Ask a teacher what the hardest part of the job is and most won't say the teaching. They'll say everything around the teaching — the marking, the admin, the meetings, and above all, the planning. Not because planning is inherently unpleasant, but because there's too much of it, it compounds weekly, and it eats into the time that should be recovery time.
The numbers
UK government surveys consistently show that teachers work well over 50 hours per week during term time. Of that, roughly 10–12 hours per week goes on lesson planning and preparation. For context, that's more than a standard part-time job's worth of work — on top of teaching itself, marking, meetings, and pastoral duties.
Secondary teachers with large timetables — five or six different classes across multiple year groups — bear the heaviest load. Each class needs a differentiated lesson, ideally linked to a scheme of work, updated to reflect where that particular group has got to. Multiply that by six and you understand why Sunday evenings have a particular dread in the teaching profession.
What planning time actually costs
The obvious cost is time. But the less obvious cost is cognitive depletion. Planning a lesson well requires real intellectual effort: thinking about the students, the content, the sequencing, the likely misconceptions, the differentiation. When that effort is happening at 10pm after a full day of teaching, it doesn't produce the same quality of thinking as when it happens with a clear head.
Tired planning produces safe planning. Safe planning produces routine lessons. Routine lessons produce disengaged students. The chain from overwork to poor outcomes runs through lesson quality, and lesson quality runs through planning time.
The retention problem
Teacher retention in the UK is in crisis. More teachers are leaving the profession within five years of qualifying than at any point in recent memory. Exit surveys consistently rank workload as the primary reason — and within workload, planning and admin are consistently cited.
This matters beyond the individual teacher. Every teacher who leaves takes years of subject knowledge, pedagogical experience, and relationship capital with them. The recruitment and training cost of replacing a teacher is substantial. A profession that cannot retain its people is consuming itself.
What reducing planning time actually enables
The argument for planning tools isn't just that they save time. It's what teachers do with that time instead. Teachers who reclaim two or three hours of planning time per week consistently report that they spend it on the relational work of teaching — talking to students, giving better feedback, thinking more carefully about individual needs. The things that actually improve outcomes.
A tool that generates a solid lesson plan in thirty seconds doesn't replace teacher thinking. It eliminates the blank-page problem and the mechanical work of formatting, so the thinking that remains is the thinking that matters.
The £15 argument
ScholaPlan costs £15 per year. If it saves a teacher even one hour of planning time per week, it returns its cost in the first working day. The economic case is not the point — but it does illustrate how different the value calculation is for a teacher versus the cost of the tool.
The real argument is simpler: teachers who spend less time on mechanical planning spend more time on teaching. And teaching better, with less exhaustion, is why most of them entered the profession in the first place.
