As assessment results come in this term, the real work begins: turning data into decisions that drive pupil progress.
For many school and trust leaders, the challenge isn’t collecting the data. It’s interpreting what matters most and deciding where to focus limited time and resources. When a large proportion of pupils fall below expected levels, the instinct may be to expand intervention or adjust the curriculum sequence. But often those numbers point to something deeper: an issue with core teaching, not dozens of individual pupil problems.
Here’s how to use your assessment data to strengthen core teaching, reduce the need for catch-up, and make smarter, system-level decisions for the rest of the year.
What your assessment data really reveals
Most schools and trusts now use some form of standardised assessment, alongside statutory checks such as the Year 1 phonics screening check. These tools play an essential role in identifying which pupils may need additional support. But the data tells a story that goes beyond individual pupils. Patterns across classes, year groups and schools reveal the strength of your core teaching.
If your results show a large proportion of pupils below expected levels in the same area, that is rarely dozens of unrelated gaps. It is a signal about the teaching they have all received.
Before you start deciding which pupils need intervention, step back and look at the system-level picture. Look for consistent weaknesses across classes, year groups or schools. Review progress over time. Consider whether specific content or skills are underperforming across the board.
This wider view turns assessment from a pupil-sorting exercise into a strategic leadership tool. It helps you pinpoint priorities, strengthen core teaching and drive sustainable improvement.
Strengthen core teaching first to avoid intervention overload
When data reveals widespread gaps, the instinct is often to expand targeted and specialist support: more intervention groups, more staff, more catch-up time. But if core teaching isn’t rigorous and consistent, you’re treating symptoms while the root cause persists.
Effective core teaching has three non-negotiables:
- Clear, assessable learning outcomes. Teachers need to know exactly what pupils should master and how progress will be checked. Vague or overly broad objectives lead to inconsistent teaching and make it hard to tell whether gaps stem from curriculum design or pupil understanding.
- Consistency across classes and year groups. Every pupil deserves access to the same high-quality teaching. When it varies widely, assessment data reflects inconsistency, not differences in pupil ability. In a trust, this also applies between schools.
- High-impact, research-informed practice. A substantial body of research shows that explicit, systematic teaching paired with scaffolded practice produces strong outcomes.
Schools and trusts that strengthen core teaching reduce their intervention pipeline, not by adding more programmes, but by ensuring high-quality teaching from the start.
Sustained improvement tends to come from approaches that fit with the assessments you already use. When choosing programmes, ask how well they work with your assessment data, so teachers can identify sensible starting points for each learner. Reading Eggs and Mathseeds are designed to help teachers do this by providing data on where each pupil is and what to teach next.
Use diagnostic assessment to target further support
Once you’ve analysed trends and reinforced core teaching, assessment data becomes a roadmap for targeted and specialist support.
Standardised assessments show who is falling behind. Diagnostic assessments reveal why. They pinpoint the specific gaps, such as phonics knowledge, fluency, comprehension, number sense, place value or calculation, that drive pupils’ difficulties.
That precision matters. Effective intervention isn’t just “more teaching”. It is more explicit, more intensive and deliberately scaffolded to close the right gaps at the right time.
Screening and standardised assessments identify who might need support. Diagnostic assessments reveal exactly what support they need.
If your data suggests that a very large proportion of pupils need targeted support, that is another signal to revisit core teaching before expanding intervention. When core teaching is strong, targeted support supplements it rather than repeating it.
For the smaller group who need more intensive help, use diagnostic information to design short-term, focused plans and monitor progress frequently. Where a pupil has identified special educational needs, this should fit within your SEND processes. Intensive support should be time-limited and aim to help pupils get back to learning alongside their classmates.
Ultimately, the goal isn’t to build larger intervention pipelines. It’s to make sure each layer of support works efficiently, so that every pupil spends most of their time in strong, well-sequenced class teaching.
Monitor what works over time
Assessment points provide snapshots, but ongoing progress monitoring turns data into sustained growth. This is where digital tools can be strategic assets rather than curriculum add-ons.
Digital programmes such as Reading Eggs and Mathseeds include built-in [reporting](link TBC) that helps teachers monitor progress week by week, turning everyday teaching into actionable data. Reporting that links to the curriculum your school or trust follows gives teachers and leaders visibility of what pupils have mastered and where more support is needed, at pupil, class and school level.
Real-time data supports quicker adjustments. If a pupil isn’t responding to class teaching, teachers can step in earlier with targeted help on specific skills. If a pupil receiving extra support is progressing well, they can move back to core teaching sooner.
The goal isn’t just to react to assessment results. It’s to create a continuous cycle of assessment, teaching and adjustment that keeps pupils moving forward.
When schools and trusts combine regular standardised assessment, diagnostic assessment and ongoing progress monitoring within a coherent system, they build provision that is proactive, data-informed and designed to help every pupil progress.
