Education Cabinet Secretary Prof George Magoha has a reputation for mincing no words when addressing sensitive issues. 

Is there a story unfolding in your community? Let Hivisasa know

He doesn't care whether his words, seen by many as undiplomatic, offend the sensibilities of his audience or not. 

On Thursday, the tough-talking CS took aim at those opposed to the competency-based curriculum that the government is keen on rolling out. 

He used swear words that captured his frustrations with those railing against the curriculum.

"Who the hell do you think you are? What the hell do you think you are doing? Did we spend so much time thinking about nothing and talking about nothing? 

Have you measured the thickness of my skin? When I was at the University of Nairobi, you will find that my skin became thicker than that of a hippopotamus, so stop wasting your time," Prof Magoha fired. 

The Education CS maintained that the government would go ahead with plans of rolling out the new curriculum despite opposition from some quarters.

He called on those with a better plan to share it with him and argued that the new curriculum will go a long way in addressing the mediocrity in the education sector.

The Kenya National Union of Teachers (KNUT) has opposed the curriculum, saying that stakeholders were not consulted.
