In our recent analysis of the 2026/27 fiscal roadmap, we decoded why "Return on Bandwidth" (ROB) has become the critical survival metric for MATs facing real-terms funding contractions. But as we’ve seen, balancing the budget is only half the battle if your underlying infrastructure remains locked in an analog past. While the 2026/27 cycle is about surviving the immediate squeeze, the upcoming 2028 National Curriculum Review represents a structural "Curriculum Cliff" that will fundamentally break the traditional teaching model unless the infrastructure of assessment changes today.
The UK government has officially fired the starting gun on the 2028 National Curriculum Review. To a casual observer, September 2028 feels like a comfortable horizon. But for a Head of Department or a MAT CEO, the "Planning Window" isn't years away, it’s a matter of months.
The draft curriculum will be published for consultation this spring (2026), and the final changes will be locked by Spring 2027. In the world of school leadership, by the time a policy officially "lands," the budget has already been spent. Schools don't wait for reform; they seek out the partners they trust to help them bridge the gap long before the first lesson is taught.
At Excelas.ai, we’ve performed an audit of the 2028 roadmap. Here is the surgical truth of what this means for STEM leaders and why the traditional assessment model is about to hit a breaking point.
1. The Triple Science "Marking Explosion"
One of the most ambitious proposals is the entitlement for all pupils to study Triple Science at GCSE. While this is a massive win for social mobility, it represents a logistical "black hole" for staffing.
- Moving a cohort from Combined to Triple Science isn't just about more teaching hours; it represents a 30–50% increase in high-stakes mock marking load.
- With 72% of leaders already citing staffing costs as their primary financial pressure, you cannot simply "recruit" your way out of this workload.
2. Accuracy as the New Literacy
The 2028 review places a heavy emphasis on literacy and writing assessment across all subjects. In STEM, literacy isn't just about spelling; it’s about logical precision.
Generalist chatbots (the "Nice AI") often fall into the generosity trap, awarding marks for "vague effort" rather than examiner-grade logic. To meet 2028 standards, schools need forensic accuracy.
We are moving away from "approximate marking" toward "clinical truth," where every method mark is verified against the rigid requirements of the new curriculum.

3. From "Data Autopsy" to Rapid Diagnostics
The government is pushing for the first "digital, machine-readable national curriculum". This is a clear signal: the era of the static PDF is over. The future is data velocity.
Schools can no longer afford the "three-week marking lag." To deliver a curriculum focused on "practical capabilities" and "modern work skills," feedback must be a rapid diagnostic, delivered while the learning moment is still live.
- QLA on Demand: Excelas provides real-time Question Level Analysis (QLA). Instead of a post-exam autopsy, teachers get a "Glitch-Map" of student misconceptions within hours, not weeks.
- Outcome-Led: We shift the focus from features (interactive quizzes) to outcomes (reclaiming 80% of teacher marking capacity).
The 2026 Mandate
At Excelas.ai, we aren't just watching the curriculum change, we are building the engine that powers it. We are committed to ensuring that the 2028 STEM push is defined by student success, not by the height of the "Marking Mountain."
The 2028 curriculum is coming. The question for MAT leaders is: Will you have the infrastructure to handle it, or will you still be treading water?
