The Intermediate Challenge is aimed at pupils in Year 11 or below in England and Wales, Year 12 or below in Northern Ireland and S4 or below in Scotland. The top 40% of students nationally receive a gold, silver or bronze certificate in the ratio 1:2:3 and each institution receives a Best in School certificate. Around 500 of the highest scorers in each school year are invited to take part in the Intermediate Mathematical Olympiad papers: Cayley, Hamilton and Maclaurin for year 9, 10 and 11 and equivalent. A further 5,500 pupils from across all three year groups are invited to sit either the grey or pink European Kangaroo papers. High scoring students may be invited to participate in UKMT summer schools.
