Hung up on semantics here: PGY-1, 1st year of residency, after the first year you are referred to as a resident. Title hangs on you for 12 months that's all. No big deal.
However, in the UK, the term "consultant" is usually used to refer to a specialist (as apart from a GP).
The term attending in the US is used to refer to someone who has finished training, whether as a generalist (usually referred to as FM here) or a specialist.
