To continually grow your martial arts school, leveraging your current students for referrals is a highly effective strategy. Implement methods such as requiring referrals for rank promotions, offering merchandise incentives, and hosting special events like "buddy days" or ladies' self-defense clinics. Communicate the benefits of referrals clearly, recognize students who help with growth, and consider family discounts and birthday parties as additional ways to boost enrollment. Utilize these techniques wisely to enhance your referral program and increase your student base.
