The Teachers Service Commission (TSC) has suspended new appointments to school management positions as implementation of the Sh54 billion salary deal begins.
Moving teachers to senior management positions will have a huge financial implication on the new pay deal.
The collective bargaining agreement (CBA) signed between the Government and teachers' unions favours those in higher job groups, including principals, their deputies and curriculum support staff.
The new salaries will benefit all 305,000 teachers.
In a circular to county directors of education, TSC Chief Executive Nancy Macharia said the move was in line with the pending implementation of the 2017-2021 CBA effective July 1, 2017.
She directed the immediate suspension of promotions to key senior positions pending fresh guidelines.
The salary deal shows two payment plans for classroom teachers and staff in management positions.
Implementation will be done in two phases for staff in lower job groups H, J and K, and in four phases for those in higher job groups L to R.
The new grading system that ranges from B5 to D5, implemented for those earning between Sh21,757 and Sh43,694, will be done in two phases.
Teachers in higher groups C3 to D5, and who earn between Sh43,154 and Sh157,656, will get their increment in four phases.
Sources at TSC told The Standard concerns about the financial implication prompted the freeze on appointments of new managers.
Macharia said the decision was also informed by the implementation of the job evaluation report for the teaching service.
"One of the major changes adopted by the commission following the job evaluation is the substantive appointment of institutional administrators and curriculum support officers."
Data on vacant positions will be submitted to the TSC secretary, who will issue appointment guidelines.
