This part of the form is where you fill in your personal details.
Medical qualifications should include all qualifications that allow you to undertake all of your various roles. This will include original degrees and post graduate diplomas, but might also include certificates of competence (e.g. IUD fitting) or achievement of accredited training programmes (e.g. to run warfarin services or to be a GP trainer).
It shouldn’t include CPR certificates or other knowledge / skills certificates, as these would appear under the CPD (continuing professional development) section.
Overseas qualifications and certificates should certainly be listed if internationally recognised, and probably skills listed if you judge them to be important indicating to your appraiser the training you have had for your roles.
