Matiang'i will be accompanied by education officials during the said exercise.
Earlier this month, Matiang'i had asked all parties involved in the 2016 KCSE to complete the job before Christmas celebrations.
Matiang'i surprised the country when he released KCPE results much earlier than expected.
He said that parents and students needed time to prepare for the next steps after the release of the results.
The CS, during the launch of form one selection at the Kenya Institute of Curriculum Development, urged the examiners to work round the clock to ensure the exams are released within schedule.
