The Door of Hope
The story of Kambui begins in August 1902 when American Baptist missionaries William Porter Knapp and his wife Myrtle Isabelle Knapp of the Gospel Missionary Society (GMS) established a permanent headquarters at the Kambui Hills.
In November 1902, the first mud-walled, grass-thatched chapel was dedicated and named "The Door of Hope". From the very beginning, the mission taught children in the morning and adults in the evening, weaving education and faith together in every aspect of daily life.
A mud-walled chapel named "The Door of Hope" — from these humble beginnings, one of Kenya's most distinguished schools was born.
1902 — The Beginning
The Kambui Hills — Where It All Began
Nestled in the green hills of Githunguri in Kiambu County, the Kambui grounds have been a place of learning, faith and community since 1902. The same land where a missionary's wife first opened a literacy class now hosts one of Kenya's most respected girls' boarding schools.

Educating the Educators
In 1914, the institution officially began admitting girls and young women. Over the following decades it evolved into a vital Teachers' Training College (TTC), producing P1 teachers who shaped classrooms across Kenya.
In 1945, the Gospel Missionary Society merged with the Church of Scotland Mission (CSM), laying the groundwork for what officially became the Presbyterian Church of East Africa (PCEA) in 1956 — the sponsoring body that guides the school to this day.
The teachers trained at Kambui carried its spirit into classrooms across Kenya — making this campus one of the quiet engines behind the nation's early education system.

Training the Teachers Who Built Kenya
Hundreds of teachers trained on this ground went on to build Kenya's education system from the ground up. The P3 and P1 certificates earned at Kambui TTC opened the doors of classrooms across every corner of the country.

Mama Lucy — A Principal Who Made History
During the late 1950s, Lucy Kibaki — later Kenya's beloved First Lady — was transferred to Kambui TTC as a tutor. She rose to become the institution's Principal, leaving a profound and lasting mark on the school.
Under her guidance she moulded future national leaders including Beth Mugo, who studied at Kambui from 1956 to 1957. For decades, students gathered under a sacred Mugumo (fig) tree for evening prayers — a tradition woven into the identity of Kambui.
"Once students entered the school gates, they were not allowed to leave until the end of term — a discipline that built focus and forged strong academic character."

A Legacy Written in the Lives She Shaped
The influence of Lucy Kibaki on this school cannot be overstated. The discipline, the spiritual character and the academic seriousness she instilled became the defining traits of Kambui Girls — traits that live on in every student who passes through these gates today.
A New Chapter — Secondary School
As the government restructured regional teacher training colleges, the Kambui facility shifted its focus exclusively to secondary education. The formal secondary school was registered, marking the beginning of a new era while honouring everything that had come before.
The school balanced its strict Presbyterian guidelines with local traditions. The Mugumo tree prayers continued. The discipline code remained firm. And the academic standards set by Mama Lucy defined the institution's character for decades.

A School That Stood for Something
From day one as a secondary school, Kambui Girls set itself apart. The combination of rigorous academics, Christian values and strict discipline created an environment where girls were not just taught — they were transformed. The school's reputation spread quickly across Kiambu County and beyond.
Embracing the 8-4-4 Curriculum
In 1989, Kenya introduced the national 8-4-4 curriculum. Kambui Girls adapted swiftly — retooling teaching methods and subject offerings. KCSE results year after year confirmed the school's commitment to quality had never wavered.
Graduates continued to proceed to universities within Kenya and abroad, carrying the Kambui name with pride into every profession and every corner of the country.

Adapting Without Losing Identity
Every national curriculum change has been met at Kambui with the same confidence and readiness. The school's identity — built on faith, discipline and academic excellence — has never depended on which curriculum it follows. It depends on the people who teach and the girls who learn within these walls.
