State standards are set by class, not by talent
Most state associations publish one mark per classification and revise it every year or two off recent results. Iowa builds its standard from the last three years of third place marks. A 21-0 can be a comfortable qualifier in a small class and two feet short in the largest one, in the same state, on the same weekend. The marks high school girls typically jump against those cutoffs are in the high school girls' long jump ladder.
