Academic Performance

In addition to a range formative and summative internal assessments, external examinations provide another measure of academic performance for students in some grades at YIS. Specifically, our students in grades 3 - 9 take the International Schools Assessment and our grade 12 students take the IB Diploma exams at the end of their senior year. Results of these examinations for the most recent academic year are shown below. In addition, a number of YIS high school students elect to take the SAT and/or ACT exams for university admission in the U.S. Keep in mind that we are an inclusive school and for well over half of our students English is not their first language. Read about our Assessment Policy.

ISA Results

In grades 3 through 9 we conduct the International Schools’ Assessment (ISA), which is a standardized assessment in mathematical literacy, reading and writing. This test is taken by thousands of students at other international and national schools. To find out more about the ISA testing program, please visit the ISA website. A summary of mean test scores from the ISA assessment in the 2017-18 school year is shown below along with the mean scores of other international schools worldwide.

IBDP Results


Although YIS has a non-selective admissions policy, our students' IBDP examination results are consistently well above the global average. While many schools offer the IBDP as a selective program open only to the highest performing students, all YIS students entering grade 11 are given the opportunity to pursue the IB diploma, and the great majority of them achieve that goal. Here are our IBDP exam results for the past five years.

** Average for those receiving diploma. International average score 29.63 points.

A perfect score for the IB Diploma is 45 points. Students may earn up to 7 points in each of the six subjects they choose. Up to 3 additional points may be gained from the results of their Extended Essay and Theory of Knowledge. For more information on YIS students' academic achievements, please see the High School Profile for College and University Admissions.
