The £40 Supply TA Bag: What Earns Its Place, What Doesn’t

Supply work has its own rhythm. You get the message at 7am, you find the school, you meet the office team, and by 8:30 you’re standing in a classroom trying to look like you’ve always known where the glue sticks live. A good bag won’t turn a tricky day into a perfect one, but it removes a lot of small friction. And small friction is exactly what makes a supply day feel harder than it needs to.

Start with the bag, not the shopping list

Any sturdy tote, backpack or small holdall works. You don’t need a special ‘teaching assistant bag’ — that’s not a thing, and if someone tries to sell you one for £65, walk away. What matters is that it opens easily, sits on the floor without falling over, and has a pocket you can actually find things in.

The aim here is a kit that costs around £35–£40 if you’re starting from scratch. Most TAs will already own half of it. Buy cheap, replaceable versions of the rest, and label anything you’d be annoyed to lose.

The 12 things worth carrying

1. Two pens, two pencils and a whiteboard marker. Cheap, boring, endlessly useful. Schools do supply these, but not always in the room you’re in, and not always before you need them. A spare pen also means you can lend one without quietly fuming about it.

2. A basic visual timer. A simple kitchen timer costs around £5 and does the same job as a fancy classroom one. It’s brilliant for ‘ten minutes of quiet reading’, tidy-up warnings, and helping a child see that a task does, in fact, end.

3. Stickers or small reward slips — only if the school allows them. Check first. Some schools have a whole reward system, some have none, and some have a policy about not introducing your own. If in doubt, ask the office or the class teacher before you start handing out sparkly dinosaurs.

4. A small notebook and sticky notes. For timetable changes, a child’s name you don’t want to forget, or the fact that Year 4 goes to assembly at 10:15, not 10:30. Sticky notes are also useful for leaving a tidy handover at the end of the day.

5. A charging cable and a compact power bank. Your phone is your alarm, your agency contact and your map. A flat battery on a supply day is a special kind of stress. Keep the cable in a small pouch so it doesn’t knot itself around your keys.

6. A watch. Not every classroom has a visible clock, and you won’t always be able to check your phone. A cheap digital watch is enough. It also helps you avoid the ‘is it lunchtime yet?’ panic spiral.

7. A refillable water bottle. Obvious, but easy to forget when you’re leaving in a hurry. Choose one that seals properly. You do not want it leaking over the reading records.

8. Hand sanitiser and pocket tissues. Supply TAs meet a lot of door handles, shared pencils and small people with colds. This is not about being precious; it’s about getting through the day without running to the staff toilet every twenty minutes.

9. A document wallet or A5 folder. Somewhere to put worksheets, timetable printouts and the little notes that otherwise turn into confetti at the bottom of your bag. A plastic wallet costs about £2 and saves a lot of scrabbling.

10. A pack of playing cards or a couple of dice. Useful for quick fillers, number games and calm transition moments. Keep it simple and age-appropriate. You are not running a magic show; you just want something that works when five minutes appear out of nowhere.

11. A small pack of wet wipes. For sticky tables, mystery marks and the general reality of school life. Not glamorous, but genuinely earns its place.

12. A spare tote bag. Fold a thin one into your main bag. It’s there for the book you’re asked to take to the library, the wet painting, or the pile of letters that need to go home. Supply days generate paper.

Three things to leave at home

1. Edible rewards. A bag of sweets or biscuits feels kind, but it can create a minefield around allergies, school food policies and different family rules. You don’t want to be the supply TA who accidentally gives a child something they can’t have. Stick to school-approved rewards, or nothing at all.

2. Your own tablet or phone loaded with personal media. It’s tempting to bring a device with a few videos or games for a tricky moment, but personal devices and personal content are a safeguarding and data-protection problem waiting to happen. Use school equipment and school-approved resources only.

3. A personal first-aid kit. Well-meant, but not your call. Schools have their own procedures, supplies and trained staff. If a child needs first aid, follow the school’s system. A personal kit can create infection-control and policy issues, even when you’re trying to help.

How to build it without overspending

Start by raiding your own drawers. Most of us already have pens, a notebook, a cable and a tote bag. Then buy the few bits that genuinely make a difference: a timer, a cheap watch if you don’t wear one, and a small power bank. Supermarkets, stationery shops and online marketplaces all sell versions for a few pounds. There’s no need to buy the expensive ‘teacher’ version of anything.

Label your stuff. Not because anyone is likely to steal it, but because staffrooms are busy places and things migrate. A strip of coloured tape on your timer and charger saves a lot of ‘have you seen my…’ messages at 3:30pm.

And check the school’s policy before using anything that feels like a reward, a treat or a behaviour tool. A quick question at the start of the day is far better than an awkward conversation later.

The bag is there to support you, not define you

You don’t need a perfect kit to be a good supply TA. You need to be reliable, calm and willing to ask where the toilets are. The bag just makes the practical side a bit lighter. Pack what earns its place, leave the rest at home, and remember that the best supply TAs are the ones who adapt to the school in front of them — not the ones with the biggest bag.
