CLEAPSS Supporting practical science and technology

Latest news from CLEAPSS..
COVID-19 (Coronavirus) in Schools
CLEAPSS Office is open 8.30am to 4.30pm


CLEAPSS COVID guidance is based on the latest version of the DfE’s COVID protocols. To date the DfE have not removed the requirement to clean or quarantine equipment when it moves between bubbles of pupils, therefore we are unable to change our guidance on this aspect. 

We will continue to monitor the DfE protocols and as and when changes are made to the DfE's requirements around cleaning/quarantining of equipment we will update our guidance. 

In the meantime we continue to impress on the DfE the negative impact that the requirements around cleaning and quarantining are having on the amount of practical work that schools are able to do with pupils.
