STAR is very complicated - I'm not going to go into it more than to point out the FAQ entry above that another poster references.

Hi Dallas,

Thank you for explanation!

My son, a junior, turned 16 a month or so ago. Last year, we updated his actual graduation year and we saw his "ranking" lowered from about 200 to over 300, a little over 100 spots. I guess a year difference in graduation would probably move about 100 spots in your master list.

But I did notice that blue chips are different. Henrik Wiersholm's ranking was lowered from #1 sophomore to #6 junior after he updated his actual graduation year.
