The Teachers Service Commission (TSC) has transferred 3,094 head teachers of primary and secondary schools following retirements.
In a statement on Tuesday, Chief Executive Officer Nancy Macharia said those transferred have until December 28 to hand over.
The CEO explained that the transfers followed the retirement of headteachers and principals who attained the mandatory age in the last three months.
"As a result, deputy heads who are qualified and have exemplary performance records have been promoted to headship positions and transferred accordingly," she said.
"Inevitably, some serving heads have also been transferred to take the positions that fell vacant. This is necessary to match performance and experience to the enrollment and level of the institutions."
Mrs Macharia directed the TSC's county directors to ensure a status report on the transitions is submitted to the staffing director by December 31.
"Any issues by individual heads that will arise from the transfers will be handled by the receiving county directors, who have been advised accordingly," said Mrs Macharia.
