The first Principal (formally entitled "Master"), Mr. Fung Fu, received education in the US and was deeply influenced by the development of democracy in the West.

During 1905, Mr. Fung held the post of a translator at the China Daily, a newspaper founded by local intellect Chen Shao-bai, Dr. Sun Yat Sen's dearest friend in his juvenile years.

According to the Government Notification in 1880, the appraisal of the Education Bureau reported that Saiyingpun School had an outstanding performance, and thus was classified as "Rank 1".

According to an article published in the 2002nd issue of the Christian Weekly, it stated that Kong and Lau used to be students in "Saiyingpun Fung Fu School".

In June 1905, Mr. Alfred Morris replaced Mr. W. H. Williams as the Master, the latter was transferred to Victoria British School earlier in January that year.

For instance, in the 1922 Report, it was stated that students in Saiyingpun School excelled in map reading, handwriting, English conversation and composition.

Students also received recognition in their extra-curriculum activities, for example, the Ambulance Division got Distinction of Winning Ralph Shield(Report of Director of Education).

Sometime after the construction of St Anthony's, probably because having two churches in such close proximity was seen as an inefficient use of holy land, the Sacred Heart Chapel was converted into an orphanage and school under the care of the Canossian Sisters – the Ling Yuet Sin Kindergarten of the present day.

In 1920, there was a requisition order by government authorities for a portion of Inland Lot 755, the section where the Church of St Anthony stood.

Site formation, the foundation works and construction of retaining walls were undertaken by Messrs. Foo Loong & Co. in the same year and the superstructure was erected by Messrs. Kin Lee & Co. in 1924.

[citation needed] While the school was enjoying its prosperous days, the Pacific War broke out after the Pearl Harbour Incident in December 1941.

In 1951, the government gave a green light on additional buildings for King's College and decided to restore its status as a secondary school.

In the same year, an extra Secondary Upper Six was operated to make places available for students who planned to sit for the revised Hong Kong University Matriculation Examination.

[33] In 1968 64 distinctions were obtained by King's College students in the Hong Kong University Matriculation Examination, an unprecedented achievement.

Madan was appointed principal and King's students continued to achieve magnificent feats in both academic and extracurricular fields.

A public address system was installed in the playground, which proved to be effective in developing a greater sense of unity in students.

[43] For the first time in the history of the school, study tours to Singapore and Malaysia were organised with part of the funds sponsored by the King's College Old Boy Association.

[44] In the transition year of 1997 in which the Handover took place, King's College was provided a chance to renew its oath to play a major role in the community of Hong Kong and China.

Dr. Simon Li Fook Sean, and old boy of King's College, received the Grand Bauhinia Medal (GMB) from the HKSAR Government in acknowledgement of his stupendous contributions to Hong Kong and China.

[45] Following the appointment of a new principal, Mr. Ho Yue Shun, in 1998, King's College has undergone massive changes, especially on the information technology front.

Professor Robert F. Curl, 1996 Nobel Laureate in Chemistry, visited King's College and met the senior students on 9 May 2002.

On 29 October 2003, Professor Jean-Marie Lehn, Nobel Laureate in Chemistry, visited King's College and met the senior students.

"[46] Built in 1926, the Bonham Road Campus is one of the oldest surviving pre-war government school buildings in Hong Kong.

The most impressive part of the school building is its circular entrance porch at the junction of Bonham Road and Western Street.

The porch is supported by granite coupled columns with Ionic Order capitals featuring volute brackets and Italian Renaissance style side openings.

Since then the orthodox structure has reserved its current façades of grey granite columns against a background of crimson bricks, arched corridors and cavernous garden, an image widely held by its students and the public as an epitome of the college.

[50] King's College's alumni include the "father of OLED" Ching W. Tang; the "father of rehabilitation" in Asia Sir Harry Fang; Hong Kong senior judge and politician Simon Li; Chief Executive Leung Chun Ying; Hong Kong media mogul George Ho; the first Chinese Commissioner of the Royal Hong Kong Police, Li Kwan Ha; the last Commissioner of the Royal Hong Kong Police Hui Ki On; industrialist and politician Sir Sze-yuen Chung; and the creator of Hang Seng Index Stanley Kwan.

Alumni noted for their work in academia include "father of OLED" Ching W. Tang; the former Vice-Chancellor of the Chinese University of Hong Kong Ma Lin; and American scientist and author Deborah Chung.

The Education Bureau's implementation of school-based management aimed to decentralize decision-making powers such as student learning and resource allocation to schools.

As a government school, the principal of King's College is appointed by the Education Bureau and is part of the civil service system.
