I thank my hon. Friend for raising this important issue. Reducing transmission in schools is of the utmost importance to me, and I will do everything in my power to keep schools open. We have provided guidance to settings regarding testing arrangements on their return in January.
As the Secretary of State knows, carbon dioxide monitors can help to identify quickly where ventilation needs to be increased in classrooms. Will he give an update on the roll-out of these monitors in schools?
Over 99% of eligible settings have now received a CO2 monitor, with more than 320,000 now delivered. Final deliveries will be made before the end of term. Feedback from schools suggests the monitors are a helpful tool in managing ventilation, sitting alongside the other protective measures in place to manage transmission.
