Reception Baseline Assessment and ‘small acts’ of micro‐resistance
British Educational Research Journal, EarlyView.Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...
