Two KCSE candidates who were found with mobile phones in school will be taken to court on Monday.
This brings to six, the number of cases of exam irregularities that have been reported and taken to court since the exams kicked off last Monday.
One of the suspects will be charged in Nairobi while the other student will be arraigned in Wajir.
KNEC chairman George Magoha said in a statement on Sunday the other four cases involve examination centre managers and officials.
The Kenya National Examination Council boss said the accused attempted to open exam papers prior to their stipulated time.
"Fortunately, all the cases were discovered and nipped in the bud before the affected examination questions could be relayed to candidates," Magoha said.
No exam irregularities were reported in last year’s national exams which were the first to be conducted under revised strict regulations.
The rules were introduced by Education CS Fred Matiang'i to curb increased cheating in the exams orchestrated by teachers, police and Knec officials.
In 2015, massive irregularities saw the results of about 2,709 primary and 5,100 secondary school candidates cancelled.
Prof Magoha said those to appear in court on Monday include a female candidate at Our Lady of Mercy Girls secondary school in Shauri Moyo, Nairobi.
She was found with a mobile phone at the school.
The second culprit is a candidate at Furqan Integrated in Wajir county who was also found with a mobile phone.
The latter had used the gadget to send purported examination questions to another candidate at a school in Nairobi.
Magoha said four other culprits had already been charged with crimes related to the exams.
Among them is a student at Langata Private Centre who was arraigned last Friday for being in possession of unauthorised examination material.
"He was released on bond," Magoha said.
Others are the school principal of St Theresa Bikeke secondary school in Trans Nzoia and the school’s chemistry teacher David Wafula.
They were taken to court last Thursday.
This was after Wafula sent some chemistry questions to a principal in Elgeyo Marakwet County having received them from a Mr Jerry Ndikolo of Sawagongo secondary school in Siaya.
Save for the above incidents, the Knec boss noted that the examinations have been going on smoothly despite the ongoing rains in some parts of the country.
The rains have rendered some regions impassable leading to a delay of deliver of exams to some schools.
"KNEC, security officials and other stakeholders have conducted the KCSE examinations with a high level of professionalism."
Magoha said examination officials will remain vigilant in implementing measures to ensure the exams are conducted under the highest levels of integrity going into the second week of the exercise.
"Firm action will be taken against schools, principals, candidates and any other person found to engage in examination irregularities of any kind," Magoha said.
The KCSE exams will be concluded on November 29.
