The time runs from arriving at A&E until the patient is admitted to a ward, transferred or sent home, so waiting for tests and for a bed is part of it. This is a fact about the A&E department, not a grade or a verdict. Departments see different patients: one that admits more people, or takes the most seriously ill, will often have longer times.
