By 2024, the system of streaming secondary school students into Express, Normal (Academic) or Normal (Technical) based on their PSLE results will be replaced by subject-based banding, or SBB, where students take a combination of subjects from three different bands based on their strengths.

SBB is already practised in primary schools. In secondary schools, SBB is now used for the four core subjects - the two languages, mathematics and science. In 2024, SBB will be expanded to cover all subjects in secondary schools. Implementing SBB at secondary schools is a logical step based on pedagogical customisation.
