Education CS Ezekiel Machogu now says some school heads lied about the mean scores achieved in the 2022 KCSE.
Machogu said the ministry singled out such schools saying the teachers wanted to give a wrong impression.
“There’s a school in my sub-county where the principal lied on their notice board that they had achieved a mean score of 7 points yet they had 4 points,” Machogu said.
He was speaking when he appeared before the National Assembly education committee.
Machogu said the principals who faked results even posted them on social media.
“We are even aware that there’s a principal in Kakamega who did the same so what was in the media was not real compared to the truth from the exam body,” he added.
This hearing comes in a progressive probe by MPs over alleged cheating in the exams.
The team led by Education committee chair Julius Melly was split into two teams during the probe.
"We had schools which moved from a mean grade of 6 to 10. As a committee, we have the responsibility to find out what was it that happened," Melly said.
Further, the lawmakers will also probe how the issues raised on examiners' demotivation could have affected exam results.
"If an examiner is not motivated would his demotivated attitude affect results and the relationship between centre managers and examiners?"
The committee invited the public to submit their views either orally or written from March 20 to March 27 in 11 counties.
Last week the team concluded the public hearing.
