I thought maybe you were confused about what EA was because I couldn’t understand your question otherwise. If she’s not ready that’s another component to your question. You didn’t say that.
In general it’s better to do EA. Colleges do fill their slots and it’s such a relief to have that acceptance in hand.
My D22 has a friend who is at SCAD this year and she did do EA or rolling. She was accepted very early, like August or Sept of 2021.
I don’t know any specifics about Ringling. If her portfolio is not ready, though, then I guess she’s not ready to apply.
I would try to get it all ready by the EA deadline and apply EA if possible. I think it does make a huge difference for kids psychologically to get those apps in and be done aside from the fact that it may help with their chances.
