The Primary School Years study is tracking children who are part of the Born in Bradford study as they grow up. It aims to collect information from 20,000 young people in an effort to understand children’s movement and cognitive (e.g. memory, attention) skills, issues around their wellbeing and happiness, and how well they are doing in school. Researchers are currently collecting information with children aged 8 to 10 years old across 90 of the city’s primary schools. On 18th April at Thornbury Primary Leadership Academy, researchers were celebrating with children at the school where the 10,000th child was tested.
