Earlier directory summary
Lenana Sch is in Nairobi County (Dagoretti Constituency).
Lenana Sch is a boys day secondary school.
Lenana School is a high school in Nairobi, Kenya.
It was formed in 1949 by colonial governor Philip Euen Mitchell in 1949, known then as the Duke of York School. The first students were briefly housed at the then British colonial Governor’s House which is the current State House as they waited for the school’s completion. The founding principal/headmaster was R.H. James.
Originally the school was reserved for white students only within the racial system of colonial Kenya, but after independence in 1963 there were gradual changes that led to the first few black and Asian students being admitted in the mid 1960s.
The school was renamed Lenana School in 1969 after the legendary Laibon Lenana who was the central human figure in the Maasai religious system and ruled around the end of the 19th century through to the early 20th century. The first Kenyan headmaster (principal) of the school was Mr. James Kamunge.
Lenana School currently has 1200 students. In 2006, it was ranked 26th best high school in Kenya based on Kenya Certificate of Secondary Education results.Through the 1980s and into the 21st century, Lenana School has maintained high academic standards ranking in the top 10 and top 20 respectively for many years in the 1980s. The current School Principal is Mr. William Mwangi who is deputised by Mr. Silas Wandera.
