2015 IB Exam Grade Distributions

The following tables show the grade distributions of Douglas County High School students on IB Exams, by percent, compared with the Global norms. A score of 4 is considered passing; HL exams are more rigorous than SL exams. We have not yet posted 2016 data because the global score distributions have not been released.


IB students decide whether to take two years of Biology or two years of Chemistry.



Math Studies is a lower level course.

Social Sciences

Economics is an IB elective (called “6th subject”), so not all students take the class. The other electives, as of the 15-16 school year, are Visual Arts or a second foreign language.

Foreign Languages

Notice there are many more foreign language exams taken than in other subjects. This is because all juniors take an SL exam and there are always more juniors than seniors due to students dropping out of the IB program.


The Visual Arts exam is not a traditional “paper and pencil” test. Instead, students submit original artwork for evaluation.


While the passing rate is higher than the global average in 6 of 14 areas, it is lower for all the HL exams except for English. This is one of the main reasons why the Diploma Rate for students who completed all the program requirements (not all seniors do) was significantly lower than the global norm (54% compared with 81%). Also noteworthy is the fact that the percentage of students scoring at the highest bands (6 and 7) at DCHS is about three times lower than the global norms (8.5% compare with ~25%). This result is similar to AP Exams in Douglas County that year where 1.4% scored the highest score of 5 compared with 14% global.
