What is a ct2 doctor?

CT2 stands for Core Trainee 2, which means that the doctor has completed their undergraduate medical degree, two years of foundation year training (F1 and F2) and one year of specialisation (CT1) into one of a few general areas (e.g. medicine, surgery, paediatrics, obs and gynae, psychiatry). They are still considered to be an SHO, (Senior House Officer). After completing either CT2 or CT3 (depending on speciality), and after passing the exams to become a member of one of the royal colleges (e.g. Royal College of Physicians - which means the doctor can put MRCP after their name) the doctor will enter into ST (Speciality Training) and so will be referred to as something like ST4 or ST5. This is the equivalent of "Specialist Registrar". When the ST training is complete (between another 3 and 4 years usually) then the doctor will get a CCT (Certificate of Completion of Training), which means they can apply for a job as a consultant.

Yes, it's a little bit complicated.
