Impact on achievement
Our intervention programmes are designed to target support where it’s needed most, making effective use of Pupil Premium funding. They align with the National Curriculum to strengthen core maths learning, boost attainment and confidence in number and calculation, and make maths enjoyable through engaging activities and games. At the same time, they empower teaching assistants with training, resources, and subject knowledge, while demonstrating real impact through clear evidence of progress.
