The first session for a group is often the most difficult to prepare for. There would seem to be a choice between meeting with the whole group or each young person individually.
If it is decided to meet the whole group, then the best plan for the first session would be around group contracting. If it is one-to-one meetings with individuals, then there are a number of tools you could use.
If you have any session plans from a project tackling social exclusion in your community, please e-mail them to us at firstname.lastname@example.org so that we can share them with others.
