Ask a room of school owners where their students came from and most will say word of mouth. Ask them what share, and almost none can tell you.
That is the entire problem. The main growth channel is the one nobody manages.
Start by recording it
One field on the student record: how did you hear about us. Filled at enrolment, from a short fixed list, not free text.
Within a term you will know something you have been guessing at for years - and it usually reorders the marketing budget. Schools regularly discover that the channel they spend most on produces the fewest enrolments, while the one they spend nothing on produces most.
Ask at the moment of visible progress
Timing beats incentive. The wrong moment is enrolment, when the parent has no evidence yet. Another wrong moment is when you need students, which they can sense.
The right moment is just after something good and specific happened: a progress report they were pleased with, a first exam result, the day their quiet child spoke up. That is when a parent already wants to tell someone.
Ask plainly. "If you know another family looking for this, we have two places in the Tuesday class." One sentence, a specific opening, no form.
Reward carefully
Money for referrals sits badly with a lot of parents and can cheapen the recommendation. What works better, and costs about the same:
- A credit against next term's fees rather than cash.
- Something for the child, not the parent.
- Nothing at all, plus a genuine thank you and priority on the class they want.
Whichever you pick, make it the same for everybody and write it down. A reward negotiated case by case creates the impression the school has no rules.
A recommendation is a parent lending you their reputation. Price it too openly and you turn a favour into a transaction.
Make the referred family's first contact excellent
A referral arrives warm and cools faster than a cold enquiry, because expectations are higher. If the reply is slow, you have also embarrassed the family who recommended you - and you will not get a second one from them.
Treat referred enquiries as the priority in your response-time rule. See the enquiry that arrives at 9pm.
