This is the most consequential misunderstanding in the sector, and it is nobody's fault in particular. The word ratio appears on play centre websites, it appears in childcare regulation, and it means two entirely different things in the two places.
The two kinds of ratio
An admission ratio is a venue's rule about how many children one adult may bring in. Typically something like one adult per three children under a certain age. It is a condition of entry. It exists because a single adult cannot supervise seven toddlers, and because a venue that lets them try is storing up trouble.
A staffing ratio is a rule about how many members of staff must be present per child. It applies in registered childcare, where the provider has taken charge of children in the absence of their parents, and the required numbers vary by age and setting.
Almost every ratio you meet at a play centre is the first kind. It is a rule about you, not a promise about them.
| Admission ratio | Staffing ratio | |
|---|---|---|
| What it governs | How many children one paying adult may bring in | How many staff must be present per child |
| Where it applies | Almost every commercial play centre | Registered childcare provision |
| Who it constrains | You | The provider |
| Who supervises | The accompanying adult, throughout | The provider's staff |
| Typical form | One adult per a stated number of children under a stated age | Numbers varying by the age of the children and the setting |
| What it promises about staffing | Nothing at all | A minimum staffing level that can be checked |
A working frame put together by this desk from published guidance and from the plain wording of the standards named on the page. It is not a survey, not a measurement and not drawn from any venue.
Who is responsible
In a general session at a commercial play centre, the adult responsible for supervising a child is the adult who brought them. That is the position almost universally set out in venue terms and it is what the format assumes.
This is not a venue trying to shirk anything. It is the structure of the product. You have bought access to a facility, in the way that you buy access to a swimming pool or a park, and you have not bought a childcare service. A venue that promised to supervise every child in a busy soft play frame would be promising something it could not deliver.
What a venue does owe you is a different set of duties: to keep the premises reasonably safe for the purpose you are there for, which is the general effect of occupiers' liability law, and to manage risk so far as is reasonably practicable under health and safety law. Those are real duties and they are not the same as watching your child.
Floor staff, and what they are for
If floor staff are not supervising individual children, what are they doing? Several things, and they are worth knowing because they tell you what to expect.
- Watching the equipment being used. Spotting a child on the wrong level, a blocked slide, a queue turning into pushing, or a toddler in the older children's area.
- Enforcing the rules. One at a time on the slide, no shoes, no food in the frame, height limits on the top level.
- Noticing incidents. A child crying inside the frame, a collision, a child who has been at the top for a long time and cannot get down.
- Retrieving. Getting a stuck child out, which is a genuine skill and one of the main reasons floor staff exist.
- First response. Being the person who is already there when something happens, and getting a first aider.
None of that is supervision of your child. All of it is the difference between a well run room and a chaotic one, and it is why a venue with somebody on the floor feels different from one with everybody behind the till.
When it becomes childcare
There is a category of session where the picture changes, and it is worth recognising.
If a venue offers to take charge of children while the accompanying adult leaves the building, it is providing childcare rather than a play session. That triggers a different regime, potentially including registration with Ofsted or the equivalent body in the relevant nation, staffing requirements, and vetting of staff.
Holiday clubs, drop off sessions and some structured classes may fall into this category. Some venues do it properly and are registered. Some offer something that looks like it and is not.
If you are being offered a session where you leave, the questions to ask are direct: are you registered, with whom, what is your registration number, what are your staffing ratios, and are your staff vetted. A properly registered provider answers all five without hesitation, because they have had to prove all five to somebody.
- Is your ratio a rule about how many children I can bring, or a staffing level?
- Who is on the floor during this session, and what is their role?
- Do you run any sessions where children are left without an accompanying adult?
- If so, are you registered as a childcare provider, and with whom?
- At a party, who is responsible for supervising the children?
Parties are a special case
A party is the situation where parents most often assume supervision has been handed over and it most often has not.
The usual arrangement is that a venue provides a host who runs the party: manages the food, organises the room, moves the group between spaces. That is a host, not a supervisor. The children are still the responsibility of the accompanying adults, which is a problem, because at a party those adults are frequently one parent and whoever else stayed.
The practical answer is to work out in advance who is watching whom, and to say so out loud to the other parents. It is not awkward. It is considerably less awkward than the alternative. What a party contract does and does not commit the venue to is covered in the piece on party contracts.
What supervision actually looks like
Since supervision is yours, it is worth being realistic about what you can do.
You cannot see into an enclosed frame, and pretending otherwise is a way to feel busy rather than be useful. What you can do is watch the exits from the structure, so you know roughly where your child is in the cycle, and keep the door in view.
You can agree a rule about doors, as discussed in the piece on entry and exit control.
You can choose a seat with a sightline rather than a comfortable one.
And if there are two adults, you can decide who is watching. Two adults each assuming the other has it is the standard failure and it takes four seconds to prevent.
