After an abbreviated degree (MA, BA, PhD, LLB, etc.), write the year of graduation as follows:
- - LLB '98 (that is, apostrophe and two digits, regardless of the century)
Language Services and Alumni Relations use this style, so you'll see it in most every text where the names of alumni are followed by their degree and year of graduation.
This is strictly a matter of ensuring consistency at uOttawa, as other usages are equally acceptable. Many institutions, for instance, drop the apostrophe before the year (BA 78) or write the year in full (BA 1978).
