„Since 2016, Sweden has implemented a policy whereby diagnostic tests on students’ previous schooling and their level of academic knowledge are conducted within two months of the student’s arrival at school. Subsequently, additional tests are conducted in different school subjects. No more than two months after the student is enrolled in a school, the principal makes a decision regarding his or her grade and placement in either introductory (separate) or regular class.“
