<p>Some school districts subsidize students the AP exam fees just to make on this ranking list. I have to give Jay Mathews credit to include E and E% value in this year ranking. E and E % stands for equity and excellence percentage: the portion of all graduating seniors at a school that had at least one passing grade on one AP or IB test. I think the ranking should listed by E and E % value. It makes nonsense that Jefferson County ranks No.2 with only 50 in E and E%. It’s even ridiculous that LSU Laboratory ranks No.201 with only 2 in E and E%.</p>
