GEM Focus Groups

Introduction

The hallmark of GEM workshops is its community-led workshop-style sessions, carried out through focus groups. Interested in applying to run a focus group and are not sure how to do it? Are you currently running a focus group and need ideas for how to achieve the workshop-style in your focus groups? Advice from previous focus group leaders on proposing and running a focus group, updated in October 2019, is available here.
