A record number of FABIans capped at the University of Pretoria’s Autumn Graduation 2026-05-15
Congratulations to all the FABI graduates that were capped at the recent Autumn Graduation. This ceremony saw the biggest group of FABIans yet capped with nine PhD, 29 MSc and 40 Honours degrees being conferred! This is an excellent achievement, and we wish all the graduates success in their future endeavours – either continuing their academic journey in the Institute or professional careers and further studies elsewhere. Once a FABIan, always a FABIan!
