context: KCPE is a summary of the Kenya Certificate of Primary Education, a certificate award for students after graduating for eight years in primary education in Kenya. Its examinations are administered by the Kenya National Examination Council (KNEC), the government body responsible for administering examinations in Kenya, under the Ministry of Education. The unit also manages and makes changes to the Kenya Higher Education Certificate (KCSE), a certificate award for students after completing secondary school. KCSE and KCPE certificates were introduced in Kenya at the time of 1985 an 8.4.4 education system was established. The maximum mark is 500 but that is usually not possible due to symmetry (given some marks in each subject). This test is used to determine which high school each student will join.
