Hate the cliche but…it depends on the specifics. Somebody who was average, showed in 3’ or under with no zone or national achievements, coming back at age 50 after three kids is one thing. Medal Finalist, Junior, Derby etc on the AA rated circuit for years coming back at age 33 is another.
Case by case basis is the way it’s been handled with the affiliates I have been a member of. Novice anything is not Nationally rated. Depends on if there are any other suitable classes too. If there are no lower height open classes, all are restricted to novice it could mean they don’t show if age, illness or injury limit how high they can compete.
Think OP is asking on behalf of a client or maybe about one who pinned above her client, she’s a Pro, that would be unethical.
