With local SEND reform plans due by 19 June, many councils are working to translate the national policy into something deliverable, financially sustainable, and grounded in local reality. The challenge is not just meeting the deadline. It’s producing a plan that can genuinely inform decisions about provision, spending, and outcomes – not one that’s credible on paper but difficult to act on.
At Mime, we’ve supported over 50 local authorities with SEND analysis and forecasting. The most effective analysis and forecasting for planning is not always the most complex. It is analysis built on clear, adaptable modelling with a direct link to delivery.
Here are six practical ways to strengthen your local SEND reform plan.
1. Build a model that can adapt, not just predict
Most SEND models are designed to statically forecast demand. In the current environment, that is not enough. Reforms are still evolving, and local understanding will continue to develop. A static model that cannot adapt will quickly lose its value. Instead, focus on building an approach that allows you to:
- Adjust key assumptions, such as request rates and need profiles,
- Test different scenarios as policy and local context change,
- Incorporate emerging intelligence without rebuilding from scratch.
The priority is not technical complexity. It is giving leaders the ability to explore “what happens if…” and make informed decisions under uncertainty.
2. Start with person-level data, not aggregates
High-level aggregate data may be sufficient for reporting, but it is a weak foundation for planning. Effective SEND reform plans are built on a detailed understanding of how need varies across the system. This includes:
-
Differences by age group,
-
Variation across localities,
-
Patterns in specific SEND needs and provision transitions.
Working at person level allows for more accurate and flexible projections, particularly when planning provision and assessing sufficiency. Without this level of detail, it is difficult to make confident decisions about future demand or service design.
3. Be explicit about data quality
All local authorities face data quality challenges. What matters is how they are handled. Common issues include inconsistent need coding, gaps in historical data, and misalignment between datasets. Plans that overlook or ignore these issues are harder to rely on and harder to defend. Stronger SEND reform plans take a more transparent approach. They:
-
Clearly identify known limitations,
-
Apply sensible adjustments where needed (for example, aligning SEN2 data with school census records),
-
Build in processes to improve data quality over time.
This strengthens confidence in the analysis and supports more robust decision-making.
4. Align forecasts with your provision strategy
A common weakness in SEND reform plans is treating projections and provision planning as separate exercises. In practice, they need to work together. Demand projections should inform decisions about future provision, including specialist placements and capacity. At the same time, planned changes to provision should be reflected in forecasts and financial planning. For example, if your model shows rising demand for specialist secondary places, that should directly shape your capital strategy. As provision changes, those assumptions should then be fed back into the model. This iterative approach helps ensure that plans are both realistic and deliverable.
5. Anchor your model in population trends
SEND demand is linked to wider demographic change. Plans that rely solely on historic SEND trends risk under- or over-estimating future need, particularly in areas experiencing population growth or decline. Robust modelling should take into account:
-
Birth rate trends,
-
Migration patterns.
Incorporating these factors allows your plan to look forward with greater confidence, rather than relying only on past patterns.
6. Handle small numbers carefully
SEND planning involves some relatively small cohorts, where percentage changes can be misleading and create unrealistic volatility in projections. For example, a 20% increase in a group of 15 children tells a very different story than the same growth in a group of 200. With small numbers, to maintain stability and credibility:
-
Focus on multi-year trends rather than single-year changes,
-
Group categories where appropriate to reduce volatility.
This helps ensure that decisions are proportionate and based on reliable signals.
What distinguishes a strong SEND reform plan?
The plans that are most useful to senior leaders tend to have three characteristics:
-
Adaptable modelling, rather than fixed forecasts,
-
Granular data, rather than high-level averages,
-
A clear link between analysis and delivery, including provision and financial planning.
These elements allow the plan to support real decisions, not just meet statutory requirements.
Why this matters
Getting this right goes beyond compliance. A well-constructed SEND reform plan provides a foundation for:
-
Reducing reliance on independent provision,
-
Making informed investment decisions,
-
Improving outcomes for children and young people with SEND.
How Mime can support
Many councils already recognise that building a robust, adaptable modelling approach now is critical, not just for the SEND reform plan due by 19 June, but for what follows. At Mime, we support councils to:
-
Strengthen SEND data and forecasting,
-
Develop flexible, scenario-based models,
-
Align projections with practical, deliverable provision strategies.
