Curriculum and Activities

All Grade 6–10 students follow the IB Middle Years Programme curriculum and take International Schools’ Assessment standardised tests each year. All students in Grades 11 and 12 follow IB Diploma Programme courses leading to external IB examinations. Students have the option of taking IB certificates in place of the full IB Diploma. All qualifying students also receive an accredited U.S. high school diploma. Students in Grade 10 undertake a Personal Project which is externally assessed by the IB, Halcyon offers a wide range of extracurricular activities.

IB Diploma Programme and Assessment

Grading for each subject is reported on the transcript and follows the IB assessment criteria based on the 7-point scale. Assessment criteria are rigorously upheld. Grades are issued at the end of each term. Due to the high mobility and international backgrounds of the student body, as well as our small class sizes, Halcyon does not provide a class ranking.

The translation of our assessments as compared with a typical American high school grading system is approximately:

7 = A+
6 = A
5 = A-/B+/B
4 = B/C+
3 = C
2 = D
1 = F
