A parent enrols one of three children because that is what she can afford. The other two want to go. The school has space in the same class on the same evening and she is already driving there.
Nobody offers her anything, so she books one. Two enrolments with almost no marginal cost are sitting in her car in the car park every week.
1. Understand the marginal economics
A second child in a class that already runs costs the school almost nothing. Any rate above zero is profitable, which makes this the easiest revenue available.
2. Publish the family rate
On the pricing page, not offered on request. Families budget before they enquire, and a rate they cannot see does not affect their decision.
3. Consider a capped family price
One figure for the whole household regardless of numbers. It is simple, generous sounding and it makes larger families feel welcome rather than expensive.
4. Define family broadly
Siblings, a parent training alongside a child, and households that do not fit a standard shape. A narrow definition creates awkward conversations at the desk.
5. Encourage parents to train too
A parent sitting on a bench for an hour is a potential member. Offering them a rate to join the adult class is the most overlooked growth available.
6. Schedule to make it possible
Junior and adult classes back to back, or siblings in adjacent slots. A family that can do everything in one trip attends far more reliably.
7. Apply the discount to gradings and equipment too
Families feel the extras multiplied by three, which is the arithmetic set out in grading, uniform and membership questions at a dojo.
8. Run a second hand uniform exchange
Three children outgrowing kit is a real cost, and a school that solves it is one families talk about.
9. Handle the children at different levels
Siblings frequently train at different stages, and a timetable that separates them entirely defeats the convenience that made it work.
10. Say what happens when one child stops
Whether the family rate continues, reduces or ends. Deciding in advance avoids a difficult conversation at exactly the wrong moment.
10b. Decide what happens during a quiet term
Families with three members training feel the cost most in a month where illness or exams keep everybody at home. A short freeze available once a year costs the school almost nothing and prevents a household cancelling everything at once during a difficult few weeks.
11. Ask about siblings at every enquiry
A single question, asked every time. Many parents do not raise it because they assume the answer is one price each.
12. Make the trial available to the whole family
A trial for one child and a full price for another is a barrier. Let them all try.
13. Watch the retention effect
Families with several members training leave far less often, because stopping is a household decision rather than an individual one.
14. Borrow from membership organisations
The structures used in family and sibling membership questions at clubs and ai assistant membership organisations transfer directly.
15. Consider the households you are not reaching
Families managing health conditions or caring responsibilities have their own constraints, in the way described in home visit physiotherapy enquiries from families.
16. Ask the sibling question automatically
An assistant that asks how many children are interested, their ages, and whether a parent would like to train, then quotes the family rate, converts one enrolment into three. See pricing, run the numbers on the chatbot ROI calculator, and the sector view sits under fitness.
