One of the most frustrating things as an instructor is when a prospective student randomly shows up to the school wanting to try out classes, without any prior contact or knowing when the appropriate time for that would be. Therefore, when someone contacts the school for information, most of us try to get them to commit to a day/time for either a free or paid trial. Recently, I've been using Calendly to schedule trial appointments and it's definitely increased the number of people who show up for their trials.
Calendly is free to use, however there are paid upgrades that I believe are beneficial. The "pro" account is only $15/month and includes email and text automations to follow up with those who book appointments, reminding them of their upcoming trial and increasing the likelihood that they attend.
For those of us we offer separate programs, or different beginner classes divided by age, Calendly has the option to create multiple calendars with the appropriate days and times. When speaking to a new lead, you can provide a link to your complete scheduling page (like this one) where they select the trial that best fits them, or you can link them to the calendar of your choosing.
Not everyone offers free trial classes. Some schools prefer to do paid trials, whether for a single class, a week, 30-days, etc. Because Calendly is integrated with Stripe, you have the option for this as well. Simply create a separate calendar with the days and times available for someone to start their trial, include how much it is, and they will be prompted to pay for the trial when booking their appointment.
To increase the number of trials booked, I recommend linking the calendar to your school's website. For example, this form appears on the home page of my school's site. When they click "Get Started Today" it takes them directly to the scheduling page where they can book their trial appointment. From there, with the upgraded Calendly account they begin receiving emails and texts reminding them of their appointment time/date. I also receive the information as an email so I can follow up with them directly to help build a connection.
As an added bonus, you can create a QR code to be printed on flyers, business cards, or window decals that direct people to scheduling a class, like these examples below:
