These are the key findings from the DLD Hypothetical that we help on September 17th with Professor Courtenay Norbury at the helm.
This is the context she is dealing with in England......Children and young people with special educational needs and disabilities (SEND) throughout England are set to benefit from earlier, more consistent specialist support.
Professor Courtenay Norbury is assisting to shape evidence-based standards.
From September 2026, specialists will work alongside schools to identify needs and provide support.
We went through the process of how to design a trial for this support, and navigated some difficult but important questions.....This is what we settled on!
Designing a DLD intervention trial
• Evidence gap: Few SLT-led trials are rigorous. A new trial must be scalable and meaningful to families.
• Outcomes: Vocabulary is easy to measure but may not matter most. The idea was a taught language skill as the primary outcome, then checking flow-on effects on participation and wellbeing.
• Participation: Classroom supports could be both goal and method. Attendance was a possible measure.
• Tiered support: Universal to specialist levels, with direct access to specialist help when needed.
• Consistency vs tailoring: A consistent set of responses to individual needs may achieve both. Existing programmes may help high-need children only modestly.
• Inclusion (unresolved): Several favoured including ADHD. Norbury preferred excluding autistic children initially.
• Age (unresolved): Adolescent evidence is scarce.
• Key point: Success means real-world delivery and meaningful life impact, not just task gains.
• Agreed: Ages 8–10, a language focus, and a school-based model with SPs supporting educators.
• Why 8–10: Rising literacy demands and visible difficulties, with scope for explicit language teaching.
• Measures: Primary is a language measure matched to the intervention. Secondary is participation and wellbeing, with no agreed measures.
• Identification: Many options were raised, none agreed. Unassessed children are hard to find.
• School factors: Leadership, staff commitment and competing programmes affect delivery and sustainability.
• SP role: Assess, design, coach, monitor, and provide specialist intervention.
• Implementation: Needs ongoing coaching rather than one-off training, balanced against feasibility.
• Still open: Eligibility, participation measures, dosage and trial length.
