Originally set up in 1929 as Ruthimitu Independent School, Dagoretti High School emerged as a response to the expulsion of African pupils from mission schools due to their support for the
Female genital mutilation rite of passage for
Kikuyu girls. However, the school faced opposition from both the missionaries and the colonial government, leading to its closure in the early 1930s. The persistence and determination of African leaders, notably
President Jomo Kenyatta, paved the way for the school’s reopening in 1939. Under the new management of the Kikuyu Karing’a School Association (KKSA), the institution was renamed Waithaka Independent School. Mr.
Eliud Mathu, a distinguished graduate of Makerere University College in Uganda, assumed the role of the first principal around 1942. Sadly, during the state of emergency in Kenya, the school was abruptly shut down in 1954 and repurposed as a detention camp for
Mau Mau prisoners. However, adversity only fuelled the school’s resolve to provide quality education. In 1959, - via the initiative of people such as the first
Member of Parliament for
Dagoretti Constituency Dr Njoroge Magana Mungai - the conversion of the detention camp back into a school began, with the aim of admitting its first batch of Form One students in January 1961. Construction delays led to a temporary arrangement, and the inaugural Form One students were accommodated at
Thika High School for one year. On 15 November 1961, a significant milestone was reached. The Dagoretti Locational Council, supported by the Kiambu District Education Officer, Mr. J. E. Cowley, proposed a name change for the school, and it officially became Dagoretti High School. Its doors finally opened to its first cohort of students in January 1962. A committee consisting of prominent individuals - including Mr. Eliud Njuguna Kuria, Mr. Tiras Waiyaki, Mr. Peter Kuria Ndwaru, and Mr. Geoffrey Kiuna - was entrusted with the responsibility of overseeing the school’s administration. Their first meeting on 28 March 1962 marked the beginning of a collaborative effort to shape the future of the institution. The first Headmaster of the school was Mr N. C. Bhatt. A significant turning point arrived on 21 September 1963 when Dagoretti High School was officially inaugurated by Mr. Kenneth Matiba, the then Permanent Secretary for Education. This auspicious occasion symbolised the unwavering commitment to educational excellence and the anticipation of a bright future for generations of students to come. ==Extracurricular activities==
