The statutory requirement to provide RSHE education is still in place from September, and schools should continue to prepare for this date where possible. However, due to the coronavirus and closures, schools who are not in a position to implement fully from September have until Summer term 2021 to do so.
In such cases, the DfE suggests a phased approach to ensure teaching begins as soon as possible, and that schools should consider prioritising curriculum content on mental health and well-being.
