As per the governing body World Athletics (WA), a NOC was allowed to enter up to three qualified athletes in each individual event and one qualified relay team if the Olympic Qualifying Standards (OQS) had been met during the qualifying period at the events approved by WA. The remaining places are allocated based on the World Athletics Rankings which were derived from the average of the best five results for an athlete over the designated qualifying period, weighted by the importance of the meet. The qualification window for race events on the program was from 1 July 2023 to 30 June 2024.^[9][10] Brunei qualified one sprinter to compete at the 2024 Summer Olympics.^[11]

As per the World Aquatics guidelines, a NOC was permitted to enter a maximum of two qualified athletes in each individual event, who have achieved the Olympic Qualifying Time.
