I received a copy of past champions from an ACS old boy to complement the copy I got from a Saints old boy. These two sets of documents corroborate each other except for one year. I will favour the ACS old boy for the moment on the basis that he was actually there in 1977 and can vouch that ACS won the C Division and not RI. I’ve also got some updates from an old boy of Dunearn Secondary Technical School (renamed Greenridge Secondary) who has clarified some information.

As for the issue of Grand Slams, I had previously posted the info I got without doing the maths. Now that I have two sets of documents, I can now present my own findings. For the purposes of this website, I will consider a Grand Slam as winning the A, B and C Division championship titles all in the same year.

Why? Because the three titles have the longest track record. The three titles have been fought over since 1975, a period of 32 years. So based on that, the number of Grand Slams won by the Big Three rugby schools is as follows (in alphabetical order):

ACS — 12 Grand Slams (’97, ’99, ’01, ’02, ’03, ’08, ’11, ’16, ’17, ’19, ’22, ’24)

Raffles Institution — 5 Grand Slams (’75, ’82, ’83, ’84, ’91)

St Andrew’s — 3 Grand Slams (’74, ’79, ’87)

Number of titles won by each school, by division (in alphabetical order):

ACS – 19 As; 18 Bs; 27 Cs. Total: 64 titles

RI – 25 As; 6 Bs; 12 Cs. Total: 43 titles

St. Andrew’s – 10 As; 26 Bs; 16 Cs. Total: 52 titles

N.B. According to a reader, “A Division” was at that time also known as “Post-Secondary Division”; “B Division” as “Secondary Division” or “Senior Division”; “C Division” was variously known as “Junior Division” or “Lower-Secondary Division”.
