Grading Conventions

Further information on the calculation of grade point average (GPA) where mixed grading conventions are used

As of from January 2011 all results are given in percentage format only.  In most cases, all results in the award year will be in percentage format and the calculation of the award results will be purely a numeric calculation. In some cases, however, where a student has module attempts from a previous year or years, an award will be determined based on a mix of grades, some Alpha (that is, A, B+, B, C etc), some Numeric. In these cases, Alpha grades previously awarded will - for the purposes of arriving at the calculation only - be converted into numeric equivalents according to the table below.

To ensure that there is no disadvantage, the Institute will verify the overall average through a parallel calculation that will convert the numeric marks to their equivalent Alpha grades and then calculate a GPA and overall award based on the GPA equivalent of each alpha grade in Table 2 below. In other words, this will calculate the GPA as if all the grades had been entered as Alpha grades. This check figure will be available to examination boards for verification purposes.
