The aim of CASS was to find out the proportion of people working in education in Scotland who have had COVID-19 by testing for antibodies in their blood. This type of test looks at whether someone has been infected in the past.

By testing people through the 2020/21 school year, CASS aimed to track if this changed over time. This information will help inform how we manage and introduce health measures in educational settings to minimise the risk of infection.

Survey Participant Information

Any member of staff working in an educational setting was able to register their interest in participating. Staff were sent a home testing kit which required them to take a small finger-prick blood sample. This was then returned by post to the laboratory for testing. The results were returned to staff and analysed by Public Heath Scotland to improve our understanding of COVID-19 in this group.

An information pack for participants was developed. This provided additional information relating to the survey and also a promotional poster.
