Nyanchwa Boys High School is situated 1.5km from Kisii CBD behind Gusii Stadium along Nyanchwa Road. The school rests on approximately 7 acres land on the slopes of Nyanchwa hills overlooking kisii town  giving a panoramic view of the town. it borders lower Nyanchwa that is mostly a  commercial residence estate, Nyanchwa public primary on the left , upper Nyanchwa community and Nyanchwa Girls  and south Kenya conference(SKC) headquarters on the right .    


Nyanchwa started as a Primary School in1918 and its primary objective was to teach the young and old how to read and write. The school was commonly known as Rirondo which means “make shift” building. No certificate was offered after this course. Pastor Paul Nyamweya was in charge assisted by Senior Chief Musa Nyandusi.


Formal education was begun in early 1930s which was then supervised and managed by Pastors from the Seventh Day Adventist Church. Pastor Stanley  Nyachieo was the Education director. In 1948, Pastor Webster was in charge and the school offered intermediate exams standard seven then was equivalent to the current form one and competitive Examination (KAPE) was offered.


The secondary school was started in 1965 as a Harambee school’ with boarding facilities located at the current Nyanchwa Adventist School. In 1974, the school was taken over by the Government. Since then, the school has been headed by several head teachers among them the late Mr. Hezekiah Mobisa, the late Mr.Joel Amenya, the late Mr. Gideon Machoka, Mr John Abai, Hon Joel Onyancha, the late Mrs. Bathsheba Nyambane, Mr. Naphtal Nyang’iti, Mr. Timothy Atuti Oboso and Nelson Omwenga.(current Principal),bringing a total of Principals who have served to 9.




For all those years 1974-2010 the Institution has been operating as a boarding mixed secondary school.

The School had an A-Level segment and it used to offer one stream of science and another one stream of Arts.




Following the challenges facing Mixed Secondary Schools among them Boy-Girl relationships and high levels of indiscipline which have caused poor results, the stake holders recommended the split of the school into two in the year 2008; Nyanchwa Girls and Nyanchwa Boys. The separation was officially done in October, 2010 with Mrs. Norah Nyakundi  Osano as the Principal of the Girls’ School deputized by Mrs.Deborah Osoro. The Boys’ Section was headed by Mr. Timothy Atuti Oboso assisted by Mr.Hezron Nyasani as the Deputy Principal.



These changes have been welcomed by the community and a lot of improvement is expected in terms of discipline and performance in National Examinations.
