Pupils are grouped in three ways: Alphabetically, by Class and by Year Group. If required, other pupil groups can be created, e.g. pupils can be grouped by Subject or by Set. In SCO these groups are known asCohorts. Cohorts can be created manually, e.g. for music lessons or Extended Day Clubs, or by importing the data from the school pupil management system (for example SIMS, Progresso, CMIS, Scholarpack, Bromcom, Arbor, PupilAsset, Integris G2), e.g. for Geography set.
