Education officers and stakeholders are already assembled at the Kenya National Examinations Council headquarters on Dennis Pritt Road for the release the 2018 Form 4 national exam results.
Education Cabinet Secretary Amina Mohamed will preside over the ceremony after meeting and briefing President Kenyatta at State House in Nairobi.
More than 600,000 candidates wrote the tests that saw one of the strictest supervision and invigilation in Kenya's history.
However, Ms Mohamed is unlikely to rank schools, candidates and counties even after President Kenyatta assented to a bill that restored the old system.
The Education ministry is yet to formulate rules that would operationalise ranking as provided for in the new law passed in 2016.
Ranking was banned in 2014 after it emerged that the practice created unnecessary competition among schools, resulting in cheating.
A total of 664,585 candidates sat for the exams that was done between November 5 and November 28.
The ministry had promised to release the results before Christmas. Last year, the results were released on December 20.
This is the 29th KCSE examination to be conducted since the introduction of 8-4-4 system of education.
