December Done Right: Staying Festive and Focused in the Busiest Month of the Year

5th December 2025

TL;DR:

December is a whirlwind — productions, trips, cover spikes, last-minute sickness, assessments, and the emotional overload that comes with the end of term. This guide helps educators and school teams stay grounded, maintain professional boundaries, and focus on the “quick wins” that make December smoother. It’s festive, but it’s practical. Everything you need to finish the year well.

Why December Needs a Different Approach

December in schools is joyful — but it’s also one of the most demanding months for educators.

According to the Department for Education, staff absence rises significantly in the winter months, including December, which directly increases the need for internal and external cover.

Add to that:

  • Christmas productions
  • School trips
  • Class parties
  • Reports
  • Assessments
  • Behaviour fluctuations
  • Weather disruptions
  • End-of-term emotional fatigue

…and you’ve got a month that needs organisation, firm boundaries, and some celebration along the way.

This blog is your guide to getting December “done right”.

1. The Cover Peak: Staying Steady When Demand Rises

The last two weeks of term are historically high for:

  • sickness cover
  • SEND support needs
  • exam prep in secondary
  • trips requiring additional adults

Humly educators often describe December as dynamic but intense — and school leaders feel exactly the same.

A few quick wins to stay ahead of the cover curve:

✔ Keep your registers, seating plans, and brief handover notes up to date

It saves huge time when colleagues or supply educators step in.

✔ Use a shared calendar for trips and events

Helps identify days with likely staffing gaps.

✔ If you’re a supply educator — confirm your availability early

Schools need reliability.

2. Productions & Trips: Keep the Magic, Reduce the Chaos

December is when the school becomes a theatre, a concert hall, or a coach park. Brilliant — but busy.

Quick wins for trip days:

  • Have a printed group list
  • Pack a simple behaviour script for transitions
  • Assign “trip buddies”
  • Carry a small first-aid pouch (plasters, tissues, wipes)
  • Always have wet-weather contingencies

The Health and Safety Executive emphasises clear supervision ratios and risk awareness on school trips:

For productions:

  • Keep backstage areas calm
  • Assign one “runner” and one “behaviour anchor”
  • Stick to simple routines
  • Encourage low-pressure participation

A calm adult equals a calm cast.

3. When Behaviour Peaks: Stay Boundaried, Stay Consistent

Behaviour often shifts in December: excitement, tiredness, sugar, schedule changes — it’s predictable.

Research from the Education Endowment Foundation highlights that consistent routines and clear expectations reduce behaviour incidents, especially during high-disruption periods.

Quick wins:

  • Keep predictable routines wherever you can
  • Reduce cognitive load with clearer instructions
  • Offer countdowns before transitions
  • Use calm, consistent responses

4. Boundaries: Your Non-Negotiables for the End of Term

You cannot pour from an empty cup — especially in December.

Educator wellbeing is under more pressure than ever.
The Teacher Wellbeing Index 2025 reported that 77% of education staff have experienced symptoms of poor mental health related to work.

This month, protect:

  • Your time — no checking emails after a set hour
  • Your energy — simplify marking and planning
  • Your headspace — pause before reacting
  • Your boundaries — say no where needed

5. Quick Wins for a Calm Finish

Here’s how to make the final fortnight easier:

✔ Use “prep pockets”

Two minutes here and there saving tomorrow-you.

✔ Have a go-to sub lesson

Short, structured, low-stress activities for cover days.

✔ Keep communication light + frequent

The last thing anyone needs in December is confusion.

✔ Don’t overcomplicate festive activities

Children love simple, predictable tasks.

✔ End with gratitude

A 10-second “thank you” can steady a whole class.
