Designing the missing middle: a practice-informed case study of translating autism knowledge into family-school capacity

Purpose This paper aims to present a practice-informed case study of a low-load autism parent partnership model in mainstream primary schools. It addresses the “missing middle” between autism knowledge and family–school capacity, arguing that relational, accessible and practical structures are needed to make knowledge usable. Design/methodology/approach This paper draws on practitioner reflection, school-approved parent partnership work across two mainstream primary contexts, community-facing engagement, visual resource development and anonymised feedback. It is not an intervention trial or effectiveness evaluation; feedback is used as design learning. Findings This case study identifies access load as a barrier to early autism support, encompassing emotional, linguistic, cognitive, cultural, relational and practical demands. The model used a four-part rhythm: one theme, one accessible resource, one shared conversation and one practical takeaway. Research limitations/implications This context-specific case study cannot demonstrate impact on child or family outcomes. Future research should examine reach, acceptability, implementation consistency, SENDCo workload, home-school communication, sustainability and which families do not enter the model. Practical implications The model offers SENDCos and school teams a proportionate structure for autism-informed parent partnership without creating a fixed parent-training programme or transferring responsibility onto families. Social implications The model may support more equitable, lower-pressure access to autism-informed parent partnership, particularly for families facing stigma, service mistrust, language barriers or uncertainty about diagnosis. Originality/value This paper introduces access load and the missing middle, reframing autism parent partnership as a design problem rather than parental willingness or information availability. It offers a low-load rhythm for translating autism knowledge into usable family–school capacity.
