Parents and guardians on Thursday rushed to buy books and uniforms ahead of school reopening next week.
The school reopening comes at a time when the country is experiencing a rise in the price of essential commodities.
Education Cabinet Secretary Ezekiel Machogu has warned school heads against "attempting" to introduce illegal levies in schools.
He said they must stick to the Ministry of Education-approved fee structures to ease the burden on parents who are reeling from the effects of hard economic times.
The CS said the government will "swiftly and firmly" respond to any reports of headteachers charging unapproved fees.
