Bell curve grading is not used in any of the national examinations - the Primary School Leaving Examination (PSLE), N levels, O levels and A levels - in Singapore, the Ministry of Education (MOE) has said.

A spokesman for the ministry told The Straits Times: "School-based assessments and national examinations are standards-referenced, where the grades awarded reflect a candidate's own level of mastery in the subject based on an absolute set of standards."
