Dfe tells us that... Biennial science sampling tests for pupils at the end of KS2 will take place in June 2016. The tests will not be taken by whole cohorts. Instead, a sample of approximately 9,500 pupils will be randomly selected, based on five pupils from 1,900 schools. In addition, of the 1,900 schools selected, a sample will be selected to participate in the pre-test trialling of the 2018 science sampling tests. Five additional pupils from each school will take these tests. Schools that are selected have a statutory obligation to participate. Can anyone say when participating schools will be told of their selection, and who the lucky five pupils are?
