Teacher Workload: Evidence-Based Approaches That Actually Reduce Burnout

England has a teacher retention crisis. Approximately one-third of new teachers leave the profession within five years. The most commonly cited reason is not pay — though pay matters — but workload. The data on what teachers actually spend their time on, and what is educationally beneficial versus what is bureaucratic overhead, points clearly to what needs to change. This is the evidence-based guide for teachers and leaders.

What the Data Shows About Teacher Time

The 2019 Teacher Workload Survey — the most comprehensive survey of its kind in England — found that primary teachers worked an average of 54.4 hours per week and secondary teachers 49.5 hours, significantly above their contracted hours. More importantly, the survey found that the activities teachers most wanted to reduce were marking, administrative tasks and data recording — not the activities most directly connected to teaching quality. Only 42% of teachers' time was spent on direct classroom activity.

The implication is stark: a substantial proportion of what teachers are required to do has a weak evidence base for improving pupil outcomes and a strong evidence base for increasing burnout. The DfE's own workload reduction toolkit identifies three priority areas: marking, planning and data management. Reducing unnecessary work in these three areas would recover approximately 20% of teacher time currently spent on low-value activities.

Marking: The Biggest Workload Driver

Marking is the single largest contributor to teacher workload beyond direct teaching time, and it is also the area where the evidence for impact is most mixed. Extensive written marking — lengthy comments on every piece of work — is not significantly more effective than minimal written feedback or verbal feedback, according to the EEF's review. The marking that demonstrably improves outcomes is specific, actionable and responded to by pupils. The marking that demonstrates nothing beyond teacher effort is not. This means three detailed comments on a piece of work that the pupil reads, acts upon and responds to is more valuable than ten comments on a piece of work that the pupil glances at and files.

Practical workload-reduction strategies for marking: whole-class feedback (a single document addressing common errors seen across the class, without individual marking); verbal feedback recorded briefly; live marking during lesson time; peer and self-assessment with teacher moderation; and triage marking that distinguishes work needing detailed response from work that only needs acknowledgment. For the evidence on what feedback actually improves learning, see our companion article on the feedback that actually changes learning.

Planning: Doing Less, Better

Over-planning — creating bespoke lesson resources from scratch for every lesson — is another major workload driver with weak evidence for improved outcomes. The DfE's planning review found that teachers spending more time on lesson planning did not produce better pupil outcomes than those spending less time, suggesting that plan quality matters more than plan duration.

Workload-reduction strategies for planning: using well-designed shared resources and building on existing high-quality materials rather than creating from scratch; planning at the unit level before the lesson level; collaborative planning in departments that distributes the load; and using retrieval practice and interleaving (which reduce the need for entirely new resources by reusing and recombining existing material).

Data and Administration

Data collection and entry is consistently identified as among the most demoralising and least educationally valuable tasks teachers are required to do. The DfE guidance is clear that data should only be collected when there is a clear and specific use for it. If your school collects data that nobody looks at, that goes into a system that never produces useful analysis, that duplicates information available elsewhere, that question the purpose and whether the time could be better spent.

The Leadership Responsibility

Individual teacher strategies help at the margins. Systemic workload reduction requires leadership decisions: about marking policies that do not require extensive written comments; about planning expectations that trust teachers' professional judgment; about data collection that is genuinely purposeful; and about meeting cultures that protect professional time. Our article on adaptive teaching beyond differentiation addresses how planning can be made more efficient without reducing quality. The broader picture of teacher recruitment and what it means for schools is in our article on the teacher shortage crisis.

Frequently Asked Questions

Is workload a leadership problem or an individual teacher problem?

Both, but primarily leadership. Individual teachers can make marginal gains through efficiency. Genuine workload reduction requires leadership decisions about marking policies, planning expectations and data requirements. If your school's policies are driving unsustainable workload, the right response is to raise this through union representation or direct conversation with leadership.

My school requires detailed written marking. What can I do?

Raise the EEF evidence with your department head or marking policy lead. Schools are increasingly willing to update policies in light of evidence. The DfE workload toolkit provides language for the conversation. If individual change is not possible, focus your detailed marking on the work where it matters most, and use more efficient approaches elsewhere.

How do I manage work-life balance during exam season?

Set a finishing time each day and respect it. Plan your marking load across the full term rather than leaving it to accumulate. Use batch marking with a clear scheme rather than marking each script holistically from scratch. Prioritise sleep: the research on teacher cognitive performance with inadequate sleep is unambiguous.

What does the evidence say about the four-day working week for teachers?

Trials in other sectors show productivity maintained with a four-day week for knowledge workers. Education trials are limited. The mechanism — increased focus and reduced presenteeism — is plausible for teaching. The practical implementation of a four-day teaching week raises complex questions about curriculum time that differ from office-based contexts.
