

Will your child be learning alone with one therapist, or alongside other children? The honest answer is — usually both, at the right times.
In short
Applied Behaviour Analysis (ABA) is most often delivered one-on-one, with a single therapist working closely with your child so teaching can be tailored exactly to their pace, interests and goals. As skills grow, small-group work is gently added to help your child use those skills with other children — turn-taking, sharing, waiting and play. So it is rarely either/or; a good programme blends both, with the balance shifting as your child becomes ready.
How the format works
- One-on-one is the foundation. Early teaching of new skills — communication, daily-living routines, play, attention — works best when one therapist can adjust moment to moment, repeat just enough, and follow what motivates your child. This intensity is where most early progress is built.
- Group work builds the bridge to real life. Once a skill is steady one-on-one, it needs to generalise — to work in a busy room, with peers, when no single adult is focused only on your child. Small structured groups, paired play and naturalistic group activities are where social skills truly take root.
- The blend is personalised. A young child new to therapy may begin almost entirely one-on-one. An older child preparing for nursery or school may spend more time in peer and group settings. The mix is a clinical decision, reviewed as your child grows — not a fixed rule.
The goal is never therapy for its own sake, but skills your child can carry into the classroom, the playground and the family table.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Notice whether your child can use a new skill only with one familiar adult, or also with other children and in busier settings — this readiness signals when to introduce more group work.
In everyday life
Once your child masters a skill with you alone, gently practise it with a sibling or one playmate nearby — this small step helps the skill carry over into group and real-life settings.

Bring your questions to a first visitQuestions families ask
Is ABA always one-on-one?
No. ABA most often begins one-on-one because new skills are easiest to teach with a single therapist adjusting to your child. As skills become steady, small-group activities are added so your child can use them with peers.
Why is group work added to ABA?
Skills learned one-on-one need to generalise to real life — busy rooms, peers, sharing and turn-taking. Structured small groups help your child carry skills into nursery, school and play.
Who decides the balance between one-on-one and group?
It is a clinical decision made by your child's therapy team and reviewed as your child grows. A younger child new to therapy may start mostly one-on-one; an older child preparing for school may do more group work.
