## AMC Statistics — Alabama Shows Measurable Improvement on AMC 10 Exams

Posted by: Mathew Crawford in Alabama, AMC, Competitions, Mathematics, The MIST Academy EffectEach year I judge what I’m doing here at MIST Academy partially by the AMC statistics.Â The 2011 statistics for the AMC 10 and 12 A & B exams have been released.Â I pay more attention to the AMC 10 than the AMC 12 because only a few of my students are yet old enough to be taking the AMC 12, though I suspect I would find mildly favorable results.Â Instead I focus my analysis on the AMC 10 exams that scores of my students take each year.

2010:

1.72% of total test takers qualified for the AIME.

0.93% of Alabama test takers qualified for the AIME.

The Alabama/Total qualification rate ratio was about .538.

2011:

4.94% of total test takers qualified for the AIME.

3.29% of test takers in Alabama qualified for the AIME.

The Alabama/Total qualification rate ratio was about .666.

Note that these statistics include test takers in other countries that often include a selection bias.

The increase in the relative rate is 23.8%, which is substantial for a single year.Â I believe that next year will show an additional jump that may be just as large due to a very strong 9th grade class and an exceptionally deep 8th grade class.

Of the 21 qualifying scores on the AMC 10 exams in Alabama, at least 13 were by MIST Academy students and some others used materials written by MIST Academy instructors to study, though I don’t yet know some of those results — the 13 number is a lower bound.
