SIS was an in-school survey that the Office for National Statistics (ONS) carried out in 2020 and again in 2021.
This survey assessed the role of schools in coronavirus (COVID-19) transmission and how transmission within and from school settings could be minimised.
This survey closed on 31 March 2022.
What to do if you were invited to take part
If your school, child or children were selected to take part in the survey, you no longer need to respond.
Thank you to all those who volunteered to take part in 2020 and 2021.Back to table of contents
