The British undergraduate degree classification system is a grading scheme for undergraduate degrees (bachelor's degrees and integrated master's degrees) in the United Kingdom. The system has been applied (sometimes with significant variations) in other countries, such as Australia, Bangladesh, Barbados, Canada, Hong Kong, India, Ireland, Jamaica, Kenya, Malaysia, Malta, Mauritius, Nepal, New Zealand, Nigeria, Pakistan, Singapore, Sri Lanka, South Africa and Trinidad and Tobago.^{[citation needed]}

The Latin honors system used in the United States is different but has some similarities.

A degree may be awarded with or without honours, with the class of an honours degree based on the average mark of the assessed work a candidate has completed. Below is a list of the possible classifications with common abbreviations. Honours degrees are in bold.

At most institutions the system allows a small amount of discretion and candidates may be elevated to the next degree class if their average mark is close to, or the median of their weighted marks achieves the higher class and they have submitted many pieces of work worthy of the higher class. However they may be demoted a class if they fail to pass all parts of the course even if they have a high average.
