Honours
In England, Wales and Northern Ireland there are two different types of degree: Honours degrees and Ordinary degrees. The degrees awarded carry a designation related to the broad subject area such as B.A., B.Sc, B.Eng etc. Most degrees are now honours degrees, with an option not to take honours, and the standard length of a Honours bachelor's degree is 3 years. Prior to the mid 20th century all candidates would take an Ordinary degree and then be selected to go on for a final year for the Honours degree.
Honours degrees are of a superior academic standard. However the practice of writing 'Hons' as part of the degree designation is unofficial and is considered by many as an affectation. An Honours degree is always awarded in one of four classes depending upon the marks gained in the final assessments and examinations. The top students are awarded a first class degree, the next best, an upper second class degree (usually referred to as a 2:1), the next a lower second class degree (usually referred to as a 2:2), and those with the lowest marks gain a third class degree. An Ordinary or unclassified degree (which does not give the graduate the right to add '(Hons)') may be awarded if a student has completed the full honours degree course but has obtained a very low pass mark which is insufficient to merit a third-class honours degree.
