Okay, I see.
Certainly you should include artistic directors, and then you have managing directors in arts organizations. You often have those two going hand-in-hand. Within the art gallery world, it's usually a director. It could be a director/curator position or director/CEO situation. If you want to capture that senior management level, you're going to have to go there. Often, within the smaller organizations, at least within the visual arts, your curator is your top position. You'd have to be grabbing all of those positions to get some deep data around this.
