Schools are one of the few environments where the standard interval is easy and the actual job is hard.
The interval is easy because a classroom is a benign environment. The job is hard because a school owns an enormous number of electrical items, acquires them through half a dozen uncontrolled routes, and the people most exposed to them cannot assess risk at all.
Why schools are treated differently
Not by the standard — AS/NZS 3760 treats a classroom much as it treats an office. The difference is in the duty and in the practicalities.
The people at risk are children. An adult in a workshop notices a cracked plug or a hot cord and stops. A seven-year-old does not, and a two-year-old in an ECE centre will investigate it. "So far as is reasonably practicable" is assessed against who is exposed, and this is about as exposed as it gets.
The asset base is chaotic. Purchased IT, PTA-funded gear, donations, teacher-owned equipment, items inherited from a closed school, things bought at a gala, and a music room full of amplifiers nobody has looked at since 2009.
Equipment moves constantly. Between rooms, to camp, to the hall for productions, home over the holidays and back again.
Scrutiny is high and public. Boards, ERO, parents, and — in an incident — the media. The question after an incident is never "did you have a legal obligation to test". It is "what did you do to keep them safe, and can you show us".
Your actual obligation
A school is a PCBU under the Health and Safety at Work Act 2015. That means a duty to ensure, so far as is reasonably practicable, the health and safety of workers and of other people affected by the work — which is squarely the students.
No law names test and tag for schools. The duty to manage the risk and to be able to demonstrate how you did is real, and testing is the accepted way of demonstrating it. The full reasoning is in what the law actually requires of you.
For a board of trustees, the practical framing is this: you are not being asked whether to buy tags. You are being asked whether, if something happened next term, the school could produce a record showing it had a system.
Intervals by area
A school is not one environment, and treating it as one is the most common and most expensive mistake.
| Area | Typical interval | Why |
|---|---|---|
| Classrooms, offices, library | 12 months | Controlled indoor environment, light handling |
| Fixed classroom IT that never moves | Up to 5 years | Qualifies for the low-risk allowance with a documented risk assessment |
| Technology and workshop rooms | 6 months, or 3 for hand-held | Hand tools, flexing leads, dust, students using them |
| Food technology rooms and canteen | 6 months | Heat, steam, moisture, constant handling |
| Science labs | 6 months | Heat sources, liquids, shared equipment |
| Performing arts, hall, AV and music | 6 months | Leads constantly rigged, de-rigged, coiled and trodden on |
| Caretaker and grounds equipment | 3–6 months | Outdoors, damp, physical abuse |
| Portable heaters and fans | 12 months, plus a check before winter | Seasonal storage, cords crushed in cupboards |
| Early childhood play areas | 12 months, with frequent visual checks | Children have direct access |
The five-year allowance on fixed IT is worth real money to a school with a lot of desktops and interactive panels. It is only available with a documented risk assessment on file, and the equipment has to genuinely not move. See how often you should test and tag.
The categories that get missed
Every school. Every time. This is the list worth walking around with.
Staff-brought appliances. Personal heaters, kettles, jugs, desk lamps, phone chargers, fairy lights in December. They never go through purchasing, so they are invisible to any register built from purchase records. They are also, disproportionately, the oldest electrical items in the building.
Donated equipment. Schools receive a lot of it, with no history. It should be tested before it enters service, like any second-hand item — see do new appliances need testing.
The music room and the hall. Amplifiers, PA gear, stage lighting, and a box of leads that has been growing since the nineties. Stage lighting in particular runs hot and gets handled by students.
Extension leads and multi-boxes. In a school these breed. They end up daisy-chained under desks, run under doors, and taped across floors for productions.
Sports and camp gear. Anything that goes off site and comes back damp.
The staffroom. Usually the highest density of old appliances in the school, and usually nobody's responsibility.
Holiday programmes and after-school care. Equipment brought in by a third party operating from your building, using your outlets.
The single most useful thing a school can do costs nothing: tell staff that anything electrical they bring from home needs to be logged before it is plugged in. Not banned — logged. A one-line email at the start of each term catches more risk than an extra testing round.
RCD protection matters more here
Testing tells you an item was sound on a date. An RCD is what protects a child on all the days in between.
WorkSafe is explicit that whether equipment is tested and tagged or not, it still needs to be RCD-protected in certain circumstances, such as outside in the damp. In a school that means grounds equipment, outdoor power for events, wash-down areas, and anywhere a hose and a socket coexist.
There is also a specific point worth raising with your electrician: the Electricity (Safety) Regulations 2010 contemplate a lower 10 mA rated residual current where an RCD is protecting children from direct contact with electricity, rather than the usual 30 mA. Whether that applies to a given circuit in your school is a design question, but it is a question worth asking rather than assuming.
More in when are RCDs required in New Zealand.
Building it into the school year
Timing is most of the battle in a school, because access is the constraint.
Term breaks are the obvious window for classrooms — empty rooms, no disruption, and equipment where it normally lives rather than in a cupboard.
But not everything should be done in the holidays. Testing a technology room when the students are away means testing it in its cleanest, most orderly state, which is not the state it is in during term. Some of the most useful findings come from walking a room in week six.
Avoid the last week of the year. Equipment is being packed, moved and lent out. Whatever you record will be wrong by February.
Do the heater check before winter, not during it. Heaters come out of storage with crushed cords every year.
A workable rhythm for most schools: main round in the January or April break, workshop and food tech round mid-year, heater and seasonal check before term 2, and a standing instruction that anything new gets logged on arrival.
What the board needs to see
Boards do not need the register. They need to know a system exists and is running. Four things, once a year, on one page:
- Coverage — how many items are on the register, and when the last full round was.
- Anything overdue, and why.
- Failures and what happened to them — this is the one that shows the system works. A report with no failures usually means nobody looked properly.
- The intervals and the reasoning, so the board can see the decision was made rather than inherited.
If your school cannot produce those four things today, that gap is the thing to fix — not the number of tags. We will walk a school and tell you where you stand at no cost, including when the answer is that your current provider is doing it properly.
