Language skills
The person specifications state: 'All candidates must have demonstrable skills in written and spoken English adequate to enable effective communication about medical topics with patients and colleagues'
Confirmed via GMC registration
As GMC registration is a mandatory requirement for all applicants to have gained prior to advertised post start date, and this requires proof of English language skills, there is no need to provide any evidence of this area.
The interview will include an assessment of your communication skills but, this aside, there will be no assessment of English language other than your new employer, should you be successful, checking you have successfully gained GMC registration.
