The Promises Workshop, or PWS for short, is for people who've maintained long term sobriety and have completed doing at least two SWSs. They need to have also actually worked all the 12 Steps in their entirety.
It is a 3-day programme. It is also has 4-Sunday follow-up sessions (optional) for participants to report progress, share breakdowns and get coaching on moving forward.
The 12-Step Workshop - or SWS for short is the foundation programme for people to work the 12-steps. Coached by AAs, for AAs and of AAs, the SWS is a 3-day programme. The WSLB sends one (or two) of its trainers (aka WSLs) to conduct the SWS and charges no fees for itself or its WSLs. WSLB asks that the local group that organises the SWS follow Tradition 7 of AA to meet its expenses.
