HOI: Mathematics Proficiency Level 2 indicates how fairly the opportunity to reach mathematics proficiency level 2 is distributed among children. The measure reflects both the proportion attaining the benchmark and the extent to which attainment differs according to personal and household circumstances. These circumstances comprise gender, parental education, the school’s region, the father’s occupation and household wealth, measured through an asset-based index. The indicator can rise when more children achieve the required level, when attainment gaps between circumstance groups narrow, or when both changes occur. It thus goes beyond reporting the share of children who meet the proficiency standard: it also captures disparities in their chances of doing so.
