Changes to data collection/processing
In 2018, the Ministry of Education developed a new data series for the schooling workforce. This is based on a calendar year, rather than a point in time (single pay run) as occurs with the old measure (which was based on the first pay run in April) The new data series therefore includes a greater number of teachers.
The new data series covers a twelve month period with the start of the year being the first pay period that is fully within January.
The new schooling workforce data series includes composite schools in the secondary sector.

About this dataset
This data series presents demographic information on teachers in state and state integrated schools and covers a twelve month period with the start of the year being the first pay period that is fully within January.
Method of collection/Data provider
The size of the teaching workforce can be measured either as a headcount or in terms of full-time teacher equivalents (FTTE). FTTE data are only available from 2014 onwards - data from previous years are not comparable due to changes in definitions.
