The class stays the same, its participants change
An open class is a recurring class offering with changing attendance. The name in the weekly schedule connects the sessions, but does not define a fixed group. For your administration, two levels are therefore important: the offering, with its style and requirements, and each individual class session, with its date, capacity and confirmed spots.
The open format needs to suit the class. In a Dancehall class, a self-contained combination can allow people to attend a single session. This does not mean that every class has to teach the basics. An open practice session can also make sense for Bharatanatyam if participants already have the necessary movement foundations. But if the instructor builds up a repertoire over several weeks that depends on earlier material, changing attendance makes it harder for participants to keep up.
Open therefore does not mean there are no prerequisites. The subject-specific entry requirement is the same for everyone, regardless of how they pay. How you assess class levels and prior knowledge is a separate decision. What matters here is applying it consistently: having a spot available does not automatically make someone a suitable participant. Conversely, being a good fit does not guarantee a spot in a full session.
