It’s a common rule of thumb that it can cost five times as much to attract a new customer as it does to keep an existing one.
One of the most valuable things you can do is look after your current contacts and strengthen relationships with people who have already shown an interest in your centre.
Anyone who has made contact should be viewed as a ‘warm prospect’.

You can then keep them informed and encourage them to take up learning at some point in the future.
You will have to find a way to collect data about your contacts, and build relationships.
