Definition
Lego Therapy is a structured small-group intervention developed by Daniel LeGoff (2004) using collaborative LEGO building tasks to develop social communication skills. Three children take defined roles (engineer, supplier, builder) and must communicate to complete a model, with the adult facilitator scaffolding the interaction.
In context for parents
Key checkpoints
- A structured small-group intervention developed by Daniel LeGoff (2004) using collaborative LEGO building tasks.
- Three children take defined roles (engineer, supplier, builder) and must communicate to complete a model.
- Roles rotate session-by-session so each child practises every communication function.
- LeGoff (2004), Owens et al. (2008) and others show gains in social communication for autistic children.
- Most effective for autistic children in late primary and early secondary, with peers of similar verbal ability.
The structure is the intervention. The three roles force specific communication: the engineer reads the instructions and tells the supplier what pieces to find; the supplier hands those pieces to the builder; the builder follows the build instructions. None of them can complete their role without communicating with the others. Roles rotate session-by-session so each child practises every communication function: requesting, clarifying, listening, problem-solving.
The evidence base. LeGoff's original research showed gains in social communication for autistic children compared with control groups, and subsequent UK studies (Owens et al., 2008 and others) replicated improvements in initiation, social interaction, and reduction of aloof behaviour. The intervention is most effective for autistic children in late primary and early secondary, with peers of similar verbal ability.
What good practice looks like:
- Three children per group, matched by language level.
- A trained facilitator (typically a SaLT or specialist teacher) who scaffolds but does not dominate.
- Weekly sessions of 45–60 minutes over a 6–12 week block, with the facilitator stepping back as the children's communication strengthens.
- The LEGO is incidental. The protocol is the active ingredient.
Where Lego Therapy works well:
- Autistic children with adequate spoken language but pragmatic communication difficulties: turn-taking, perspective-taking, repair of communication breakdown.
- Where it does not.
- With children with minimal or pre-verbal communication (where PECS or AAC is the priority first), or with children whose social difficulty is rooted in anxiety or trauma (where therapy or a different framework is needed first).
In an EHCP, Section F can specify Lego Therapy as part of a SaLT-supervised social communication programme: "weekly Lego Therapy session of 45 minutes, facilitated by a SaLT-trained adult, in a group of three matched peers".

Where parents ask about this
Parents usually find this page when a school has offered "social skills group" and parents want to know if it is structured Lego Therapy or generic chat-time. Searches include "Lego Therapy autism school", "Daniel LeGoff Lego Therapy", and "Lego Therapy Section F EHCP". A Beaakon SaLT can set up a Lego Therapy group, train the school staff to deliver it, and write Section F-grade wording.
