Pooran started playing cricket when he was young, and while playing for Naparima College, he broke many records at the school level. Trinidad and Tobago later endorsed him, and he addressed them in different age gatherings. In 2012, when he was 16 years old, he made his national under-19 debut, and in 2013, he played for the West Indies under-19. He also played for his country in the 2014 Under-19 World Cup, scoring the tournament’s highest run total, 143, against Australia.
