IB Exam Score Distributions – 2017

The following tables compare the IB exam scores for Douglas County High School students with the Global scores, for the subjects offered in the DCHS IB program. To earn an IB Diploma, students must score 24 of 45 possible points across six subject exams, thus averaging a 4 on each exam (a 4 is also the minimum score accepted by colleges for college course credit). Of these 24 points, 12 must be in an HL (‘higher level’) subject, of which students take a minimum of 3.

2017 saw the highest IB Diploma rate of any DCHS IB class, exceeding the Global rate for the first time (80 compared to 78%). From the stats below, it appears that this was achieved on the strength of exceptional scores in English HL, Spanish SL, and Math Studies SL, the latter of which saw tremendous improvement from previous years.

We remain concerned, though, about how few students score 6s and 7s on exams. The difference between a 6 or 7 and a 4 or 5 score could mean that a student gets a year of college credit for a course instead of just a semester. In many courses, Global rates of 6 and 7 scores are much higher:  3x more in History, 5x more in Economics HL, 6x more in Chemistry, 8x more in French HL, 19x more in Biology, and infinite times more in Visual Arts (no one scoring at that level!). Why aren’t more of these students – the creme de la creme of Douglas County schools – scoring at the top levels on these exams?














Global scores were obtained from the official IB Statistical Bulletin. DCHS scores were obtained by open records request from the Douglas County School System.
