Primary education in Kenya begins at the age of 5 to 7 after completion of a year of kindergarten commonly known as Nursery School or pre-unit. The first class or year of primary school is known as Standard 1, the final year as Standard 8 and primary school children are known as pupils. The school year at both primary and secondary levels, begins in January and ends in November. Students get 3 school vacations in April, August and December.
At the end of the school year students advance to the next grade.Since repetition was banned students still progress to the next grade even though they fail their examinations. Most primary schools are day schools with pupils living at home. Fewer schools at primary level are boarding schools compared to secondary schools. All public primary school pupils sit for the Kenya Certificate of Primary Education examination at the end of the school year in Standard eight.
In January 2003 President Mwai Kibaki re-introduced free primary education which previously existed before the mid 80s when the government adopted cost sharing measures that led to a minor level of school fees charged by primary schools for text books, PTA, and extra curricular activities. Since 2003, education in public schools became free and compulsory ( Kenya Constitution,Article 53, 2010). On learning that primary education had once again become free in Kenya, Kimani Maruge, an uneducated farmer and the world's oldest person to enroll in primary school joined Kapkenduiywo primary school in Eldoret at the age of 84. He was elected head boy at the age of 86 in 2005.
