Eight scoring bands known as Achievement levels (ALs) will replace the current PSLE T-score.
The changes take effect in 2021, which means those who started Primary 1 this year will be affected.
As many pupils may have a similar score, other tie-breaking factors will be considered when posting them to secondary schools. This includes citizenship, choice order of the school and computerised balloting.
