We now have grade distribution data for 2015 IB Exams on our website:

https://advocatingexcellence.org/2015-ib-exam-grade-distributions/

The tables show the percentages at each score level (1-7) for Douglas County High School students compared with the Global percentages. The school data was obtained from the local IB office and the Global data is published by IB in its annual Statistical Bulletin.

Of note is the fact that while the passing rates exceed the Global in a few areas, the % of students passing HL (higher level) exams is lower, and a much smaller proportion of DCHS students scored the highest marks of 6 or 7.
