The 2026 KCSE examination period has been marred by a significant disciplinary incident in Machakos County, where twelve students from Kitonyini High School were disqualified from sitting their remaining papers. According to reports, the students were found in possession of mobile phones within the examination center, an act strictly prohibited by the Kenya National Examinations Council (KNEC) to maintain the integrity of the national tests.

School authorities and examination officials confirmed the incident, noting that the discovery was made during routine security checks conducted before the start of the day's papers. The students were immediately barred from continuing with the examination, effectively ending their participation in this year's cycle. The incident has sparked concern among parents and education stakeholders regarding the enforcement of examination rules and the pressure students face during the final assessment period.

KNEC has maintained a zero-tolerance policy toward examination malpractice, with officials frequently warning that any candidate found with unauthorized materials, including electronic devices, faces immediate disqualification. The council has deployed security personnel and invigilators across the country to monitor the ongoing exams, which are critical for university and college placement.

This development comes amid a broader period of scrutiny for the education sector, which has recently faced challenges including school unrest and debates over the 2027 academic calendar. The Ministry of Education has yet to issue a formal statement on the specific disciplinary measures the students will face beyond the immediate disqualification from the current exams.

As the KCSE examinations continue nationwide, the incident serves as a stark reminder of the stringent measures in place to protect the credibility of the national certification process. Education experts are calling for increased vigilance and counseling for students to prevent such occurrences, which have long-term implications for the affected candidates' academic futures.
