FLEX students undergo a rigorous merit-based selection process. Academic performance, English language competence, and personal qualities are all important factors. On average, one in 40 applicants is selected. While in the United States, FLEX students participate in PAX Coordinator-designed enhancement activities. These special learning opportunities focus on American culture and diversity; government and democracy; entrepreneurship and free market economy; and leadership. In addition, these youth ambassadors complete at least 30 hours of volunteer work and are encouraged to apply for national workshops.
