School Profile

Academics: The International School of Ulaanbaatar (ISU) offers a rigorous academic programme that embodies the philosophy of the International Baccalaureate Organization (IB). The language of instruction is English.  Students in Pre-kindergarten to Grade 5 follow the Primary Years Programme and in Grades 6 to 10, the Middle Years Programme. In Grades 11 and 12, students are enrolled for the IB Diploma.  At ISU, we offer the following courses in each of the DP subject groups:

Group 1 – Language A: English, Mongolian

Group 2 – Second Language: French, English, Chinese, Spanish

Group 3 – Individuals and Societies: History, Economics, Business and Management

Group 4 – Experimental Sciences: Biology, Physics, Chemistry

Group 5 – Mathematics: Maths Standard, Maths Studies, Maths Higher

Group 6 – Arts and Electives: Visual Arts

In the DP, students study six (6) of the above courses, one from each group. Three (3) are pursued at Higher Level requiring 240 hours of instruction and three (3) at Standard Level requiring 150 hours of instruction. To be eligible for the IB Diploma at the conclusion of grade 12, all students must successfully complete the prescribed course work and sit an external examination. They must also submit an extended essay of 4000 words focused on one of their subject options. All DP students must complete a course called Theory of Knowledge (TOK) at the completion of which they submit an externally examined essay and present an internally-assessed seminar on their topic. As well, all DP students must (4) successfully meet the requirements for on-going creativity, action and service work (CAS) over their two years of DP study. To be awarded the IB Diploma, students must obtain a minimum overall point total of 24 out of a possible 45 point total.


Student Assessment and Grading: At ISU, students in the IB Diploma Programme are assessed on a 1-7 scale for each course. Therefore, with 6 courses being graded, they have an opportunity to earn a total of 42 points. They may earn an additional 3 points for exemplary performance in the TOK course and Extended Essay. Thus, the total point score is 45. Students are encouraged to take the SAT Reasoning Test in order to provide a complete picture of individual academic potential. ISU does not convert the IB point totals to any other grading systems. ISU does not calculate Grade Point Averages, percentage grades, nor assign letter grades. As a criterion-referenced, standards-based assessment system, it also does not rank students
