This project provides an analysis of over 500 studies to identify which specific components of targeted interventions most improve outcomes for students with special educational needs and disabilities (SEND). The researchers conclude that improving outcomes for pupils with SEND depends not on doing more, but on doing the right things well. By focusing on evidence-informed components such as explicit teaching and feedback, and considering context, schools can make meaningful progress in improving outcomes for all learners. Effective practice depends less on combining multiple strategies and more on selecting and implementing the right approaches well.
Key findings are:
- There is no one-size-fits-all solution – effectiveness depends on the subject being taught, the intended outcome and individual contexts.
- Explicit teaching is one of the most consistent drivers of improved outcomes.
- Supporting pupils to communicate their thinking improves outcomes, particularly in writing and mathematics.
- Consistent feedback and communication are strong predictors of success across studies.
- Reward-based approaches are not effective – they are consistently linked to lower outcomes.
- Retrieval and structured approaches are especially important for reading.
Implications for policy and practice:
- Carefully selected, well-implemented approaches are often more effective than complex, multi-component interventions. Simply including more components does not improve effectiveness.
- Effectiveness depends on the desired outcome and learning goal, how components are implemented and the learning context.
- Teachers and school leaders should prioritise explicit teaching and feedback and select approaches based on specific learning goals.
- Those devising interventions should avoid assuming that more complex or multi-component interventions are better.
