the house system, which had again fallen into irrelevance, with the creation of four new houses in 2011 so that the forms system could merge with the house system. Interhouse competitions and prefect-led house assemblies were restored. Discipline has been considerably emphasised since 2011, with increased security measures, electronic staff passes and registers, and policies targeted at improving attendance, punctuality, homework completion rates and the orderliness of pupils. On 2 March 2020, the school was closed for at least a week for deep-cleaning after a member of staff contracted the COVID-19 virus on a trip to Italy. Organisation The students of Wimbledon College are organised administratively into a dual line and house system. Over the history of the college, each of the two systems has varied in importance, with the house system often falling into disuse before being revived, as was the case in 1986 and 2011, whilst the line system was briefly abandoned in 1988. In the provision of teaching, the college has been organised by departments since the 1980s, with shared departmental staff rooms and subject-specific blocs and classrooms. Certain departments cater for a range of subjects and courses, as is the case with the sciences, mathematics, humanities and arts departments. In the achievement of pupils, the college is organised into a prefectorial system (which also has limited disciplinary powers) and a colours system. Line system In accordance with traditions in English Jesuit schools, Wimbledon College students are organised into a system of 'lines' rather than year groups. The lines are: Figures (year 7), Rudiments (year 8), Lower Grammar (year 9), Grammar (year 10), Syntax (year 11), Poetry (year 12) and Rhetoric (year 13). Each line has its own head of line responsible for the discipline and pastoral care of its pupils; and each line is subdivided into eight forms to which boys belong for administrative purposes and for morning registration and prayers. Boys in Figures, Rudiments and Lower Grammar are grouped together in the 'Lower Line' whilst boys in Grammar and Syntax are placed into the 'Higher Line'. There is a Deputy Head Master for the Lower Line and a second Deputy Head Master for the Higher Line. The sixth form has its own separate head of sixth form and is largely excluded from the line system. House system Upon joining the college, each pupil is assigned to one of the school's eight houses. Traditionally, families are
