The International Olympiad on English Language, Leadership & Sustainability (IOELLS) is a signature initiative of GEIST International Foundation and the Global Innovation & Leadership Center (GILC). First launched in 2019 in Hanoi, Vietnam, the Olympiad responds to the global demand for strong communication and leadership skills in English to tackle modern challenges. It provides young people with a platform to strengthen language fluency, leadership abilities, and intercultural understanding. In 2020, IOELLS was held virtually, drawing participants from 20 countries across six continents. The event returned to Hanoi in 2023, where 50 Bangladeshi students took part. The fourth edition was hosted in Malaysia in July 2024, followed by the fifth in Bangkok, Thailand. Through these gatherings, youth leaders not only sharpen essential skills but also build international networks, positioning themselves to contribute to sustainable development goals. Bangladeshi national champions continue to represent the country on this global stage, showcasing their talent and commitment to driving positive change.
