Starting School: a large-scale start of school assessment within the ‘Born in Bradford’ longitudinal cohort [version 1; peer review: 1 approved with reservations]

The Born in Bradford (BiB) cohort of 13,776 children born between 2007-2011 and their parents provides a rich data resource for researchers exploring protective and risk factors influencing long-term developmental and health outcomes. Educational attainment is a critical factor related to later health. Literacy and communication, fine motor skills and social and emotional health are key ‘early’ predictors of educational attainment and can be used to identify children in need of additional support. We describe our BiB ‘Starting School’ data collection protocol which assessed literacy and communication, fine motor skills and social and emotional health on 3,444 BiB children aged 4-5 years old. These measures supplement the existing dataset, and complement the routine educational, health and social care data available for the cohort.
