Ganze Boys Secondary School on Thursday admitted a 74-year-old man in Form One.
His two sons – one in Form Two and the other in Form Four - also study at the same school.
Kazungu Humadi Kadenge from Kilifi County scored 134 marks in the 2016 Kenya Certificate of Primary Education (KCPE) examinations.
He sat for the exams at Ganze Primary School.
Kadenge says he opted to go back to school to avoid being looked down upon as illiterate and to escape being branded a sorcerer.
He reportedly dropped out of school in Standard Four 50 years ago, but insisted on registering for 2016 KCPE exams.
“I need to be close to my children so that I can monitor them and observe if there is anything that can make them drop out of school,” he told the Standard.
Kadenge says his wife was against him going back to class.
“I told my wife that I wanted to go back to school and that God would open ways for those still in school to finish.”
He was involved in an accident which left him with a wounded leg, forcing him to quit employment at the Kenya Power and Lighting Company in 1990.
He then came up with an initiative to construct a nursery school in the area to benefit children.
“In my efforts to get support to construct my nursery school, I met donors from one non-government organisation who agreed to put up two classrooms. I handed over the school to the Ministry of Education and this is when the management said it would be difficult for me to lead the school because I was illiterate,” Kadenge told the Standard.
He says his dream is to head the Ethics and Anti-Corruption Commission (EACC) to fight corruption in the country.
