The Kenya National Union of Teachers (KNUT) asks teachers to boycott the new curriculum and revert to the 8-4-4 curriculum.
KNUT Secretary General Wilson Sossion, accused the Education Cabinet Secretary George Magoha of being arrogant and intolerant.
Sossion says, teachers had not been well trained on it and that they will explore engaging in mass action to achieve their goals.
CS Magoha had earlier stated that the roll-out of the CBC was unstoppable and revealed that so far, 12 million books have been distributed to schools.
Speaking during the launch of a new curriculum policy, Magoha stated that the implementation of the new curriculum is his utmost priority.
He further downplayed critics of the curriculum including the Kenya National Union of Teachers saying it will benefit all students.
The new curriculum policy details how the ministry will ensure proper implementation of the new curriculum.
The policy further formalises the responsibilities of various actors involved directly and indirectly in the curriculum reform, development and implementation process.
