Mexico, however, still has the lowest percentage of top performers in mathematics in 2009 among OECD countries and the third lowest percentage among the 39 participating countries with comparable data (after Indonesia with 0.1 % and Tunisia with 0.3%) (PISA Results 2009 Volume V,TableV.3.2). Similarly, of the Canadian students who performed below Level 2 in 2000, over 60% had not gone on to any post-school education by the age of 21; by contrast, more than half of the students (55%) who had performed at Level 2 as their highest level were at college or university.' Students proficient at Level 2 in mathematics can employ basic algorithms, formulae, procedures or conventions.
