CNS is a thriving school that has enjoyed excellent outcomes once again in 2025. We continue to celebrate superb outcomes and individual performances amongst students sitting their GCSEs, BTECs and A levels. These results are always secured through the combined hard work and commitment of students, parents and carers and the entire staff body at our school.
