“How do I get to be a GP with a special interest in mental health?”
The RCGP are clear that no specific accreditation is needed. Instead, there have created some frameworks which support you identifying in the competencies you need to develop. Even if there isn’t a framework for the area you work in, you can identify the areas you need to be proficient in to do the role, and then evidence these in your appraisal and CPD.
See the section on CPD for resources to help you do this, or visit the forum to discuss experiences with your colleagues.
