Postgraduate teaching in psychiatry has always been a function of the provincial mental hospitals, but nothing before has equalled the expansion of theoretical teaching which has taken place over the past ten years. At the heart of the training of a psychiatrist, however, there is the National Health Service job with its own demands, where the practical clinical skills are acquired. The job has not changed much, even though the arrangements for theoretical instruction have improved. Yet changes may be possible which will make the registrar's job more efficient as an educational experience by removing the unsystematic and random elements.
