British undergraduate degree classification
In the United Kingdom, medicine is usually taught as an undergraduate course, with graduates being awarded a master's level qualification: normally the conjoined degrees of Bachelor of Medicine, Bachelor of Surgery (MBBS, BM BCh, MB ChB, etc.) although at Queen's University Belfast (and universities in Ireland) Bachelor in the Art of Obstetrics (BAO) is added, and at some universities only the Bachelor of Medicine is awarded - all of these have equal standing. Unlike most undergraduate degrees, the MBBS is not normally considered an honours degree, and thus is not classified into first class honours, etc. Students may be awarded "Merits" and "Distinctions" for parts of the course or the whole course (depending on the institution) and "Honours" may be awarded at some institutions for exceptional performance throughout the course (as a grade above Distinction).
Honours degree
In Ireland, undergraduate degrees fall under two levels in the National Framework of Qualifications (NFQ) of the Quality and Qualifications Ireland (QQI). Courses of study at level 7 take three years and are awarded an Ordinary Bachelor Degree (180 ECTS credits) whereas a course of study at level 8 typically takes four years for an award of a Honours Bachelor Degree (180-240 ECTS credits). There is also an equivalent award at level 8 of a Higher Diploma which follows a course of study of one year duration (60 ECTS credits), such Higher Diplomas are designed for holders of either Honours Bachelor Degree or Ordinary Bachelor Degree who wish to study in a different field of learning than their initial award.
