Newly arriving first-year students from 2020 Cohort 1 were accommodated on campus in cluster flats treated as a “household” and attended teaching sessions in “bubbles” through the study period to avoid exposure to larger groups of people. Final-year students mostly lived off campus and attended clinical rotation placements in the community during this year of study. The P-ATS start for eligible final-year students was staggered since they joined at different times according to academic timetabling and the start date of relevant placements. Final-year students joined the programme at different times, had fewer tests offered in total, with some students taking only one test, and others taking more if they changed rotation placement during the study period. Therefore, the total number of tests offered varied between students, although the testing offers and start date were consistent for those who were in their first year. The first- and final-year students who accessed P-ATS, therefore, had a different experience of both the service (with only first years offered the complete programme), and of university life more broadly.
