Employees should not be grouped by one test score alone. Start with a narrow language range, then compare speaking and writing profiles, shared communication tasks, role context, schedule and reporting relationships. People with the same job title may need different groups. People from different roles may work well together when they need to practise the same interaction.
CEFR profile;Are the overall levels and productive skills close enough for shared practice?;A large gap that leaves one learner waiting and another unable to participate
Shared task;Do participants need the same meetings, calls or documents?;A course dominated by work only one role performs
Role context;Will examples and terminology be meaningful to everyone?;Similar titles with unrelated workflows
Schedule;Can the group attend consistently across time zones?;A theoretically perfect group that rarely meets
Group dynamics;Can participants practise openly and equally?;A reporting relationship that limits honest participation
Keep the group within a narrow language range, often no more than one CEFR band, and inspect productive skills behind the overall level.
Four to six participants often gives interactive tasks enough variety and repetition. A group can run with up to eight when the format still provides active practice for everyone.
Shared recurring tasks can matter more than identical job titles.
Managers and direct reports should be placed together only when the relationship supports open practice.
Review placement during the first weeks and adjust when participation, level or task fit is weaker than expected.
