There were more vacancies in November 2024 than in the previous year, with 1,742 teacher vacancies at the end of the academic year 2023/24, 1,382 (79.3%) of which had been filled by November 2024 (when the survey was carried out).
The average number of days lost per teacher due to sickness, in all schools in 2024/25 was 9.4. This represents a decrease of 0.3 days from 2023/24.
Teacher substitution costs have increased from £85 million in 2023/24 to £112.1 million in 2024/25.
The number of substitution days worked by Prematurely Retired Teachers has fallen from 1,525 days in 2023/24 to 1,403 days in 2024/25. This represents 0.2% of the total days worked, compared to 2.2% in 2015/16.
The purpose of this statistical bulletin is to provide analysis of the latest annual data collections relating to teacher vacancies, teacher sickness absence (excluding voluntary grammar) and teacher substitution (excluding voluntary grammar) in grant-aided schools in 2024/25.
The information collected throughout this process is used by policy branches within the Department of Education to inform education workforce policy. The data are also used to respond to Assembly questions.
All figures referred to are included in the main body of the text. All tables can be downloaded as excel or csv files in the section List of tables.
Figure 1 shows the total number of teacher vacancies at the end of 2023/24 and the proportions which were filled or unfilled by November 2024. There were 1,742 teacher vacancies at the end of the academic year 2023/24, 1,382 (79.3%) of which had been filled by November 2024. This compares with 1,046 of 1,291 (81%) vacancies filled the year previous.
There was a larger proportion of unfilled vacancies in nursery, primary and preparatory departments of grammar schools than in post primary schools.
The highest proportion of unfilled vacancies was in Special schools, with 28.1% of vacancies unfilled by November 2024. Tables 1 and 2 outline the teacher vacancy data in more detail. These can be found in the final section of the publication.
The level of sickness absence during 2020/21 may have been affected by school closures due to COVID-19 and because COVID-19 related absences were being recorded separately and not included within sickness absence on the Teachers’ Pay and Pensions System for most of the year. Figures for 2021/22 do include sickness absences due to COVID-19 but do not include absences due to the 10 day isolation period for COVID-19 or any other COVID-19 related absence. See note 12 in notes to readers.
Figure 4 shows the percentage of days lost due to short and long term sickness from 2020/21 to 2024/25. In 2020/21, when sickness absences were affected by school closures and by COVID-19 absences being recorded separately, 80.9% of sickness absences were long term (more than 20 days) while only 10.9% were medium term (5 to 6 days) and 8.2% were short term (less than 5 days).
Between 2022/23 and 2024/25 sickness absences due to short (20.9% in both 2022/23 and 2024/25), medium (13.1% in 2022/23 and 13.3% in 2024/25) and long term sickness (66% in 2022/23 and 65.8% in 2024/25) have remained relatively constant. This information can be found in Table 3 which can be found in the final section.
Figure 5 shows the teacher substitution costs for each year from 2015/16 to 2024/25. Overall, teacher substitution costs have increased from 2015/16 to 2024/25, from £67.3 million to £112.1 million. Teacher substitution costs also increased from £85 million in 2023/24 to 112.1 million in 2024/25. This information is given in Tables 6 and 7 and a breakdown by school type is given in Table 8. These tables can be found in the final section of the publication.
Table 9 gives a breakdown of the cost of substitution cover by reason. The figures up to 2022/23 are based on the absence reason recorded for the permanent teacher, however from 2023/24 onwards the data is based on the absence reason recorded for the supply teacher, therefore, the 2023/24 and 2024/25 figures should not be compared with previous years. In 2024/25 the highest cost of substitution was vacant posts at a cost of £38.1 million, followed by sickness at £22.5 million and maternity/adoption/paternity at £16.6 million. This can be found in the final section of the publication.
Figure 7 shows the proportion of substitution days worked by Prematurely Retired Teachers for each year from 2015/16 to 2024/25. The number of substitution days worked by prematurely retired teachers has fallen from 10,080 in 2015/16 to 1,403 in 2024/25, which represents 0.2% of the total days worked, compared to 2.2% in 2015/16. This information is presented in Table 11 and 12. These can be found in the final section of the publication.
The reduction in substitute cover provided by prematurely retired
teachers may be due to changes in pay for substitute teachers. In 2011,
the Department issued guidance to schools on rates of pay for
prematurely retired teachers. The link below gives the circular issued
to schools detailing the new rate of pay effective from 1 September 2011
for prematurely retired teachers who are re-employed.

Table 13 shows the average daily and hourly substitute cover rates. The daily cost for controlled and maintained schools has increased by £33.07 and £35.79 from £155.46 and £150.26 in 2020/21 to £188.53 and £186.05 in 2024/25. The daily cost for special controlled and maintained schools has increased by £15.53 and decreased by £3.96 from £168.46 and £170.91 in 2020/21 to £183.99 and £166.95 in 2024/25.

The Department committed to publish key figures on the Management of Substitution Cover for Teachers on an annual basis by 30 June each year, beginning in 2012. This commitment was given in DFP’s Memorandum on the 2nd Report from the Public Accounts Committee Session 2010/11 – The Management of Substitution Cover for Teachers: Follow up Report 25 Jan 2011.

The teacher sickness absence data is extracted from the computerised teachers’ payroll system.
Teacher sickness absences are given for the financial year 1 April 2024 to 31 March 2025.
The number of all permanent teachers used is an average number of teachers who have worked in schools from 1 April 2024 to 31 March 2025.
The following types of teacher are included in the teacher
sickness absence:
Excluded from all figures are teachers at voluntary grammar schools and their preparatory departments as this information is not available from the teachers’ payroll system. Teachers in the preparatory departments of controlled grammar schools are included in the grammar figures.
The numbers are based on a headcount, not full-time equivalent.
For 2020/21 figures exclude any sickness due to COVID-19. From 11 February 2021 the guidance to schools on recording COVID-19 absences was updated to provide that for a teacher with confirmed COVID-19, absence after the first 10 days should be recorded as a sickness absence rather than COVID-19 absence and for 2022/23 onwards figures include all sickness absences due to COVID-19.
Teacher substitution data is extracted from the computerised teachers’ payroll system. Substitution costs are calculated on the teachers’ payroll system from service processed through the Northern Ireland Supply Teachers’ Register (NISTR).
Figures are based on financial years i.e. 1 April 2024 – 31 March 2025.
Figures include peripatetic teachers.
All permanent and temporary payroll (substitution) costs exclude employers’ national insurance and superannuation costs.
All substitution costs relate to temporary payroll only.
Total teaching days are calculated as the average headcount of teachers multiplied by the total number of teaching days in a year, 195.
Substitute days booked from a COVID-19 budget from 2020/21 onwards are not included in the substitute days total as these were booked using dummy schools so a breakdown of them could not be provided for those years. However, these have been included in the substitution costs under a COVID-19 category so the cost is separately identified.
A Voluntary school means a grant-aided school other than a controlled school or a grant‐maintained integrated school:
