The purpose of the Diploma in Otolaryngology – Head and Neck Surgery (DO-HNS) intercollegiate exam is to test the breadth of knowledge, the clinical and communication skills, and the professional attributes considered appropriate by RCSI for a doctor intending to undertake practice within an otolaryngology department in a non-consultant career grade or trainee position.

It is also intended to provide a means of assessment for those who wish to practise within another medical specialty, but who have an interest in the field of otolaryngology and how it interacts with their chosen specialty.

DO-HNS Part 1

This is a written exam that assesses your knowledge of applied basic science and theoretical optics.

The DO-HNS OSCE consists of up to 28 active stations – including approximately five stations designed to assess clinical skills, clinical examination, clinical history-taking and communication skills; and a further 23 stations where you are presented with questions to be answered on a written question/answer sheet.

All stations allow for assessment in anatomy and physiology, pathology/histology, audiometry, otology, rhinology, laryngology, neck conditions, written communication skills, radiology, ENT surgical/medical instruments and paediatric ENT surgery. Details on exam regulations can be found on the intercollegiate website.
