Sekolah Menengah Kebangsaan All Saints is a single-session secondary school located in Jalan Teluk Likas of Kota Kinabalu, Sabah, Malaysia.

[4] The development of Anglican Church schools was inspired by foreign settlers to provide education to their children.

King Edward VII School at that time, under the charge of Mr. Chai Ah Soon, was basically a one-man show, for he doubled as the headmaster and form teacher.

The students learned simple arithmetic, English grammar, reading, writing and Bible studies.

Besides, meetings and social functions were held in King Edward VII School as it was difficult to find suitable premises in Jesselton for these purposes.

Later, on 1 September 1909, King Edward VII School was moved to a land at Karamunsing, granted by the Court of Directors of the British North Borneo Company.

The government had to stop its financial assistance and parents were unable to pay for the schooling expenses.

In December 1934, Cambridge University Local Examinations were held in All Saints School for the first time in Jesselton.

In June 1953, the Governor of North Borneo, Sir Ralph Hone laid the foundation stone for building All Saints' one-storey block.

On the same day, the foundation stone of the new multipurpose hall was laid by the Anglican Bishop of the Diocese of Sabah, Rt.

Canon Lee by the then-president of the Kota Kinabalu Municipal Council, Datuk Peter D. Cheong.

On 14 October 1992, the ground-breaking ceremony was officiated by then-state cabinet minister, Datuk Wilfred Bumburing.

On the same day, Datuk Wilfred and Bishop Yong unveiled a plaque, to mark the start of construction work the building.

She also developed the Form 6 Block, the workshop, the school archive, the conference room, the chapel, the new grandstand, the covered walkway and the installation of the closed-circuit television camera (CCTV).

She upgraded all of the students' and teachers' washrooms, the classrooms, the floor tiling and improved the school landscape.

Non-core classes such as geography, physical and health education, visual arts, music, living skills, Chinese, Kadazan-Dusun and Tamil languages are also offered to the students as elective and optional subjects.

This event is held annually in November to recognize and reward students who have contributed and served the school with dedication throughout the year.

Certificates and awards for Form Six students who have displayed outstanding academic performance throughout the three semesters are distributed as well.

This annual run, held in January, is aimed at inculcating an athletic culture among students and raising awareness of the importance of staying healthy.

The most-awaited part of the night is the nomination of individuals for the Best Dressed Award followed by a photo session of all prefects and teachers present.

All participating Interact Clubs from each school are tasked to choose a country as their theme to raise awareness for the chosen cause.

For many years, students from All Saints School have been actively involved in various competitions, such as the Young Inventors Challenge (YIC), Kuala Lumpur Engineering Science Fair (PISTEK), National Mathematics and Science Olympiad, Singapore and Asian Schools Mathematical Olympiad (SASMO) and the Malaysia Brain Bee Challenge (MBBC).

All Saints School has performed capably at the national level in cross country running, badminton, track and field, tennis, table tennis, squash, ten-pin bowling and sailing and has performed exceptionally in gymnastics at the international level.

All Saints School was awarded the Champion (Group Category) of the 2019 National Young Inventor's Journal Competition held in Publika Solaris Dutamas, Kuala Lumpur after shortlisted from over 70 participating groups across the country and competing with 3 finalists.

All Saints has international links with the Arima Senior High School, in Sanda, Hyōgo, Japan through the Global Generation Programme which started in 2005 and continues bi-annually.

[9] Students who are selected to participate in the student-exchange programme travel to Arima Senior High School in Japan, accompanied by teachers.

The bi-annual programme allows All Saints students to experience the life and culture of Japan and to make Japanese friends.

Teaching and learning methods in STEM fields as well as opinions on global warming, oceanic pollution and other crucial environmental issues abroad are exchanged.

Since 2015, All Saints School has established international relations with Hokkaido Sapporo Keisei High School in Japan through the Sakura Science Programme[11] to promote establishment of a mutual research scheme and a high school-university international partnership (Rakuno Gakuen University of Hokkaido, Japan and Universiti Malaysia Sabah), to help raise the next generation who will contribute to solving Asian challenges of biodiversity and water resources.

Furthermore, the Kota Kinabalu Wetland Centre (KKWC), is a 24-hectare mangrove forest located a five-minute drive away.
