The Sustainable School Leadership project studied how England, Scotland and Northern Ireland recruit, train and retain school leaders. In Northern Ireland the research combined an analysis of public workforce statistics, a survey of 240 school leaders, and in-depth interviews with 37 leaders across two contrasting localities — Town-Rural and Coast. The results show leadership enmeshed with complex community identities, and a profession navigating political instability and prolonged industrial action.
Northern Ireland is the smallest of the three systems studied, with just over 1,000 schools. Many sit in urban centres including Belfast, but large rural areas are served by small schools: in 2022, 193 of 440 rural primaries had fewer than 105 pupils.
Given its size, the system is remarkably complex — reflecting historic sectarian divides, more recent efforts to build Integrated and Irish-medium sectors, and academic selection at age 11. Many schools now educate a mix of children from different religious communities, and many families identify with none, but school choices are still commonly influenced by community and cultural difference.

Leaders were asked to select the three to five factors they found most draining, and the three to five they found most sustaining. Poor work–life balance came top in Northern Ireland, followed by the weight of leadership, operational and administrative burdens, and staffing issues. Operational issues stand out as particularly challenging here, with many respondents describing a "broken system".
Despite this, leaders were clear that they are sustained by working with children and young people and by their relationships with colleagues and communities. Community engagement and relationships with governors and parents feature far more strongly in Northern Ireland than elsewhere — 24.8%, against 14.7% in Scotland and 13.8% in England.
Asked which description best fitted their own experience of the last twelve months, 42.7% of principals in Northern Ireland said they were sometimes or mostly thriving — close to England's 44.2% and well above Scotland's 34.8%. The share describing themselves as sometimes or mostly sinking, 19.1%, is the lowest of the three nations.
That is the more encouraging half of the picture. The other half is that nearly one in five leaders is still on the sinking side of the line, and the largest single group in every nation is simply surviving.
The leadership workforce has aged clearly over the past decade. Among principals the share aged under 40 has fallen since 2011/12, while 50–54 has grown into the single largest band. The average age of principals rose from 49 in 2010 to 50 in 2024.
Vice-principals show a similar pattern from a slightly younger base, with the under-40 share also declining. Taken together the figures suggest a pipeline heavily concentrated in mid- to late-career stages, with limited growth in younger leaders coming through.
Around 30–35% of advertised leadership posts go unfilled each year. Fill rates for principal posts in nursery, primary and preparatory schools have swung sharply — as low as 48% in 2020 (when recruitment was paused during the lockdowns), recovering to 68.8% by 2024. Vice-principal vacancies are more volatile still.
Churn compounds the problem. Over the past decade annual leaver rates have run between 7.4% and 10.4%, while joiner rates have sometimes been lower. In 2024/25, 9.2% of principals and vice-principals left against 7.8% joining.
Schools and leaders in Northern Ireland are distinctively embedded in their communities. In Northern Ireland you are always principal of your school; everyone knows who you are. Leaders occupy social roles in communities they often grew up in or returned to, and the pastoral orientation of the role is lived reality rather than rhetoric. At a time when the leadership of care appears far more central everywhere, that commitment is valuable.
Against it sit political and systemic fragility — prolonged Assembly suspensions, years of Action Short of Strike, suspended inspections and funding shortfalls — and a workforce that is ageing without a clear development pathway behind it. The question is not whether Northern Ireland has dedicated leaders, but whether the system can sustain them and keep attracting the next generation.
12.2% of leaders had always wanted the job. 64.2% say the aspiration emerged during their career — the highest of the three nations — and 23.7% describe the route as accidental.
Among leaders not yet in headship, just 24% say "yes, perhaps" or "yes, definitely" — against 33.1% in England and 39% in Scotland.
Women are 77% of teachers but 61% of principals, falling to 48.9% in post-primary. No official workforce statistics on ethnicity are published; representation in leadership appears negligible.
Operational burden, lack of system support and the weight of leadership are the distinctive Northern Irish drains — all of them system-level levers rather than individual resilience problems.
