Saint Mary's School, commonly known as just Saints, is a private boys' day school owned by the Roman Catholic Archdiocese of Nairobi. It is a combined primary and secondary school, which offers KCPE, KCSE, IGCSE and IBDP certification. As a boys' school, female students are only allowed to enroll for the IB Diploma Programme.
The school's motto is "Bonitas, Disciplina, Scientia", which is Latin for "Goodness, Discipline, Knowledge".
In 1946, the school was moved to a temporary structure on an 85-acre site on the land belonging to the St. Austin's Mission in the Muthangari area of Westlands. The present-day school buildings were completed in 1954, including the twin towers that stand at the school's quadrangle and the St. Austin's Catholic Church, which sits beside the school's parking area. In between the towers is the staff room where teachers convene for meetings and take their breaks, which used to be the school's library.
From the outset, Saints has always had a combined primary and secondary school. Although only boys are admitted to the primary and secondary schools, girls (along with boys) are admitted to the International Baccalaureate diploma course which is a post-O-level programme offered by the school since 1982. Entrants are chosen on the basis of their KCSE and IGCSE results. The school year runs from January to November.
Students are encouraged to participate in extra curricular activities, which include sports, clubs, music and drama. This is one of the aspects of the school. All the school's sports teams are nicknamed "Saints", also the school's nickname.
Since 1971, the school has been staging a musical every year, open to the general public. The musical week runs on specific dates from Tuesday to Saturday. The school has staged its own productions of famous plays such as The Mikado, The Yeomen of the Guard, The King and I, Joseph and the Amazing Technicolor Dreamcoat,The Sound of Music, Sarafina!, Cinderella, Oklahoma!, The Music Man, Ipi N'tombi, Aida,Zambezi Express,Amazing Grace (the musical).
In line with its Irish origins, rugby is a central concern and a key activity designed to forment "spirit". Their rugby team have recently won the Prescott Cup twice in a row (2008–09) but lost to Mang'u High School in the 2010 finals. They also host and have won the Blackrock Rugby Festival 10 times so far (1994–99, 2004–05 and 2010–11) and have been runners-up 7 times so far (1988–89, 1992, 2000, 2002–03 and 2006), recently winning the 28th edition final, alongside many other cups. They also won the 2014 Nairobi county rugby championship against bitter rivals Nairobi School at Upperhill school Nairobi, under head coach Thugana Riunga and Assistant coach Anthony Nyandigisi. It was a good time for the team considering the teams poor performance between 2012-2013.
Football is also a popular sport in the school, with recent honours in the recent past, such as the Keele Plate runner-up finish in 2010 and the Strathmore Under-11 Football Cup win for the under-11 team in 2008. The high school team of 2011 was praised as the team to progress the farthest in all tournaments, including the Nairobi Provincial Schools' Tournament.
Under the guidance of some of Kenya's coaches, the school has consistently produced strong swimmers who have dominated local competitions and gone further to represent Kenya in continental and international championships.
