(1) For a given year, the statistics are calculated based on the P1 cohort that would typically sit for these exams in that year. For example, for 2023, the percentage of the P1 cohort eligible for secondary school is calculated based on the cohort that entered P1 in 2018, and the percentage of the P1 cohort who achieved Grade D / 5 or better in at least 5 N-Level subjects or Grade C6 or better in at least 3 O-Level subjects is calculated based on the cohort that entered P1 in 2014. These figures may be different from those shown in Tables 33 to 53 as the latter are based on exam candidatures and not P1 cohorts, i.e., they would include students who enter the school system after P1 and exclude those who left the country after P1.
(2) Figures include students who achieved Grade D / 5 / C6 or better in 5 distinct subjects based on a combination of N- and O-Level subjects. For students offering ITE Skills Certificate or ITE Skills Subject Certificate courses, the equivalent N-Level grades are also taken into consideration.
(3) Figures for the last three years are preliminary.
