2014 AP Exam Score Distributions: AP CS had a big increase, bimodal scores

Barb will probably do her demographic analysis in the Fall. Gas Station Without Pumps analysis on raw scores is out now and is quite interesting.

The Computer Science A exam saw an increase of 33% in test takers, with about a 61% pass rate 3, 4, or 5. The exams scores were heavily bimodal, with peaks at scores of 4 and at 1.  I wonder whether the new AP CS courses that Google funded contributed more to the 4s or to the 1s. I also wonder whether the scores clustered by schools, with some schools doing a decent job of teaching Java syntax most of what the AP CS exam covers, so far as I can tell and some doing a terrible job, or whether the bimodal distribution is happening within classes also.  I suspect clustering by school is more prevalent. The bimodal distribution of scores was there in 2011, 2012, and 2013 also, so is not a new phenomenon.  Calculus BC sees a similar bimodal distribution in past years—the 2014 distribution is not available yet.
