Education Ministry sports division director Ee Hong said they had an agreement with all sports associations on the authority over selection of students for competitions.
She said the priority was for BJSS students to compete in school events.
On Tuesday, BJSS came under the microscope when two of their top junior badminton players, Soong Joo Vern and Darren Isaac Devadass, walked out because they wanted to compete in the Asian Junior Championships instead of the Asean Schools meet.
