CLAPA is committed to strengthening links between the cleft community and cleft researchers. This includes keeping our community up to date about the latest research and how they can get involved, as well as helping researchers make their studies accessible to all.

We believe patient and public involvement (called ‘PPI’) in research is absolutely vital to make sure the right things are being studied in the right way, and we have been thrilled at the commitment of research teams in recent years to involving the cleft community at all stages of their work.

This section of the website goes through how people in the cleft community can get involved with research, both as a participant, and as part of a team evaluating how the research is designed in the first place. It also goes through how CLAPA can help researchers with publicising their projects and making them more accessible to the cleft community.
