Why teacher mental health support matters
Walk into most secondary staffrooms in June and you can feel it. The conversations are shorter. The laughter is thinner. Teachers who used to stay back for a chat are now packing up the second the bell goes, and a meaningful proportion of the staff are quietly working out whether they will still be in the classroom in September.
This is not a new story. The Education Support charity's Teacher Wellbeing Index has been running since 2017, and the headline numbers have been difficult reading for most of that time. The 2024 edition, the eighth, found that 78% of school staff described themselves as stressed, with the figure climbing to 84% for senior leaders. Around a third had considered leaving the profession in the previous year. The reasons cluster around workload, accountability pressure, and the volume of pastoral work falling on classroom teachers who are not trained mental health professionals.
This article is not about resilience training or mindfulness apps. Those have their place, but the evidence suggests that the most useful interventions sit at the level of how schools are organised, not at the level of individual coping strategies. The aim here is to summarise what we know about teacher wellbeing, why it tends to matter for pupils, and what a head of department, pastoral lead, or member of SLT can actually do about it without waiting for the system to change.
What the data actually says
The Education Support Wellbeing Index is the most consistent UK source on this. Across its recent reports, a few patterns show up repeatedly.
Workload is among the most cited drivers of poor mental health, named by roughly three quarters of teachers who reported stress. Volume of work matters, but so does the nature of it. Tasks that feel meaningful (planning a lesson, marking a piece of work that will get useful feedback to a student) tend to be tolerated even when they push hours up. Tasks that feel performative (filling in a tracker that nobody reads, writing the same target three different ways for three different documents) seem to corrode morale faster.
Accountability culture comes up second. Ofsted inspections, performance management cycles, and data deep dives all add a layer of anticipatory anxiety that sits on top of the day job. The Index has tracked this carefully since the introduction of the current inspection framework, and reports of inspection-related stress remain high among heads in particular.
The third pattern is pastoral overload. Teachers consistently report taking on a growing share of mental health support for students, often without training, without time built into the timetable, and without a clear referral path when a case sits beyond what a non-specialist can reasonably handle. This is sometimes called the "fourth-emergency-service" effect, and it tends to be heaviest on form tutors and pastoral leads.

The link between staff wellbeing and pupil outcomes
There is a fair argument that staff wellbeing matters on its own terms. Teachers are people, and people deserve to work in jobs that do not corrode them. That said, the link to pupil outcomes is worth taking seriously, because it tends to be the argument that lands with budget holders.
The most cited evidence in this space comes from a series of studies linking teacher emotional exhaustion to lower pupil attainment, particularly in literacy and numeracy at primary level. The mechanism is not mysterious. Exhausted teachers plan less ambitiously, mark less carefully, and have shorter fuses when classroom behaviour wobbles. A 2021 study by Madigan and Kim, looking across decades of teacher-burnout research, found a small but consistent negative relationship between teacher burnout and student achievement, and a larger one with student motivation.
Staff turnover also acts as a second-order drag on outcomes. When teachers leave mid-year, or when departments cycle through ECTs faster than they can be mentored properly, the curriculum loses continuity. Disadvantaged pupils tend to be hit hardest, because their schools are more likely to be the ones with high turnover in the first place.
None of this means that improving teacher wellbeing automatically improves results. Outcomes depend on dozens of overlapping factors. The honest position is that staff wellbeing is one of several variables that probably matters more than the system tends to acknowledge.
If you are making the case to a governing body or trust board, the language that tends to land is retention plus outcomes, not wellbeing on its own. A teacher who leaves in October because they are burnt out costs the school several thousand pounds in cover, recruitment, and induction. The wellbeing case and the financial case tend to point the same way.
The limits of individual resilience interventions
A lot of school wellbeing strategies focus on what individual teachers can do for themselves. Mindfulness apps. Wellbeing webinars. Resilience training delivered in twilight sessions on a Wednesday after a full day of teaching. The intention is good. The evidence is mixed at best.
The core problem is that most of these interventions treat the symptom rather than the cause. If a teacher is stressed because they are marking until midnight three nights a week, telling them to do a guided breathing exercise is a kind of category error. It is not that breathing exercises are bad. It is that they do not address the marking.
There is a more uncomfortable version of this too. When a school's wellbeing strategy consists mainly of resilience training, it can quietly shift the responsibility for staff mental health from the institution to the individual. This is sometimes called the "resilience trap" in the occupational health literature, and staff tend to notice it quickly.
The more honest version is to acknowledge that some drivers of poor staff wellbeing are structural and need to be addressed at the level of the school or the system. That is harder. It is also where the bigger gains tend to be.
Structural levers that actually move the needle
If individual resilience is the wrong place to focus, the question becomes: What are the structural changes that schools can make? Here is a short list of the levers that show up consistently in the research and in case studies of schools that have meaningfully improved staff wellbeing.
Cut low-value workload first
Audit the work staff actually do across a fortnight. Look for tasks that consume time but produce little for pupils or teachers (duplicate trackers, over-detailed lesson plan templates, performative marking policies). The Department for Education's Workload Reduction Toolkit gives a usable starting point. Cutting two hours of low-value work a week is more powerful than adding a wellbeing webinar.
Protect non-contact time
PPA and directed time should be genuinely usable. Stacking back-to-back meetings during PPA, or treating it as a flexible reservoir for cover, signals that the time is not really protected. The schools that tend to retain staff better are the ones that ringfence this time visibly.
Build sensible marking policies
EEF guidance is clear that the quality of feedback matters far more than the quantity or the colour of the pen. Whole-class feedback, codes-based marking, and live marking all do as much as triple-coloured deep marking for a fraction of the time cost. A revised policy can hand back two to four hours per teacher per week, depending on the subject.
Make pastoral referral pathways real
Form tutors and class teachers should not be the de facto mental health service. A documented referral pathway (to a DSL, school counsellor, mental health support team, or CAMHS depending on the case) lowers the load on classroom staff and tends to produce better outcomes for the students involved as well.
Treat ECT and middle leader support as serious
ECTs and middle leaders are the two groups that tend to leave first when wellbeing slips. Properly resourced mentoring, sensible timetabling for first and second-year teachers, and time for middle leaders to actually lead their teams tend to be cheaper than the recruitment costs that follow when they go.
What heads of department and pastoral leads can do
Most middle leaders cannot rewrite a whole-school marking policy. There is still a meaningful amount of ground inside a department or year team where wellbeing tends to be made or broken.
Start with how your meetings run. Departmental meetings that exist mainly to relay information from above could in many cases be an email. Meetings that focus on a shared problem (a topic the class is struggling with, a moderation issue, a tweak to the scheme of work) tend to be the ones colleagues find useful, and they reduce isolation in a way that broadcast meetings do not.
Second, be honest about workload signals. If you set a deadline for marking, ask yourself whether you would meet it comfortably given the actual teaching load. If you would not, the signal is that the official load and the realistic load are different things.
Third, watch for the early signs of someone struggling. A colleague going quiet in meetings, declining the after-school drink, taking more days off, marking more thinly. None of these on their own is diagnostic. Together they are often a signal that a conversation is worth having sooner rather than later. The Education Support helpline (08000 562 561) is a confidential first port of call that does not require the school to be involved.
Resist the urge to fix it in one conversation. If a colleague tells you they are struggling, the most useful first response is usually to listen, take it seriously, and offer to think through next steps together over the next week. Treating it as a problem you can solve on the spot tends to shut the conversation down before it has properly opened.
What SLT can do
Senior leaders carry the heaviest version of this problem. The Wellbeing Index has consistently found that heads and deputies report higher stress than classroom teachers, and the accountability pressure is genuinely different at that level. Acknowledging that is the right starting point.
The most useful thing SLT can do is to be explicit and consistent about what the school is not asking of staff. A short, public list of "things we have stopped doing" tends to do more for trust than a long list of new wellbeing initiatives. If marking has been reduced, say so. If a tracker has been dropped, say so. If lesson plan templates have been pared back, send the example. Staff need to see that workload reduction is real and not just rhetorical.
The second move is to be careful about how data is used. Performance management data, mock exam results, and intervention reports all serve a purpose, but they also create anticipatory anxiety in ways that often outweigh their information value. The schools that handle this well tend to be the ones where data conversations focus on what to do next, not on who is responsible for the gap.
The third move is to invest in the conditions that make pastoral work sustainable. This usually means a properly funded pastoral team, clear DSL cover, time for form tutors to do the job of form tutoring, and external mental health partnerships that staff can actually refer into. The Mental Health Support Teams (MHSTs) being rolled out in schools across England are one route. Charity partnerships with Place2Be, Anna Freud, or Mind also feature in many schools that have made progress here.
Practical checklist for a school audit
Staff wellbeing audit prompts
Use this as a starting point for an SLT or pastoral leadership team conversation. Not all questions will be relevant to every setting, but each one tends to surface something worth talking about.
- When did we last audit how staff actually spend their week, including evenings and weekends?
- Which three policies (marking, planning, data) create the most workload, and what would a lighter version look like?
- Is PPA time genuinely protected, or is it routinely eaten by cover and meetings?
- Do form tutors and classroom teachers have a clear, documented pathway when a student needs mental health support?
- How are ECTs and middle leaders supported in their first two years, and what is the early-leaver pattern?
- Are wellbeing initiatives focused on the system or the individual, and what is the balance between them?
- What does the staff exit-interview data tell us, and how is that information used?
- Is there a confidential route for staff to raise wellbeing concerns that does not go through line management?
Where Cognito fits, briefly
One small piece of the workload picture is the time teachers spend producing revision materials, retrieval questions, and end-of-topic quizzes from scratch. Cognito gives departments a ready-made bank of exam-style questions and video lessons mapped to GCSE and A-level specifications, which some schools use to hand back planning time. That is not a wellbeing strategy on its own, but it does sit in the same workload-reduction conversation as marking policies and meeting audits.
