The current in-school management structures were agreed and implemented in the late 1990s as a result of the PCW national pay agreement.
The allowance payable to principal teachers employed by the managerial authorities of primary schools is an eleven point scale. The allowance for Post Primary Principals is a seventeen point scale. This allowance is paid in addition to the teachers' basic salary. A basis for the difference in the length of the scales is the fact that primary schools in general are smaller than post primary schools. At this time there are no plans to review theses pay scales.
