„Given that the curricula for some countries/jurisdictions are written to cater for the whole ability spectrum of students, they can find it challenging to persuade schools and parents not to aim over-ambitiously for some students. Aiming to teach the whole curriculum to all students in the spectrum may be overly ambitious, and may disadvantage low-performing students, as reported by Hong Kong (China).“
