Busia Senator Okiya Omtatah has demanded that the Kenya National Examinations Council (KNEC) immediately regrade the 2025 Kenya Certificate of Secondary Education (KCSE) results, citing unfair and discriminatory treatment of Kenya Sign Language (KSL). He claims KSL was inconsistently graded, negatively impacting candidates.

• KSL was treated as a compulsory language for hearing-impaired candidates but excluded from the final aggregate score for hearing candidates who took it as a technical subject.
• Senator Omtatah argues this policy shift was implemented without prior notice or public participation, disadvantaging students who had studied KSL since Form Two expecting it to count towards their final grade.
• He has given KNEC seven days to provide data on affected candidates, recompute results, issue a clear policy directive for future grading, and temporarily suspend 2026 KCSE registration, threatening legal action if ignored.
