The Ministry of Education has postponed the National Steering Committee's curriculum review meeting that had been set for Thursday.
The postponement came a day after Education Cabinet Secretary Amina Mohamed announced that the curriculum will not be rolled out in January as had been planned.
The fate of the national conference on the curriculum review also hangs in the balance.
A statement from the ministry said the new date, of the review meeting that was to take place at the Kenya Institute of Curriculum Development (KICD), will be communicated to members.
"Our sincere apologies for any inconvenience this may cause. We thank you for your continued support," the ministry told committee members.
Members of the steering committee team are drawn from religious organisations, universities, secondary schools, civil society organisations and teachers' unions.
The team is tasked with guiding policies for the different levels of education, on matters development and the implementation and assessment of the curriculum for education and training.
Members also coordinate the development of budgets and the implementation framework for the competence-based curriculum.
The new curriculum was to begin with pupils from nursery to Standard Three following two years of piloting.
Education stakeholders stakeholders raised several concerns on the 2-6-3-3-3 system that was to replace the 8-4-4 system of education from next year.
Before the Senate Education committee on Tuesday, CS Mohamed explained the need to develop infrastructure and sufficiently train teachers.
Next week, a team of external evaluators is expected to present its report on the new curriculum to Ms Mohamed.
