I have few questions about something called appraisal which I know nothing about
I got gmc licence 25/9/2019
I started working in the uk 2/3/2020

  1. Is it required from me? And when?
  2. Who will ask about it and will anyone get in touch?
  3. how much time it takes?
  4. If I didn’t do it, or was late in doing it, will it affect my licence or my record??
  5. I sent an email to the appraisal team as I created an account on the appraisal website recently but I’m afraid there will be a problem because I didn’t ask and there’s only month until my appraisal?
  6. Will they be flexible in timings?
  7. Will I still be able to have 5 appraisals if I my appraisal got delayed abit?
