that performance decline relates to basic proficiency. In 1999, over 80% children from the
wealthiest quintile in Jordan attained basic proficiency in math. By 2011, it is less than 80%
among the top wealth quintile. The decline is even bigger among the poorest wealth group (by
almost 10 percentage points). The across-wealth groups decline in math is even more
pronounced in case of attainment of level-2 proficiency (Figure 3.1.6). In terms of level 3
threshold (advanced competency), the sharpest fall in attainment occurred among the top
wealth quintile – it dropped from over 6% in 1999 to less than 2% in 2011 (Figure 3.1.7).
