Addressing the Challenges Facing UK Schools and Learners.
The Cover Crisis
Consistency Under Pressure
Teacher absence is a reality, but the high cost and variable quality of supply cover shouldn't compromise learning. Finding specialist maths teachers on short notice is increasingly difficult, leading to missed lessons, disrupted learning journeys, and immense pressure on school leaders. We saw a critical need for reliable, high-quality, and cost-effective cover that ensures continuity.
The Confidence Crisis
Unlocking Maths Potential
Beyond the classroom walls, particularly home learners lack confidence in mathematics. GCSE resits remain stubbornly high, and access to effective, affordable support is inconsistent. This impacts not just individual attainment but future opportunities. We believe every learner deserves the tools and support to build fluency, revise effectively, and approach maths with confidence.
