The Predominance Rule must be applied by all Boards of Examiners except where the Director of Academic and Student Affairs has granted exemption from its use. Exemption will be granted only where it is required by validating/accrediting bodies.
Important note: the zone of consideration for predominance has been reduced from 3% to 1% for students first enrolled in 2020-21 and thereafter.
The programme mark (i.e. the mark arrived at once all the weighted individual module marks are brought together) is truncated to one decimal place. This decimal place is discarded for the purpose of determining eligibility for predominance.
For students who were enrolled prior to 2020-21, they are eligible to be considered under the predominance rule where their programme mark is within 3% of the higher classification. Therefore, the thresholds for eligibility to be considered for a higher class of degree under the predominance rule for students who were enrolled prior to 2020-21 are as follows:
67+ for consideration for First Class
57+ for consideration for Second Class, First Division
47+ for consideration for Second Class, Second Division
37+ for consideration for Third Class
For students who first enrolled in 2020-21 and thereafter, they are eligible to be considered under the predominance rule where their programme mark is within 1% of the higher classification. Therefore, the thresholds for eligibility to be considered for a higher class of degree under the predominance rule for students who first enrolled in 2020-21 and thereafter are as follows:
69+ for consideration for First Class
59+ for consideration for Second Class, First Division
49+ for consideration for Second Class, Second Division
39+ for consideration for Third Class
For a higher classification to be awarded under predominance, the following must apply:
- The programme mark, truncated to an integer, must be at or above one of the thresholds set out above; and
- At least half the contributing weighted module marks must be in the higher classification.
Predominance calculations should be made using the formula outlined in regulation 7.2.5 of the Study Regulations for Undergraduate Programmes:
Let n1, n2, n3, n4 be the number of modules at Stages 1, 2, 3 and 4 respectively in which the mark is above the relevant borderline.*
Let p1, p2, p3, p4 be the percentage weights at Stages 1, 2, 3 and 4 respectively (for example, if Stage 3 is weighted at 60%, then p3 = 60).
The higher classification is awarded if:
Bachelor’s degrees: n1 x p1 + n2 x p2 + n3 x p3 ≥ 300
Integrated Master’s degrees: n1 x p1 + n2 x p2 + n3 x p3 + n4 x p4 ≥ 300
*This calculation is based on 20 CATS modules. Where a module is worth 40 CATS, this should be counted twice in the calculation.
Discounted Modules in Predominance
If a module has been discounted under the degree classification procedures, the Predominance Rule may be applied if the candidate’s resulting mark is at or above the relevant threshold as outlined above. In such a case, the actual mark for a module that has been discounted is not included in the predominance calculation. Instead, the average of the remaining marks for the stage in which the discounted module was taken is calculated. The discounted mark is then replaced for predominance purposes with this average mark. For example, if the discounted mark is 51 and the average of the five remaining modules in the stage is 67, the predominance calculation will use the mark of 67 in place of the actual mark of 51. Predominance will therefore still be based on 18 modules (for a three-year degree programme).
