The global economic downturn has led to fewer international students enrolling in B.C. schools. Vancouver and Surrey, the province’s largest school districts, have experienced a five to seven per cent decrease. Korea has been a main source of international students in the past, but the recent plunge in the country’s currency has raised the cost of tuition, which is about $12,000 annually. The most significant dip is at the elementary level, where students typically enroll for a few months to improve their English.
