Priscilla Sitienei, a 90-year old Kenyan woman, who shares a class with six of her great-great grandchildren, explained she in school to "inspire children". Adorning the school uniform, as other students, gogo as she is fondly called, has learnt to write in English. She enrolled in the Leaders Vision Preparatory School, in the village of Ndalat five years ago, and was the town's midwife for last 65 years.
"I want to say to the children of the world, especially girls, that education will be your wealth," the nonagenarian said. Describing learning as an opportunity she did not have as a child, Sitienei told BBC her aim also include 'being able to read the Bible'.
Sitienei laments low enrolment of adults in school, a situation she tried to find a reason for by confronting the affected adults.
"They tell me they are too old," she says, "I tell them, 'Well I am at school and so should you.'
"I see children who are lost, children who are without fathers, just going round and round, hopeless. I want to inspire them to go to school."
The school headmaster David Kinyanjui believes Gogo, who boards at the village school, is an example to the rest of her class. He said he inititially rejected her, but changed his mind when he saw she was passionate.
"I'm very proud of her," the teacher says, adding that "Gogo has been a blessing to this school, she has been a motivator to all the pupils."
"She is doing well… considering her age I can say I have seen a big difference in this school since she came," he said.
