Puzzling over Fleming County High School results

On the one hand, the Herald-Leader reports that a state audit has said that that Fleming County high school's principal "should be removed because of a lack of academic progress."

On the other hand, Fleming's school report card says the school's overall score went up nearly five points in one year, putting it in the 87th percentile of schools statewide.  Here's a screenshot:

Puzzled, I went to another level of detail, checking out the five components that make up that overall score:

Here's what I see in these numbers:

• In achievement and in gap, Fleming is clearly behind state average. Those two results come from K-PREP scores.
• On growth, Fleming is just slightly above state average. The growth measure  looks at how individual students' reading and math scores changed from grade 10 to grade 11.
• In graduation, Fleming  has a nice, but not vast, lead over the state.
• It's readiness that soars above the state, based on students qualifying as ready for college and career as measured by ACT and other tests of readiness for college and career.
• Finally, the overall score is an average of the other five elements, treating all five as having equal weight, rather like a grade point average--and Fleming County High comes out ahead of the state average for high schools.

Looking at it all,  I can see an argument for weak results, based on achievement and gap, and I can see an argument for great results, based on readiness and graduation.  From the overall score, it looks like state policy sees the combined results as pretty strong.

So far, I've ended up with a new puzzle: How can a school's readiness results be so different from achievement?  I think the two approaches are supposed to be measuring the same students on roughly the same content and skills--but clearly they're identifying quite different views of this particular school.
