Where a school has a cohort of less than 20 students taking the IBDP exams in a year, we list those schools in this small cohort table. This group does contain some very good academic schools, but parents need to be aware that with less than 20 students there may not be a full range of subjects available. Schools with less than 10 we completely avoid.
